Product details
Overview
R5F52203BDFP#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (49 DMIPS), featuring 64 KB on-chip flash, 8 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels, 1.56 µs conversion), and integrated RTC with calendar support. It targets industrial control, sensor interface, and IEC60730-compliant appliance applications.
For engineers reviewing the R5F52203BDFP#30 datasheet, R5F52203BDFP#30 pinout, R5F52203BDFP#30 application, or R5F52203BDFP#30 equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C temperature grade, ELC event-driven peripheral activation, MPC pin function remapping, and IEC60730 self-test functions for safety-critical firmware.
Technical Context
The R5F52203BDFP#30 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates main, sub-clock (32.768 kHz), high-speed/low-speed on-chip oscillators, and IWDT-dedicated 125-kHz oscillator with frequency division options.
Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module triggering without CPU intervention-supporting low-power operation during sleep modes. The Multi-function Pin Controller (MPC) allows dynamic assignment of SCI, RSPI, RIIC, MTU, and ADC functions across multiple I/O pins, including 5-V tolerant and open-drain configurations.
