Overview
R5F51308ADFL#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 KB on-chip flash, 48 KB SRAM, 8 KB data flash, 12-bit A/D converter (10 channels), two 8-bit D/A outputs, capacitive touch sensing (24 keys), and IEC60730-compliant safety functions - deployed in industrial control panels requiring low-power operation and embedded touch interfaces.
For engineers reviewing the R5F51308ADFL#30 datasheet, R5F51308ADFL#30 pinout, R5F51308ADFL#30 application, or R5F51308ADFL#30 equivalent, key selection criteria include its 48-pin LFQFP (7×7 mm, 0.5 mm pitch) package, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and support for ELC-triggered peripheral coordination without CPU intervention.
Technical Context
The R5F51308ADFL#30 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates a dedicated event link controller (ELC) that routes 47 event signals directly between peripherals - such as MTU2 timers, A/D converter, and SCI - enabling autonomous operation during CPU sleep.
Its clock system includes high-speed (32 MHz ±1%) and low-speed (15 kHz) on-chip oscillators, PLL, sub-clock (32.768 kHz), and clock accuracy measurement circuit (CAC). Power management supports three low-power modes, with software standby mode sustaining RTC and LPT operation while drawing only 0.37 µA.
