You should not use the products or the technology described in this document for the purpose of military applications such as the development of weapons of mass destruction or for the purpose of any other military use. When exporting the products or technology described herein, you should follow the applicable export control laws and regulations, and procedures required by such laws and regulations.4. All information included in this document such as product data, diagrams, charts, programs, algorithms, and application circuit examples, is current as of the date this document is issued. Such information, however, is subject to change without any prior notice. Before purchasing or using any Renesas products listed in this document, please confirm the latest product information with a Renesas sales office. Also, please pay regular and careful attention to additional and different information to be disclosed by Renesas such as that disclosed through our website. (http://www.renesas.com )5. Renesas has used reasonable care in compiling the information included in this document, but Renesas assumes no liability whatsoever for any damages incurred as a result of errors or omissions in the information included in this document.6. When using or otherwise relying on the information in this document, you should evaluate the information in light of the total system before deciding about the applicability of such information to the intended application. Renesas makes no representations, warranties or guaranties regarding the suitability of its products for any particular application and specifically disclaims any liability arising out of the application and use of the information in this document or Renesas products. 7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall have no liability for damages arising out of the uses set forth above.8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below: (1) artificial life support devices or systems (2) surgical implantations (3) healthcare intervention (e.g., excision, administration of medication, etc.) (4) any other purposes that pose a direct threat to human life Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who elect to use Renesas products in any of the foregoing applications shall indemnify and hold harmless Renesas Technology Corp., its affiliated companies and their officers, directors, and employees against any and all damages arising out of such applications. 9. You should use the products described herein within the range specified by Renesas, especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas shall have no liability for malfunctions or damages arising out of the use of Renesas products beyond such specified ranges.10. Although Renesas endeavors to improve the quality and reliability of its products, IC products have specific characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use conditions. Please be sure to implement safety measures to guard against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas product, such as safety design for hardware and software including but not limited to redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other applicable measures. Among others, since the evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or system manufactured by you. 11. In case Renesas products listed in this document are detached from the products to which the Renesas products are attached or affixed, the risk of accident such as swallowing by infants and small children is very high. You should implement safety measures so that Renesas products may not be easily detached from your products. Renesas shall have no liability for damages arising out of such detachment.12. This document may not be reproduced or duplicated, in any form, in whole or in part, without prior written approval from Renesas. 13.

1 1.1 Overview

The M3A-HS85 is the CPU board designed for users to evaluate the functionality and performance of the SH7285

group of Renesas Technology original microcomputer, as well as develop and evaluate the application software for

this group of microcomputers. The Sh7285’s data bus, address bus and various internal peripheral circuit function

pins are connected to the extension connector of the M3A-HS85, allowing users to evaluate the timing relationship

with peripheral devices using measurement instruments or develop extension boards tailored to suit development

purposes. Furthermore, the E10A-USB or the on-chip emulator made by Renesas Technology can also be connected

to the M3A-HS85.

2 2.2 CPU

The M3A-HS85 contains the 32-bit RISC microcomputer SH7285 that operates with a maximum 100MHz of CPU

clock frequency. The SH7285 includes 768-Kbyte flash memory, and 32-Kbyte RAM, making it useful in a wide range

of applications from data processing to equipment control.

The M3A-HS85 can be operated with a maximum 100MHz of CPU clock frequency (external bus maximum 50

MHz) using a 12.5 MHz input clock.

switch jumper (JP1) should be set to “2-3”). SRAM is controlled by the bus state controller built into SH7285. The

address spaces of SRAM can be switched to CS0 space, CS2 space, and CS6 space by the pin function controller

setting of SH7285.

Functional Overview 2.6 Power Supply Module

Rev.1.04 2008.7.10 2-11

REJ10J1564-0104

2 2.6 Power Supply Module

In M3A-HS85, 5V power is input to the board and 3.3V is generated by using a regulator. The regulator used is

output voltage variable type and given voltage value can be generated by changing the resistance value.

5V power can be supplied from DC stabilized power supply (via power supply connector (J4)) and AC adapter (via

DC power supply jack (J7)).

SH7285 system power supply (VCC) can be switched to 3.3V/5V by setting 3V/5V select jumper (JP1)(Initially it is

set to 5V). When VCC is switched, please note the points shown as follows.

• When 5V is set in the state that SRAM or SDRAM is mounted, the voltage that exceeds the maximum rating is

supplied from the address line, data line, and control line to SDRAM or SRAM, and devices could be destroyed. Thus,

using like this must be avoided.

(3.3V is supplied to 3V system device such as SRAM and SDRAM even when 5V is set.)

By setting jumpers, system power (VSS), A/D power (AVCC), AVREF power, and USB power (DrVCC) of SH7285

can be individually supplied from external power supply.

Figure 2.6.1 shows the block diagram of M3A-HS85 power supply circuit.

2.7 USB Interface

The M3A-HS85 contains a USB connector (Standard-B receptacle).

When a cable is connected to USB host/hub in the state that this CPU board is not turned on, the voltage is

impressed from USB host/hub to VBUS. Thus, the CPU board should be turned on before USB cable is connected.

When you want to delay a notification of connection to USB host/hub (the cases such as in the processing of high

priority or initialization), it can be controlled by PB10. The powered state is kept regardless of the states USD+ and

USD- when pin VBUS of SH7285 is set to low level.
