Body Electronics ApplicationsREQUEST SAMPLES AND DOWNLOAD DOCUMENTATION AT: www.silabs.com/automotive-body-electronics

Automotive body electronics applications are becoming increasingly complex as the demands on these systems extend to enable higher interaction between systems and the rest of the vehicle while adapting to space and energy consumption constraints.

At the foundation of our body electronics portfolio is a family of AEC-Q100 qualified microcontrollers and wireless solutions. Silicon Labs’ products excel in body electronics applications such as anti-pinch window gate lifters for power windows, networked door controls, power seat controls, remote keyless entry and passive keyless entry, heating ventilation and A/C (HVAC) system for climate and comfort control, windshield wiper and rain systems, steering angle measurement and more.

Human Interface and Body Electronics

• Silicon Labs offers the best performing capacitive touch sense solutions in the automotive market. The C8051F7xx/99x families have ultra low standby power for fast system wake-up and keyless functionality.

• LCD displays are commonly used in electronic digital displays because of the extremely low electrical power and low voltage requirements. Silicon Labs’ CP240x can drive those LCD displays up to 128 segments for viewing in bright as well as dark conditions. USB interfaces are also available as bridge ICs for several serial bus standards (UART, I2C, etc..)

• The Si114x infrared proximity and ambient light sensor family, using one to three infrared LEDs, powers functions such as back-lighting control and touchless motion/gesture recognition when driving.

Power SeatsSilicon Labs C8051F5xx automotive microcontrollers are ideal for power seat control where three or more motors are employed to optimize driver seat safety and comfort. The C8051F5xx MCUs, with a built-in 0.5% oscillator over the entire temperature range, allow direct connection to HS CAN and LIN buses without the need for external crystals. Seat control is mostly motor control with mechanical switches. Higher-end seat systems include driver/motor position memory and recall (see page 24) as well as seat surface heaters and cooling systems. Motors in this application are typically brushed. For BLDC and sensor-less BLDC motors see page 25.

Si82xx isolators are added to motor control modules to isolate and eliminate unwanted electrical noise from the motors. Having a low noise floor is critical to the occupant infotainment experience and performance of RF modules.

Passive Keyless EntryPassive keyless systems perform two simple functions: opening a door or trunk hatch with a touch on the handle and allowing the driver to start and stop the car with the push of a button. To realize these functions, a technologically advanced system is required that includes a new generation HF/LF fob and an in-cabin base station with its associated set of LF antennas plus touch sensors. The Si401x is an excellent choice for a single IC fob, integrating the MCU, AES-128 encryption, and RF transmitter. Silicon Labs’ EZRadioPRO® transceiver, complimented by the ultra low power C8051F98x/9x MCU offers a very high communication link budget (>130 dB) as well as very low power while in standby mode to preserve battery life.

Networked Door and MirrorVehicle doors continue to evolve in the areas of safety and functionality. Silicon Labs’ C8051F5xx automotive MCUs are compelling solutions for controlling all door and integrated mirror functions. The C8051F5xx MCUs offer a crystal-less CAN bus and LIN bus communication gate between the body control module (BCM) and the door functions. For the motor control for window lift and mirror position (see page 7) the C8051F5xx provides high processing power, providing interlock and pinch signature algorithms to simplify automotive window obstruction detection and eliminate the need for a separate interlock system. For vehicles with passive entry systems, the door handles need a touch sensor with excellent outdoor performance and are suitable for use with gloves. Silicon Labs’ C8051F99x capacitive touch sense MCUs lead the industry in lowest power, highest capacitive touch performance, and best value/performance ratio.

The ADC variable attenuation feature is very useful when interfacing to a variety of sensors. Communications are through the integrated LIN 2.1 controller that operates off the internal 0.5% precision oscillator. Add to this the built-in 1.8 V to 5.25 V LDO regulator, and you have a high performance system solution at a very low cost.

Windshield and Rearview Mirror SystemsAutomotive windshield systems are rapidly evolving from the three basic functions: wipers, washers, and defrost. Silicon Labs’ C8051F5xx helps modernize these functions with features such as CAN, LIN or other serial networking to reduce wiring harness weight and cost as well as opening the design for new features, including efficient motor control for wiper and fluid pump motors which is especially important for vehicle electrification in mild hybrids with stop/start functionality and HEV/EVs.

The rearview mirror is becoming an increasingly complex system (compass, outside temperature, rain sensing, and glass dewpoint/condensation detecting). Silicon Labs’ Si114x is ideal for motion detection associated with rain on the glass, day or night. Coupled with the C8051F5xx MCU, the system provides the interface, control and data for rain detection, outside temperature, glass condensation, compass sensors and automated HVAC windshield defrost.

Tire Pressure MonitorTire pressure monitoring systems (TPMS), required in the US and increasingly elsewhere, demand a high-performance, frequency hopping receiver such as Silicon Labs’ Si4xxx EZRadioPRO® that can be shared with RKE/PKE access systems. The wheel component of TPMS monitors the pressure and temperature every few seconds and transmits the data over RF frequency. The monitoring is typically done in short bursts every few seconds to save battery life. The tire module batteries are rated at 85 °C max and are expected to last 7-10 years in the application. Most of the time, batteries are sealed into the TPMS module and cannot be replaced. Coupled with an RF transmitter and pressure sensor, Silicon Labs’ C8051F99x with RTC wake-up is the lowest power solution available. An alternate option is the Si401x, which integrates the MCU and TX functions in a single chip.

Back-Up Camera (Rearview Video, Parking Assistance System)Rear vision systems are a rapidly growing safety related application that will be accelerated to 100% in the US if proposed legislation is passed, requiring MY2014 vehicles to be in compliance.

Silicon Labs’ C8051F5xx automotive MCU solutions have the right balance of functionality, size and cost for this application. The MCU is the central controller, interfacing via CAN or LIN (without an external oscillator) to the body control module (BCM). The C8051F5xx MCU enables the camera when the vehicle is shifted in reverse, and can then transmit steering angle position (see page 12) for dynamic visual overlay guides calculated by the image processor.

Stepper MotorStepper motors are used when accurate positioning is required. Controlling the position of a stepper motor is achieved by energizing stator windings that allow the stator to align with permanent magnets mounted on the rotor. The MCU controls the sequence of pulses that are applied to the windings to control speed and direction.

Brushed and BLDC MotorBLDC motors are popular as their current-to-torque and voltage-to-speed relationships are linear. Brushless dc motors have the advantage of electronic commutation and do not require brush maintenance typical of mechanically commutated motors. The MCU generates gate drive signals and the on-chip analog-to-digital converter is used to measure feedback from voltage, current and position sensors.
