Product details
Overview
R5F51303AGFK#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller in the RX130 Group, operating at up to 32 MHz (50 DMIPS), featuring 64 KB flash, 10 KB SRAM, 8 KB data flash, 12-bit A/D converter (14 channels), two 8-bit D/A outputs, capacitive touch sensing (32 channels), and IEC60730 compliance for safety-critical industrial control applications.
For engineers reviewing the R5F51303AGFK#10 datasheet, R5F51303AGFK#10 pinout, R5F51303AGFK#10 application, or R5F51303AGFK#10 equivalent, key selection criteria include its LQFP-64 (0.8 mm pitch) package, –40°C to +105°C extended temperature grade, integrated RTC (binary/calendar mode), low-power software standby mode (0.37 µA), and ELC-driven event-linked peripheral operation without CPU intervention.
Technical Context
The R5F51303AGFK#10 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and on-chip debugging via FINE interface. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for frequency accuracy measurement - all configurable for independent ICLK, PCLKB, and FCLK domains.
Peripheral coordination is managed by the Event Link Controller (ELC), enabling direct module-to-module triggering (e.g., MTU timer → A/D conversion start) while the CPU remains in deep sleep. The Multi-function Pin Controller (MPC) allows dynamic assignment of functions-including SCI, RIIC, RSPI, REMC, and CTSU-to shared pins, supporting flexible board layout and feature scalability.
