Overview
R5F52317BDNE#U0 from Renesas is a 32-bit RXv2 core MCU 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 2.0B (1 Mbps), 24-channel 12-bit ADC (0.83 µs conversion), dual 12-bit DAC, RTC with battery backup, and capacitive touch sensing (10 channels) - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and secure connectivity.
For engineers reviewing the R5F52317BDNE#U0 datasheet, R5F52317BDNE#U0 pinout, R5F52317BDNE#U0 application, or R5F52317BDNE#U0 equivalent, this page delivers verified specifications, package mapping to PWQN0048KB-A (7 × 7 mm, 0.5 mm pitch), validated peripheral integration (USB/CAN/ADC/DAC), confirmed low-power modes (deep sleep, software standby), and two field-tested alternative MCUs for migration or second-sourcing.
Technical Context
The R5F52317BDNE#U0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling 1-instruction-per-cycle execution at 54 MHz. Its memory subsystem includes 384 KB flash (no-wait up to 32 MHz), 32 KB SRAM (no-wait at 54 MHz), and 8 KB data flash rated for 1M program/erase cycles with background operation (BGO).
Peripheral integration centers on event-driven operation via the Event Link Controller (ELC), supporting interrupt-free module triggering and linked operation during CPU sleep. Clock management includes independent PLL (system clock), USB-dedicated PLL (48 MHz), sub-clock oscillator (32.768 kHz), and CAC for frequency accuracy monitoring - all configurable per functional domain (ICLK, PCLKA/B/D, BCLK, FCLK).
