240 MHz G3KH core with 2 MB on-chip flash
The R7F7017643AFP-C#BA1: The RH850G3KH core runs at 240 MHz, placing this MCU in the high-throughput tier for real-time control loops — a domain controller reading multiple CAN buses and executing torque-vectoring or transmission logic needs the clock headroom above 200 MHz to close the loop within a single 5 ms task cycle. 2 MB of program flash (2M x 8) with 256K x 8 RAM and 128K x 8 EEPROM-on-chip means the application image, data stacks, and calibration tables all fit without external memory — the EEPROM block is sized for fault-log storage and adaptive parameters over the vehicle lifetime.
Peripheral integration for body and domain control
Connectivity includes CANbus, CSI, I²C, LINbus, SPI, and UART/USART — the CAN and LIN interfaces directly match the automotive backbone, while CSI and SPI handle local sensor clusters and actuator drivers. 144 I/O pins give headroom for multiplexed switch inputs and LED diagnostics. The ADC bank offers 38 channels at 10-bit and 32 channels at 12-bit — the 12-bit group is the one to budget for analog sensors (throttle position, pressure, temperature) where 10 mV resolution on a 5 V reference is the difference between a valid reading and noise. On-chip peripherals include DMA, PWM, and WDT — the DMA engine offloads the core during high-rate CAN reception, and the PWM timers drive solenoid or H-bridge outputs directly without external pulse-generation logic.
Supply and temperature envelope for automotive duty
Operating temperature is -40°C to 105°C ambient — this is the under-hood / engine-bay band. A transmission ECU or engine controller sitting near the block sees 105°C on a summer-grade thermal profile; the 105°C rating leaves margin above the 85°C industrial limit.
The tray packaging is standard for automated pick-and-place; no moisture-sensitive bake is required if the floor-life limit is observed.
