Product details
Overview
R5F52318BDFM#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 54 MHz (88.56 DMIPS), featuring 512 KB on-chip flash, 64 KB SRAM, 8 KB data flash, integrated FPU (IEEE 754 single-precision), and hardware encryption (TSIP-Lite AES-128/256). It serves as a main application controller in industrial HMI and smart sensor nodes requiring real-time processing, secure firmware updates, and low-power operation down to 1.8 V.
For engineers reviewing the R5F52318BDFM#30 datasheet, R5F52318BDFM#30 pinout, R5F52318BDFM#30 application, or R5F52318BDFM#30 equivalent, key selection criteria include its 64-pin LFQFP package with 47 GPIOs, dual 12-bit ADC (24-channel) + dual 12-bit DAC, USB 2.0 full-speed host/function/OTG, CAN 2.0B, SD host interface, capacitive touch sensing (10-key support), and −40 to +85°C temperature rating.
Technical Context
The R5F52318BDFM#30 belongs to the RX231 Group and implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions. It integrates an on-chip FPU compliant with IEEE 754, a memory protection unit (MPU), and event link controller (ELC) enabling interrupt-free inter-module triggering - critical for deterministic real-time control loops.
Its clock system includes PLL, USB-dedicated PLL (48 MHz output), sub-clock oscillator (32.768 kHz), and clock frequency accuracy measurement circuit (CAC). Power management supports three low-power modes (sleep, deep sleep, software standby), with LPT running during software standby and RTC operating on battery backup.
