SAMA5D27C AUTO

1. DescriptionThe SAMA5D27C-CNVAO is a high-performance, power-efficient embedded MPU based on the ARM Cortex-A5 processor. It integratesthe ARM NEON SIMD engine for accelerated multimedia and signal processing, a configurable 128-Kbyte L2 cache, a floating point unitfor high-precision computing and reliable performance, as well as high data bandwidth architecture. The device features an advanced userinterface and connectivity peripherals. Advanced security is provided by powerful cryptographic accelerators, by the ARM TrustZone tech-nology securing access to memories and sensitive peripherals, and by several hardware features that safeguard memory content, authen-ticate software reliability, detect physical attacks and prevent information leakage during code execution.

The SAMA5D27C-CNVAO features an internal multilayer bus architecture associated with 2 x 16 DMA channels and dedicated DMAs forthe communication and interface peripherals required to ensure uninterrupted data transfers with minimal processor overhead. The devicesupports DDR2, DDR3, DDR3L, LPDDR1, LPDDR2, LPDDR3, and SLC/MLC NAND Flash memory up to 32-bit ECC.

The comprehensive peripheral set includes an LCD TFT controller with overlays for hardware-accelerated image composition, an imagesensor controller, audio support through I2S, SSC, a stereo Class D amplifier and a digital microphone. Connectivity peripherals includea 10/100 EMAC, USBs, CAN-FDs, FLEXCOMs, UARTs, SPIs and two QSPIs, SDIO/SD/e.MMCs, and TWIs/I2C.

Protection of code and data is provided by automatic scrambling of memories and an Integrity Check Monitor (ICM) to detect any modifi-cation of the memory contents. The SAMA5D27C-CNVAO also supports execution of encrypted code (QSPI or one portion of the DDR)with an on-the-fly encryption-decryption process.

With its secure design architecture, cryptographic acceleration engines, and secure boot loader, the SAMA5D27C-CNVAO is the idealsolution for point-of-sale (POS), IoT and industrial applications requiring anti-cloning, data protection and secure communication transfer.

The SAMA5D27C-CNVAO features three software-selectable low-power modes: Idle, Ultra-low-power and Backup.

In Idle mode, the processor is stopped while all other functions can be kept running.

In Ultra-low-power-mode 0, the processor is stopped while all other functions are clocked at 512 Hz and interrupts or peripherals can beconfigured to wake up the system based on events, including partial asynchronous wakeup (SleepWalking).

In Ultra-low-power mode 1, all clocks and functions are stopped but some peripherals can be configured to wake up the system based onevents, including partial asynchronous wakeup (SleepWalking).

In Backup mode, RTC and wakeup logic are active. The Backup mode can be extended to feature DDR in Self-refresh mode.

The SAMA5D27C-CNVAO also includes an Event System that allows peripherals to receive, react to and send events in Active and Idlemodes without processor intervention.

6. Safety and Security Features

6.1 Design for Safety and IEC60730 Class B Certification

6.1.1 Background InformationThe IEC 60730 standard encompasses all aspects of appliance design. Annex H of the standard covers the aspects most relevant tomicrocontrollers. It details the tests and diagnostics which are intended to ensure safe operation of embedded control hardware and soft-ware. IEC 60730 defines three classifications for electronic control functions:

Class A - Control functions which are not intended to be relied upon for safety of the equipment Class B - Control functions intended to prevent unsafe operation of the controlled equipment Class C - Control functions intended to prevent special hazards such as explosionsSpecific design techniques have been used in the SAMA5D27C-CNVAO to ease compliance with the IEC 60730 Class B Certification andto resolve general-purpose safety concerns. This allows reduced software development and code size as well as savings on external hard-ware circuitry, since built-in self-tests are already embedded in the MPU. Table 6-1 gives the list of peripherals which incorporate thesetechniques, and details whether these features are applicable for the IEC 60730 Class B Certification or for general-purpose safety con-siderations.

