Product details
Overview
R5F51103AGNE#20 from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 Kbytes of on-chip flash memory, 10 Kbytes of SRAM, and integrated peripherals including a 12-bit A/D converter (14 channels), RTC, dual SCI interfaces, I²C, RSPI, MTU2 timers, and independent watchdog timer. It targets low-power embedded control in industrial sensors and battery-powered IoT edge nodes.
For engineers reviewing the R5F51103AGNE#20 datasheet, R5F51103AGNE#20 pinout, R5F51103AGNE#20 application, or R5F51103AGNE#20 equivalent, this page delivers verified specifications, package mapping to PWQN0048KB-A (48-pin HWQFN, 7 × 7 mm, 0.5 mm pitch), functional pin roles, real-world use cases, and validated alternative parts for design-in decisions.
Technical Context
The R5F51103AGNE#20 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its on-chip clock generation includes high-speed (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) oscillators, plus a clock frequency accuracy measurement circuit (CAC) for IEC 60730 compliance.
It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 65 interrupt vectors, and features a multi-function timer pulse unit (MTU2) with four 16-bit channels supporting input capture, output compare, phase counting, and A/D trigger generation - all synchronized to PCLK up to 32 MHz.
