Product details
Overview
R5F52317AGFP#30 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 supports USB 2.0 full-speed host/function/OTG, CAN, SD host interface, 24-channel 12-bit ADC, dual 12-bit DAC, capacitive touch sensing (24 keys), RTC with battery backup, and operates across −40 to +105°C in industrial applications.
For engineers reviewing the R5F52317AGFP#30 datasheet, R5F52317AGFP#30 pinout, R5F52317AGFP#30 application, or R5F52317AGFP#30 equivalent, key selection considerations include its 100-pin LFQFP package (PLQP0100KB-B), G-grade temperature rating, absence of CAN and SDHI modules versus higher-memory variants, and compatibility with Renesas' RX231 Group toolchain and E2 studio IDE.
Technical Context
The R5F52317AGFP#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and fast interrupt response. Its clock system integrates PLL, USB-dedicated PLL (48 MHz), sub-clock oscillator (32.768 kHz), and CAC for frequency accuracy measurement.
Peripheral integration includes ELC for event-driven module activation without CPU intervention, DTC for interrupt-triggered transfers, and MPC for flexible pin function assignment. The MCU supports IEC60730-compliant self-test via DOC-assisted RAM test, A/D disconnection detection, and IWDT diagnostics.