6.2 Design for SecurityThe SAMA5D27C-CNVAO embeds peripherals with security features to prevent counterfeiting, to secure external communication, and toauthenticate the system.

Table 6-2 provides the list of peripherals and an overview of their security function. For more information, see the sections on each periph-eral.

2: The reset state of GPIOs is not guaranteed during the powerup phase. During this phase, the GPIOs are in input pullup modeand they take their reset value only after VDDCORE POR reset has been released. If a GPIO must be at level zero at powerup,it is recommended to connect an external pulldown to guarantee this state.

3: For NRST usage, refer to Section 69.5 Reset and Test.

8. Power Considerations

8.1 Power Supplies

8.2 Powerup ConsiderationsAt powerup, from a supply sequencing perspective, the power supply inputs are categorized into two groups:

Group 1 (core group) contains VDDCORE, VDDUTMIC, VDDHSIC and VDDPLLA. Group 2 (periphery group) contains all other power supply inputs except VDDFUSE.Figure 8-1 shows the recommended powerup sequence. Note that:

VDDBU, when supplied from a battery, is an always-on supply input and is therefore not part of the power supply sequencing. When no backup battery is present in the application, VDDBU is part of Group 2.

VDDFUSE is the only power supply that may be left unpowered during operation. This is possible if and only if the application does not access the Customer Fuse Matrix in Write mode. It is good practice to turn on VDDFUSE only when the Customer Fuse Matrix is accessed in Write mode, and to turn off VDDFUSE otherwise.

VDDIODDR may be nominally supplied at 1.2V when the device is equipped with an LPDDR2 or LPDDR3 memory. In this case, VDDIODDR can be considered as part of Group 1.

8.3 Powerdown ConsiderationsFigure 8-2 shows the powerdown sequence that starts by asserting the NRST line to 0. Once NRST is asserted, the supply inputs can beimmediately shutdown without any specific timing or order. VDDBU may not be shutdown if the application uses a backup battery on thissupply input. In applications where VDDFUSE is powered, it is mandatory to shutdown VDDFUSE prior to removing any other supply.VDDFUSE can be removed before or after asserting the NRST signal.

Figure 8-2: Recommended Powerdown Sequence

8.4 Power Supply Sequencing at Backup Mode Entry and Exit

8.4.1 VDDBU Power ArchitectureThe backup power switch aims at optimizing the power consumption on VDDBU source by switching the supply of the backup digital part(BUREG memories + 64-kHz RC oscillator) to VDDANA.

When enabled, the backup power source can be automatically switched to VDDANA, which reduces power consumption on VDDBU.Then, VDDBU powers the pads, VDDBU POR and 32-kHz crystal.

The power source (VDDANA or VDDBU) can be selected manually or can be set to work automatically by programming an SFRBU register(refer to SFRBU_PSWBUCTRL in Section 21. Special Function Registers Backup (SFRBU)).

8.4.2 Backup Mode EntryFigure 8-3 shows the recommended power down sequence to place the device either in Backup mode or in Backup mode with its DDR inself-refresh. The SHDN signal, output of Shutdown Controller (SHDWC), signals the shutdown request to the power supply. This outputis supplied by VDDBU that is present in Backup mode. Placing the external DDR memory in self-refresh while in Backup mode, requiresto maintain also VDDIODDR. One possible way to signal this additional need to the power supply is to position one of the general purposeI/Os supplied by VDDBU (PIOBUx) in a predefined state.

8.4.3 Backup Mode Exit (Wakeup)Figure 8-4 shows the recommended powerup sequence to wake up the device from Backup mode. Upon a wakeup event, the ShutdownController toggles its SHDN output back to VDDBU to request the power supply to restart. Except VDDIODDR which may already be pres-ent if the external DDR memory was placed in Self-refresh mode, this powerup sequence is the same as the one of Figure 8-1. In particular,the definitions of Group 1 and Group 2 are the same.

