Product details
Overview
R5F51305ADFL#10 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 128 KB on-chip flash, 16 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 R5F51305ADFL#10 datasheet, R5F51305ADFL#10 pinout, R5F51305ADFL#10 application, or R5F51305ADFL#10 equivalent, key selection criteria include its 48-pin LFQFP package (7 × 7 mm, 0.5 mm pitch), –40°C to +85°C temperature grade, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, and integrated event link controller (ELC) for interrupt-free peripheral coordination.
Technical Context
The R5F51305ADFL#10 implements the 32-bit RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling 1-instruction-per-cycle execution and 64-bit accumulator support for 32×32-bit operations. It integrates a dedicated low-power timer (LPT) running from sub-clock or IWDT oscillator during software standby mode, with 4.8 µs wake-up latency.
Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), PLL (4–8 MHz input), sub-clock (32.768 kHz), and clock accuracy measurement circuit (CAC). Peripheral coordination is handled by the Event Link Controller (ELC), allowing direct module triggering without CPU intervention - critical for deterministic low-power sensor node operation.
