Product details
Overview
R5F51103ADFM#10 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 KB on-chip flash, 10 KB SRAM, 12-bit A/D converter with 14 channels, RTC, and dual SCI + I²C + RSPI interfaces. It targets low-power industrial sensing and control applications requiring deterministic real-time response and IEC 60730 compliance.
For engineers reviewing the R5F51103ADFM#10 datasheet, R5F51103ADFM#10 pinout, R5F51103ADFM#10 application, or R5F51103ADFM#10 equivalent, this page delivers verified specifications, package mapping, functional pin roles, and validated alternative options for embedded design and BOM optimization.
Technical Context
The R5F51103ADFM#10 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its 32-bit × 32-bit multiplier delivers 64-bit results in one cycle, and the accumulator supports DSP operations including 9 dedicated DSP instructions.
It integrates a clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) driven by a dedicated 15 kHz oscillator, and hardware-assisted RAM testing functions - all aligned with IEC 60730 Class B safety requirements. The MTU2 timer unit provides four 16-bit channels with phase counting and input capture, while the DTC enables chain transfer triggered by 65 interrupt sources.
