Product details
Overview
R5F52317BGNE#40 from Renesas is a 32-bit RXv2 microcontroller with 54 MHz max operating frequency, 384 KB on-chip flash memory, 32 KB SRAM, and integrated 12-bit A/D converter (24 channels), USB 2.0 full-speed host/function/OTG, CAN interface, capacitive touch sensing unit (24 keys), and TSIP-Lite encryption engine. It targets industrial HMI, smart sensor nodes, and battery-powered control systems requiring real-time performance, secure firmware, and mixed-signal integration.
For engineers reviewing the R5F52317BGNE#40 datasheet, R5F52317BGNE#40 pinout, R5F52317BGNE#40 application, or R5F52317BGNE#40 equivalent, this MCU delivers deterministic 88.56 DMIPS execution, IEEE 754-compliant FPU, low-power RTC operation with battery backup, and IEC60730-ready self-test functions for safety-critical embedded designs.
Technical Context
The R5F52317BGNE#40 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle instruction execution at 54 MHz. It integrates a dedicated USB-dedicated PLL (4/6/8/12 MHz) and system PLL supporting independent clock domains: ICLK (54 MHz), PCLKA (54 MHz), PCLKD (54 MHz), and BCLK (32 MHz).
Its peripheral set includes ELC-driven event-triggered operation across MTU2a, TPU, S12ADE, and CTSU modules-allowing CPU sleep during synchronized data acquisition and waveform generation. The TSIP-Lite engine supports AES-128/256 in GCM/CBC/ECB modes with true random number generation and key protection, meeting secure boot and firmware update requirements.
