Product details
Overview
R5F51308ADFN#10 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 (17 channels), two 8-bit D/A outputs, capacitive touch sensing (36 channels), RTC, and IEC60730-compliant safety functions - deployed in industrial HMI and consumer appliance control systems.
For engineers reviewing the R5F51308ADFN#10 datasheet, R5F51308ADFN#10 pinout, R5F51308ADFN#10 application, or R5F51308ADFN#10 equivalent, key selection criteria include its 80-pin LFQFP package (PLQP0080KB-B), 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and integrated ELC/DTC for low-power peripheral coordination without CPU intervention.
Technical Context
The R5F51308ADFN#10 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates an Event Link Controller (ELC) supporting 47 event sources and direct module-to-module triggering - allowing timer-triggered A/D conversion, PWM waveform generation, and RTC alarm actions while the CPU remains in deep sleep mode.
Its clock system includes a 32 MHz ±1% high-speed on-chip oscillator, sub-clock (32.768 kHz) for RTC, and Clock Accuracy Measurement (CAC) circuit for IEC60730 compliance. Power management features three low-power modes, a 16-bit Low Power Timer (LPT) running on sub-clock, and supply current as low as 96 µA/MHz in high-speed operation.
