Product details
Overview
R5F51307ADFL#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller in the RX130 Group, operating at up to 32 MHz (50 DMIPS), featuring 384 KB on-chip flash, 48 KB SRAM, 8 KB data flash, 12-bit A/D converter (10 channels), two 8-bit D/A outputs, capacitive touch sensing (24 keys), and IEC60730-compliant safety functions - deployed in industrial human-machine interfaces and consumer appliance control systems.
For engineers reviewing the R5F51307ADFL#30 datasheet, R5F51307ADFL#30 pinout, R5F51307ADFL#30 application, or R5F51307ADFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-B (48-pin LFQFP, 7 × 7 mm, 0.5 mm pitch), functional pin roles, real-world use cases, and validated alternative parts for design continuity and sourcing flexibility.
Technical Context
The R5F51307ADFL#30 implements a CISC Harvard-architecture RX core with 5-stage pipeline, 64-bit accumulator, and single-cycle 32×32 multiply. Its clock system integrates HOCO (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for accuracy monitoring - all configurable via ICLK/PCLK/FCLK domains.
Peripheral integration includes ELC for event-driven module activation without CPU wake-up, DTC for interrupt-triggered transfers, MTU2 (6-channel 16-bit timer) with complementary PWM and phase counting, and CTSU supporting self-capacitance up to 24 keys - all optimized for low-power operation across sleep, deep sleep, and software standby modes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51307ADNE#U0 | Same core, memory, and peripherals; HWQFN-48 (7 × 7 mm, 0.5 mm pitch) with wettable flanks - superior thermal performance and automated optical inspection (AOI) compatibility. | Better suited for high-volume, reflow-soldered consumer products requiring compact footprint and enhanced thermal dissipation. | Select when PCB assembly uses AOI or thermal management exceeds LFQFP limits; pinout differs - requires layout revision. |
| R5F51305ADFL#30 | Lower memory: 128 KB flash / 16 KB SRAM; same 48-pin LFQFP package and peripheral set - reduced cost and code space for simpler applications. | Ideal for cost-sensitive, function-limited devices like basic remote controls or sensor nodes where full 384 KB flash is unused. | Choose when firmware size remains under 100 KB and no future feature expansion is planned - identical pinout enables drop-in replacement. |
