Product details
Overview
R5F52317BDFM#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 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 (24 keys) - deployed in industrial HMI and smart sensor nodes requiring deterministic real-time control and secure firmware updates.
For engineers reviewing the R5F52317BDFM#30 datasheet, R5F52317BDFM#30 pinout, R5F52317BDFM#30 application, or R5F52317BDFM#30 equivalent, this MCU delivers verified USB-CAN coexistence, IEC60730-compliant self-test functions (ADC, IWDT, RAM), low-power software standby with LPT operation, and ELC-driven event-triggered peripheral coordination without CPU wake-up - critical for battery-powered edge controllers and functional-safety-aware designs.
Technical Context
The R5F52317BDFM#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU-enforced memory protection. Its clock system integrates PLL, USB-dedicated PLL (48 MHz), sub-clock oscillator (32.768 kHz), and CAC for frequency accuracy validation - enabling precise timing for USB, RTC, and synchronous serial interfaces.
Peripheral coordination is managed via Event Link Controller (ELC), supporting 61 event sources and direct module triggering (e.g., MTU2a start A/D conversion on timer match). The TSIP-Lite engine provides AES-GCM/CBC/ECB with true random number generation and key protection, while the DOC unit accelerates 16-bit arithmetic for sensor signal processing.
