Product details
Overview
R5F52317BDFL#10 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), 12-bit D/A converter (2 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 processing, secure firmware updates, and low-power operation down to software standby mode.
For engineers reviewing the R5F52317BDFL#10 datasheet, R5F52317BDFL#10 pinout, R5F52317BDFL#10 application, or R5F52317BDFL#10 equivalent, key selection criteria include its 48-pin LFQFP package (PLQP0048KB-B), −40 to +85°C temperature grade (D version), absence of SDHI and CAN support in this variant, and compatibility with Renesas' e2 studio and CS+ development tools.
Technical Context
The R5F52317BDFL#10 implements the RXv2 CPU core with IEEE 754-compliant single-precision FPU, 32-bit multiply-accumulate instructions, and memory protection unit (MPU) for safety-critical tasks. Its clock system supports main oscillator (1–20 MHz), sub-clock (32.768 kHz), and USB-dedicated PLL (4/6/8/12 MHz), enabling independent 54 MHz system clock and 48 MHz USB clock generation.
Peripheral integration includes ELC for interrupt-free module linking, DTC for efficient data transfers, and CTSU supporting self-capacitance up to 24 keys. The device lacks SDHI and CAN modules per Table 1.2 - confirmed for 48-pin RX231 Group variants - and uses only SCIg (4 channels), RIIC, RSPI, and USBd for communication.
