Product details
Overview
R5F51308AGFK#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller with 512 KB flash, 48 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), featuring integrated 12-bit A/D, dual 8-bit D/A, capacitive touch sensing (32 channels), RTC, and IEC60730 compliance for industrial safety-critical applications.
For engineers reviewing the R5F51308AGFK#30 datasheet, R5F51308AGFK#30 pinout, R5F51308AGFK#30 application, or R5F51308AGFK#30 equivalent, this MCU supports low-power operation down to 0.37 µA in software standby mode, includes ELC for event-driven peripheral coordination without CPU wake-up, and delivers 1.4 µs A/D conversion time - key selection criteria for battery-powered HMI and motor control systems.
Technical Context
The R5F51308AGFK#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a dedicated clock frequency accuracy measurement circuit (CAC) and independent watchdog timer (IWDT) with 15 kHz on-chip oscillator - both required for IEC60730 Class B self-test compliance.
Its event link controller (ELC) enables direct hardware-level triggering between 47 event sources and peripherals (e.g., MTU → A/D start), eliminating interrupt latency and CPU overhead. The multi-function pin controller (MPC) allows dynamic reassignment of functions like SCI, I²C, or CTSU across multiple pins, supporting flexible PCB layout and feature differentiation across product variants.
