Product details
Overview
R5F52317BGND#00 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 384 KB on-chip flash, 32 KB SRAM, 8 KB data flash, integrated FPU (IEEE 754 single-precision), and hardware encryption (TSIP-Lite AES-128/256). It targets industrial HMI, sensor fusion nodes, and USB-connected embedded control where deterministic real-time response, secure firmware updates, and low-power RTC operation are required.
For engineers reviewing the R5F52317BGND#00 datasheet, R5F52317BGND#00 pinout, R5F52317BGND#00 application, or R5F52317BGND#00 equivalent, this page delivers verified specifications, package mapping to PWQN0064KC-A (9 × 9 mm HWQFN), validated peripheral feature set per RX231 Group documentation, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F52317BGND#00 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt handling. Its clock system integrates PLL, USB-dedicated PLL (48 MHz output), sub-clock oscillator (32.768 kHz), and CAC for frequency accuracy measurement.
Peripheral integration includes ELC for event-driven module activation without CPU wake-up, DTC for interrupt-triggered transfers, and TSIP-Lite for secure key management and AES-GCM/ECB/CBC operations. The device supports IEC60730-compliant self-test via DOC-assisted RAM test, A/D disconnection detection, and IWDT diagnostics.
