Product details
Overview
R5F51303ADFL#30 from Renesas is a 32-bit RX CPU-based microcontroller with 64 KB flash, 10 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), supporting capacitive touch sensing (24 keys), 12-bit A/D conversion (10 channels), dual 8-bit D/A outputs, and IEC60730-compliant safety functions for industrial control panels and appliance HMI systems.
For engineers reviewing the R5F51303ADFL#30 datasheet, R5F51303ADFL#30 pinout, R5F51303ADFL#30 application, or R5F51303ADFL#30 equivalent, key selection criteria include its 48-pin LFQFP package (7×7 mm, 0.5 mm pitch), 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and integrated CTSU/RTC/IWDT for low-power human-interface and timing-critical embedded designs.
Technical Context
The R5F51303ADFL#30 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) that enables inter-module triggering without CPU intervention-critical for deterministic real-time response in motor control and sensor acquisition.
Its clock system includes a high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and Clock Accuracy Measurement (CAC) circuit-supporting precise RTC calibration and fail-safe clock monitoring required for IEC60730 Class B compliance in white goods and industrial controllers.
