Product details
Overview
R5F51303AGFL#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) across –40°C to +105°C. It integrates a 12-bit A/D converter (10 channels), two 8-bit D/A outputs, capacitive touch sensing (24 keys), RTC, low-power timer, and dual SCI/I²C/RSPI interfaces - deployed in industrial control panels requiring robust IEC60730-compliant timing and analog sensing.
For engineers reviewing the R5F51303AGFL#30 datasheet, R5F51303AGFL#30 pinout, R5F51303AGFL#30 application, or R5F51303AGFL#30 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-B) package, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, and support for event-driven peripheral linking via ELC without CPU wake-up.
Technical Context
The R5F51303AGFL#30 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and dedicated IWDT oscillator (15 kHz), all configurable via CAC for accuracy validation.
Peripheral coordination is managed by the Event Link Controller (ELC), enabling direct module-to-module triggering (e.g., MTU → A/D start) while CPU remains in deep sleep. The Data Transfer Controller (DTC) supports normal, repeat, and block transfer modes activated by 47 event sources - critical for deterministic sensor data acquisition in battery-powered systems.
