Product details
Overview
R5F52316AGFM#30 from Renesas is a 32-bit RXv2 microcontroller with 256 KB on-chip flash, 32 KB SRAM, and 8 KB data flash, operating at up to 54 MHz (88.56 DMIPS) with integrated FPU, 12-bit A/D converter (24 channels), USB 2.0 full-speed host/function/OTG, and capacitive touch sensing unit - deployed in industrial HMI and consumer appliance control systems.
For engineers reviewing the R5F52316AGFM#30 datasheet, R5F52316AGFM#30 pinout, R5F52316AGFM#30 application, or R5F52316AGFM#30 equivalent, this MCU delivers verified real-time performance, IEC60730-compliant safety functions, low-power RTC operation, and hardware-accelerated AES encryption via TSIP-Lite - critical for secure, battery-backed embedded control designs.
Technical Context
The R5F52316AGFM#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions, supporting IEEE 754-compliant single-precision floating-point operations and 32-bit multiply-accumulate DSP instructions. It integrates an event link controller (ELC) enabling interrupt-free peripheral coordination and a memory protection unit (MPU) for secure task isolation.
Its clock system includes main (1–20 MHz), sub-clock (32.768 kHz), and USB-dedicated PLLs, allowing independent 54 MHz system clock and 48 MHz USB clock generation. The device supports three low-power modes - sleep, deep sleep, and software standby - with low-power timer (LPT) active during standby and RTC powered from battery backup.
