It supports USB 2.0 full-speed host/function/OTG, CAN, SD host interface, capacitive touch sensing (24 channels), 12-bit A/D (24 ch), 12-bit D/A (2 ch), RTC, and operates from 1.8–5.5 V across −40 to +105°C.
For engineers reviewing the R5F52317AGFM#30 datasheet, R5F52317AGFM#30 pinout, R5F52317AGFM#30 application, or R5F52317AGFM#30 equivalent, key selection considerations include its 64-pin LFQFP package (PLQP0064KB-C), absence of CAN and SDHI modules in this variant, presence of USB and CTSU, and G-grade industrial temperature rating.
Technical Context
The R5F52317AGFM#30 belongs to the RX231 Group and implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions. It integrates an on-chip FPU compliant with IEEE 754, a memory protection unit (MPU), and event link controller (ELC) enabling interrupt-free inter-module triggering.
Its clock system includes main (1–20 MHz), sub-clock (32.768 kHz), and multiple on-chip oscillators - including USB-dedicated PLL (4/6/8/12 MHz) and IWDT-dedicated low-speed oscillator. Power management supports three low-power modes, LPT operation during software standby, and voltage detection across three independent circuits.