9.1 Embedded Memories

9.1.1 Internal SRAMThe SAMA5D27C-CNVAO embeds a total of 128 Kbytes of high-speed SRAM. After reset, and until the Remap command is performed,the SRAM is accessible at address 0x0020 0000. When the AXI Bus Matrix is remapped, the SRAM is also available at address 0x0.

The device features a second 128-Kbyte SRAM that can be allocated either to the L2 cache controller or used as an internal SRAM. Afterreset, this block is connected to the system SRAM, making the two 128-Kbyte RAMs contiguous. The SRAM_SEL bit, located in theSFR_L2CC_HRAMC register, is used to reassign this memory as a L2 cache memory.

9.1.2 Internal ROMThe product embeds one 160-Kbyte secured internal ROM mapped at address 0 after reset. The ROM contains a standard and securebootloader as well as the BCH (Bose, Chaudhuri and Hocquenghem) code tables for NAND Flash ECC correction. The memory area con-taining the secure boot is automatically hidden after the execution of the secure boot while the one containing the code tables for ECCremains visible.

9.1.3 Boot StrategiesFor standard boot strategies, refer to Section 17. Standard Boot Strategies of this datasheet.

For secure boot strategies, refer to the document SAMA5D2x Secure Boot Strategy, document no. 44040 (Non-Disclosure Agreementrequired).

9.2 External MemoryThe SAMA5D27C-CNVAO offers connections to a wide range of external memories or to parallel peripherals.

9.2.1 External Bus InterfaceThe External Bus Interface (EBI) is a 16-bit wide interface working at MCK/2.

The EBI supports:

Static memories 8-bit NAND Flash with 32-bit BCH ECC 16-bit NAND FlashEBI I/Os accept three drive levels (Low, Medium, High) to avoid overshoots and provide the best performances according to the bus loadand external memories voltage.

The drive levels are configured with the DRVSTR field in the PIO Configuration Register (PIO_CFGRx) if the corresponding line is non-secure or the Secure PIO Configuration Register (S_PIO_CFGRx) if the I/O line is secure.

At reset, the selected drive is low. The user must make sure to program the correct drive according to the device load. The I/O embedsserial resistors for impedance matching.

9.2.2 Supported Memories on DDR2/DDR3/LPDDR1/LPDDR2/LPDDR3 Interface 16-bit or 32-bit external interface 512 Mbytes of address space on DDR CS and DDR/AES CS in 32-bit mode 256 Mbytes of address space on DDR CS and DDR/AES CS in 16-bit mode Supports 16-bit or 32-bit 8-bank DDR2, DDR3, LPDDR1, LPDDR2 and LPDDR3 memories Automatic drive level control Multiport Scramblable data path Port 0 of this interface has an embedded automatic AES encryption and decryption mechanism (refer to Section 60. Advanced

Encryption Standard Bridge (AESB)). Writing to or reading from the address 0x40000000 may trigger the encryption and decryption mechanism depending on the AESB on External Memories configuration.

TrustZone: The multiport feature of this interface implies TrustZone configuration constraints. Refer to Section 19.12 TrustZone Extension to AHB and APB for more details.

9.2.3 Supported Memories on Static Memories and NAND Flash InterfacesThe Static Memory Controller is dedicated to interfacing external memory devices:

Asynchronous SRAM-like memories and parallel peripherals


SAMA5D27C AUTO

NAND Flash (MLC and SLC) 8-bit datapathThe Static Memory Controller is able to drive up to four chip select. NCS3 is dedicated to the NAND Flash control.

The HSMC embeds a NAND Flash Controller (NFC). The NFC can handle automatic transfers, sending the commands and address cyclesto the NAND Flash and transferring the contents of the page (for read and write) to the NFC SRAM. It minimizes the processor overhead.

