Renesas R5F51104ADFM#30

Overview

R5F51104ADFM#30 from Renesas is a 32-bit RX CPU core microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 12-bit A/D converter with 14 channels, RTC, and dual SCI + I²C + RSPI interfaces. It targets low-power industrial sensor nodes and battery-powered control modules requiring deterministic real-time response and IEC 60730 compliance.

For engineers reviewing the R5F51104ADFM#30 datasheet, R5F51104ADFM#30 pinout, R5F51104ADFM#30 application, or R5F51104ADFM#30 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LFQFP, 10 × 10 mm, 0.5 mm pitch), functional pin roles, and validated alternative parts for design-in and supply continuity.

Technical Context

The R5F51104ADFM#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instruction encoding, enabling ultra-compact code density. Its on-chip peripherals include a 14-channel 12-bit A/D converter with 1.0 µs minimum conversion time, MTU2 timer unit with four 16-bit channels supporting input capture and phase counting, and independent watchdog timer driven by a dedicated 15 kHz on-chip oscillator.

It integrates clock generation with multiple oscillators: high-speed on-chip (32 MHz ±1% over −40 to +85°C), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz). The MCU supports three low-power modes-sleep, deep sleep, and software standby-with 0.35 µA standby current and 4.8 µs wake-up latency, meeting IEC 60730 Class B requirements via CAC, RAM test assist, and IWDT.
