R5F52317AGNE#40 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 384 KB on-chip flash, 32 KB SRAM, and integrated FPU compliant to IEEE 754. It features USB 2.0 full-speed host/function/OTG, CAN interface (ISO 11898-1), 24-channel 12-bit A/D converter (0.83 µs conversion), and operates across −40 to +105°C for industrial motor control and HMI applications.
For engineers reviewing the R5F52317AGNE#40 datasheet, R5F52317AGNE#40 pinout, R5F52317AGNE#40 application, or R5F52317AGNE#40 equivalent, this MCU delivers deterministic real-time performance with ELC-triggered peripheral coordination, TSIP-Lite encryption, and hardware-accelerated CRC-critical for IEC 60730-compliant embedded systems requiring secure firmware updates and precise analog sensing.
Technical Context
The R5F52317AGNE#40 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 88.56 DMIPS at 54 MHz. It integrates dual timer units (MTU2a and TPUa) supporting complementary PWM, phase counting, and A/D trigger generation, plus an Event Link Controller enabling CPU-sleep operation of linked peripherals.
Its clock system includes main (1–20 MHz), sub (32.768 kHz), and USB-dedicated PLLs, with independent domain clocks (ICLK/PCLKA/PCLKB/BCLK/FCLK) enabling fine-grained power/performance tuning. The TSIP-Lite engine supports AES-128/256 in GCM/CBC/ECB modes with true random number generation and key protection.
