Overview
R5F52316ADFL#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, 12-bit A/D converter (24 channels), and 12-bit D/A converter (2 channels). It integrates USB 2.0 full-speed host/function/OTG, CAN, SCI, I²C, RSPI, capacitive touch sensing (24 keys), RTC, FPU, TSIP-Lite encryption, and operates across −40 to +85°C in a 48-pin LFQFP package.
For engineers reviewing the R5F52316ADFL#30 datasheet, R5F52316ADFL#30 pinout, R5F52316ADFL#30 application, or R5F52316ADFL#30 equivalent, this MCU delivers deterministic real-time control with IEEE 754-compliant floating-point math, hardware-accelerated crypto, and low-power operation down to software standby mode - critical for industrial HMI, smart sensor nodes, and USB-connected embedded controllers requiring functional safety support per IEC 60730.
Technical Context
The R5F52316ADFL#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports little-endian or big-endian data arrangement and includes an on-chip FPU compliant with IEEE 754 single-precision standards, plus a 32-bit × 32-bit multiplier and 32-bit divider with two-cycle minimum execution.
Its clock system integrates main (1–20 MHz), sub (32.768 kHz), and on-chip oscillators, with PLLs generating 54 MHz system clock and 48 MHz USB clock. The ELC enables interrupt-free inter-module triggering, while the MPU enforces memory protection - both essential for certified control firmware and secure boot implementations.
