Renesas R5F51307AGFN#30

Overview

R5F51307AGFN#30 from Renesas is a 32-bit RX CPU-based microcontroller with 384 KB flash, 48 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), supporting capacitive touch sensing (36 channels), 12-bit A/D (17 channels), dual 8-bit D/A, RTC, and IEC60730-compliant safety functions for industrial control panels and appliance HMI systems.

For engineers reviewing the R5F51307AGFN#30 datasheet, R5F51307AGFN#30 pinout, R5F51307AGFN#30 application, or R5F51307AGFN#30 equivalent, key selection criteria include its 80-pin LFQFP package, –40°C to +105°C extended temperature rating, integrated CTSU for self-capacitance touch keys, and ELC-driven low-power peripheral coordination without CPU wake-up.

Technical Context

The R5F51307AGFN#30 implements a CISC Harvard architecture with 5-stage pipeline and variable-length instructions, enabling 1-instruction-per-cycle execution at 32 MHz. Its on-chip peripherals are synchronized via independent clock domains: ICLK (system, max 32 MHz), PCLKB (peripherals, max 32 MHz), and FCLK (FlashIF, max 32 MHz).

Event Link Controller (ELC) enables direct hardware-triggered operation between 47 event sources and modules like MTU2, TMR, and A/D converter-allowing timer-triggered conversions and PWM updates while CPU remains in deep sleep mode. The DTC supports chain transfer across four interrupt sources with normal, repeat, and block modes.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51307AGFN#30?

The R5F51307AGFN#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its 32-bit RX CPU core features a 5-stage pipeline, variable-length instruction set, and single-cycle instruction execution capability-enabling deterministic real-time response for industrial control tasks. This performance level is sustained across the full –40°C to +105°C operating range.

Does the R5F51307AGFN#30 support capacitive touch sensing, and how many keys can it handle?

Yes, the R5F51307AGFN#30 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 36 self-capacitance keys using TS0–TS35 pins. In mutual capacitance matrix mode, it supports up to 324 keys with 36 dedicated pins. The CTSU requires no external RC components and includes built-in noise suppression-making it ideal for appliance control panels and industrial HMIs where reliability in noisy environments is critical. The R5F51307AGFN#30's CTSU is fully functional in its 80-pin LFQFP package.

What low-power modes does the R5F51307AGFN#30 offer, and what is its lowest supply current?

The R5F51307AGFN#30 offers three low-power consumption modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode-with Low Power Timer (LPT) active-it draws only 0.37 µA. Wake-up occurs in 4.8 µs, allowing rapid response to touch or sensor events. This ultra-low quiescent current enables battery-powered applications such as smart thermostats to achieve multi-year operation on a single coin cell-without compromising real-time responsiveness.

How much memory does the R5F51307AGFN#30 include, and is background programming supported?

The R5F51307AGFN#30 includes 384 KB of on-chip flash memory for program code, 48 KB of SRAM for runtime data, and 8 KB of data flash rated for 1,000,000 program/erase cycles. Background Operation (BGO) is fully supported for data flash-enabling concurrent firmware execution and non-volatile parameter updates without CPU interruption. This capability is essential for field-upgradable devices like industrial controllers where downtime must be minimized.

What communication interfaces are integrated into the R5F51307AGFN#30?

The R5F51307AGFN#30 integrates up to seven Serial Communications Interface (SCI) channels-including SCIg (6 channels) and SCIh (1 channel with LIN support), one I²C bus interface (RIICa) capable of 400 kbps, one Serial Peripheral Interface (RSPIa) supporting up to 16 Mbps, and one Remote Control Signal Receiver (REMC) with two units. These interfaces support asynchronous, clock-synchronous, I²C, SPI, smart card, and LIN protocols-providing flexible connectivity for displays, sensors, actuators, and wireless modules in complex embedded systems.
