For engineers reviewing the R5F51307AGFP#30 datasheet, R5F51307AGFP#30 pinout, R5F51307AGFP#30 application, or R5F51307AGFP#30 equivalent, key selection criteria include its 100-pin LFQFP package, –40°C to +105°C extended temperature rating, integrated CTSU for touch interfaces, and support for event-driven low-power operation via ELC and LPT.

Technical Context

The R5F51307AGFP#30 implements a CISC Harvard-architecture RX core with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply operations. It integrates an Event Link Controller (ELC) enabling direct inter-module triggering without CPU intervention and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 47 event sources.

Its clock system includes high-speed (32 MHz ±1%) and low-speed (15 kHz) on-chip oscillators, PLL, sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit. Power management features three low-power modes, including software standby with 0.37 µA supply current and 4.8 µs wake-up time, sustained by the Low Power Timer (LPT) running off sub-clock or IWDTCLK.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51307AGFP#30?

The R5F51307AGFP#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RX CPU core supports single-cycle 32×32-bit multiplication with a 64-bit accumulator, enabling efficient motor control and real-time signal processing. The R5F51307AGFP#30 achieves this performance across its full operating voltage range (1.8–5.5 V) with no wait states on flash access.

Does the R5F51307AGFP#30 support IEC60730 functional safety compliance?

Yes, the R5F51307AGFP#30 includes hardware-assisted self-diagnostic features required for Class B IEC60730 compliance, including A/D converter self-test, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT), RAM test support via DOC, and analog input disconnection detection. These capabilities are documented in the device's safety manual and reduce software validation burden for appliance manufacturers. The R5F51307AGFP#30 is qualified for use in safety-critical household and industrial control applications.

What package type and pin count does the R5F51307AGFP#30 use?

The R5F51307AGFP#30 uses a 100-pin LFQFP package designated PLQP0100KB-B, measuring 14 mm × 14 mm with 0.5 mm pitch and an exposed thermal pad. This package supports full peripheral availability including all 36 CTSU channels, 17 A/D inputs, six MTU channels, seven SCI interfaces, and dual D/A outputs. The R5F51307AGFP#30 is pin-compatible with other RX130 Group 100-pin variants such as R5F51308AGFP#30 and R5F51306BGFP#30.

How many capacitive touch channels does the R5F51307AGFP#30 support, and what configurations are available?

The R5F51307AGFP#30 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 36 self-capacitance keys or up to 324 mutual-capacitance keys in matrix configuration. It uses TS0–TS35 pins for electrode connection and TSCAP for stabilization. The CTSU includes hardware noise cancellation and automatic drift compensation. This capability is fully enabled in the 100-pin package. The R5F51307AGFP#30 does not require external touch controller ICs for mainstream HMI implementations.

What are the low-power operation capabilities of the R5F51307AGFP#30?

The R5F51307AGFP#30 offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.37 µA while maintaining RTC and LPT operation - with wake-up in 4.8 µs. The LPT can run from sub-clock or IWDTCLK, enabling precise periodic wake-up without external components. The R5F51307AGFP#30 also supports dynamic voltage/frequency scaling and module stop control to minimize active-mode current to 96 µA/MHz.