In order to improve overall system performance, the DATA phase of the transfer can be DMA-assisted. The static memory embeds theNAND Flash Error Correcting Code controller with the following features:

Algorithm based on BCH codes Supports also SLC 1-bit (BCH 2-bit), SLC 4-bit (BCH 4-bit) Programmable Error Correcting Capability

- 2-bit, 4-bit, 8-bit and 16-bit errors for 512 bytes/sector (4-Kbyte page)- 24-bit error for 1024 bytes/sector (8-Kbyte page)

9.2.4.1 DDR I/O CalibrationThe DDR2/DDR3/LPDDR1/LPDDR2/LPDDR3/DDR3L I/Os embed an automatic impedance matching control to avoid overshoots andreach the best performance levels depending on the bus load and external memories. A serial termination connection scheme, where thedriver has an output impedance matched to the characteristic impedance of the line, is used to improve signal quality and reduce EMI.

One specific analog input, DDR_CAL, is used to calibrate all DDR / IOs.

The MPDDRC supports the ZQ calibration procedure used to calibrate the DDR I/O drive strength and the commands to setup the externalDDR device drive strength (refer to Section 37. Multiport DDR-SDRAM Controller (MPDDRC)). The calibration cell supports all the mem-ory types listed above.

- 24 K for LPDDR2/LPDDR3- 23 K for DDR3L- 22 K for DDR3- 21 K for DDR2/LPDDR1

The typical value for CZQ is 22 pF.

LPDDR2 Power Fail ManagementThe DDR controller (MPDDRC) is used to manage the LPDDR memory when an uncontrolled power off occurs.

The DDR power rail must be monitored externally and generate an interrupt when a power fail condition is triggered. The interrupt handlermust apply the sequence defined in the MPDDRC Low-power register (MPDDRC_LPR) by setting bit LPDDR2_PWOFF (LPDDR2 PowerOff bit).

9.2.4.2 SDMMC I/O CalibrationThe device also embeds an SDMMC I/O calibration cell. The purpose of this block is to provide to e.MMC/SD I/Os an output impedancereference to limit the impact of process, voltage and temperature on the drivers output impedance. The impedance control is required athigh frequency in order to improve signal quality.

The control and procedure to setup the SDMMC calibration cell is described in Section 52. Secure Digital MultiMedia Card Controller(SDMMC).

Figure 9-3: SDMMC I/O Calibration Cell

The calibration cell provides an input pin SDCAL loaded with a 20 K resistor for 1.8V memories and a 16.9 K resistor for 3.3V memories.

According to the e.MMC specification, the output impedance calibration is mandatory for HS200 mode (1.8V) when it is not for other modes(3.3V).

In addition, according to the SD specification, the output impedance calibration is mandatory for 1.8V signaling when it is not for 3.3Vsignaling.

Thus, the calibration cell design is oriented to get the highest accuracy under 1.8V.

In case of interfacing which would need to operate under both 1.8V and 3.3V, external devices RZQ and CZQ must get values related tothe 1.8V mode. The typical value for CZQ is 22 pF.

10. Event SystemThe events generated by peripherals are designed to be directly routed to peripherals managing/using these events without processorintervention. Peripherals receiving events contain logic by which to select the one required.

10.1 Real-time Event List Timers, PWM, IO peripherals generate event triggers which are directly routed to event managers such as ADC, for example, to start

measurement/conversion without processor intervention. ADC is connected to nine trigger inputs defined as two groups:

- One group of eight elements for Timer Counter (TC0 to TC4), ADTRIG and PMW0 event0, PWM0 event1- One group of one element for low-rate trigger, RTC

UART, USART, SPI, TWI, PWM, CLASSD, AES, SHA, ADC, PIO, TIMER (Capture mode) generate event triggers directly connected to DMA controllers (XDMAC) for data transfer without processor intervention.

PWM safety events (faults) are in combinational form and directly routed from event generators (ADC, ACC, PMC, TIMER) to the PWM module.

PWM receives external triggers to provide PFC, DC/DC functions. PWM output comparators generate events directly connected to TIMER. PMC safety event (clock failure detection) can be programmed to switch the MCK on a reliable main RC internal clock without pro-

cessor intervention.
