Renesas R5F51307ADFP#30

Overview

R5F51307ADFP#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller designed for low-power, touch-enabled embedded control applications. It operates at up to 32 MHz (50 DMIPS), integrates 384 KB on-chip flash, 48 KB SRAM, 8 KB data flash, dual 8-bit D/A converters, 12-bit A/D converter with 17 channels, capacitive touch sensing unit (36 channels), RTC, and supports IEC60730 safety compliance. It targets appliance control panels and industrial HMI interfaces requiring robust timing, analog sensing, and capacitive touch.

For engineers reviewing the R5F51307ADFP#30 datasheet, R5F51307ADFP#30 pinout, R5F51307ADFP#30 application, or R5F51307ADFP#30 equivalent, this page delivers verified specifications, package mapping to PLQP0100KB-B (100-pin LFQFP), validated pin functions, real-world use cases, and two confirmed alternative parts with documented technical and application differences.

Technical Context

The R5F51307ADFP#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle 32×32 multiply operations. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and dedicated IWDT oscillator (15 kHz), all managed via independent clock domains (ICLK, PCLKB, FCLK).

Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables direct module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 47 event sources. The capacitive touch sensing unit (CTSUa) supports both self- and mutual-capacitance modes, with hardware-accelerated noise rejection and 36-channel scan capability.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51307ADFP#30?

The R5F51307ADFP#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance using the 32-bit RXv1 CPU core. Its architecture supports single-cycle 32×32 multiplication, 64-bit accumulator results, and fast interrupt response-making it suitable for real-time control tasks such as motor commutation and capacitive touch scanning without external co-processors.

Does the R5F51307ADFP#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F51307ADFP#30 includes hardware-assisted features for IEC60730 Class B compliance, including RAM test support via the Data Operation Circuit (DOC), A/D converter self-diagnostic and analog input disconnection detection, clock frequency accuracy measurement (CAC), and independent watchdog timer (IWDT) with dedicated oscillator. These reduce software certification burden and enable safer operation in household appliances.

What package type and pin count does the R5F51307ADFP#30 use?

The R5F51307ADFP#30 uses the PLQP0100KB-B package: a 100-pin Low-Profile Quad Flat Package measuring 14 mm × 14 mm with 0.5 mm pitch and an exposed thermal pad. This package provides full access to all peripherals-including 36 CTSU channels, 17 A/D inputs, 6 SCI channels, and 24 GPIOs-making it the highest I/O variant in the RX130 Group.

Can the R5F51307ADFP#30 operate from a single 3.3 V supply?

Yes, the R5F51307ADFP#30 supports a wide operating voltage range of 1.8 V to 5.5 V. At 3.3 V, it runs at its maximum 32 MHz frequency, enabling full peripheral operation-including 12-bit A/D conversion, capacitive touch sensing, and SCI communication-without level-shifting circuitry. Its 5-V-tolerant GPIOs also simplify interfacing with legacy 5 V sensors or displays.

How many capacitive touch channels are supported by the R5F51307ADFP#30?

The R5F51307ADFP#30 supports up to 36 capacitive touch sensing channels via its integrated CTSUa peripheral. In the 100-pin PLQP0100KB-B package, all 36 TSx pins (TS0–TS35) are physically available, enabling implementation of full QWERTY keypads, multi-zone sliders, or proximity-sensing surfaces without external touch controller ICs.
