Product details
Overview
R5F51308AGFP#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 KB on-chip flash, 48 KB SRAM, 8 KB data flash, 12-bit A/D converter (24 channels), dual 8-bit D/A outputs, capacitive touch sensing (36 channels), RTC, and IEC60730-compliant safety functions - deployed in industrial HMI and consumer appliance control systems.
For engineers reviewing the R5F51308AGFP#30 datasheet, R5F51308AGFP#30 pinout, R5F51308AGFP#30 application, or R5F51308AGFP#30 equivalent, key selection criteria include extended temperature support (–40°C to +105°C), 100-pin LFQFP package with 5-V-tolerant I/O, integrated remote control signal receiver (REMC), and ELC-driven low-power peripheral coordination without CPU wake-up.
Technical Context
The R5F51308AGFP#30 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle 32×32-bit multiplication. Its event link controller (ELC) enables direct inter-module triggering - e.g., MTU timer events initiating A/D conversion - while the CPU remains in deep sleep mode.
It integrates a dedicated low-speed on-chip oscillator (15 kHz) for independent watchdog timer (IWDT) operation and a clock frequency accuracy measurement circuit (CAC) supporting IEC60730 self-test requirements. The high-speed on-chip oscillator delivers 32 MHz ±1% without external crystal, reducing BOM count in cost-sensitive applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51308ADFP#30 | Same RX130 Group, identical peripherals and pinout, but rated for –40°C to +85°C only | Suitable for commercial-grade appliances without extended thermal requirements | Select when ambient temperature stays below +85°C and cost sensitivity favors standard-grade variant |
| R5F51306BGFP#30 | 256 KB flash / 32 KB RAM / same package; lacks REMC and reduces A/D channels to 24 (same count) but removes some SCI channels | Targeted at cost-optimized industrial controls where IR remote support is unnecessary | Choose when firmware size < 256 KB and REMC functionality is unused - lowers unit cost without layout change |
