Product details
Overview
R5F51307AGFL#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller optimized for low-power, touch-enabled consumer and industrial control applications. It operates at up to 32 MHz (50 DMIPS), integrates 384 KB flash, 48 KB SRAM, 8 KB data flash, dual 8-bit DACs, 12-bit ADC with 17 channels, capacitive touch sensing (24 keys), RTC, and multiple communication interfaces including SCI, I²C, and RSPI - deployed in compact 48-pin LFQFP (7 × 7 mm, 0.5 mm pitch) for space-constrained designs.
For engineers reviewing the R5F51307AGFL#10 datasheet, R5F51307AGFL#10 pinout, R5F51307AGFL#10 application, or R5F51307AGFL#10 equivalent, key selection considerations include its −40°C to +105°C extended temperature grade, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and integrated IEC60730 safety support functions for certified embedded control.
Technical Context
The R5F51307AGFL#10 implements the 32-bit RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - delivering 50 DMIPS at 32 MHz with 64-bit accumulator support for 32×32 multiply operations in one cycle. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.
Peripheral integration centers on event-driven operation: ELC enables interrupt-free inter-module triggering (e.g., MTU → ADC start), DTC supports four transfer modes with chain capability, and MPC allows flexible pin function assignment. The device supports IEC60730 Class B compliance via built-in self-test aids for ADC, IWDT, RAM, and clock accuracy measurement.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51307AGFL#10?
The R5F51307AGFL#10 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance using the 32-bit RXv1 CPU core. Its 5-stage pipeline, variable-length instruction set, and single-cycle 32×32 multiply capability enable efficient real-time control. The R5F51307AGFL#10 achieves this performance across its full 1.8–5.5 V supply range, with frequency scaling tied to VCC voltage levels per datasheet specifications.
Does the R5F51307AGFL#10 support IEC60730 Class B compliance out of the box?
The R5F51307AGFL#10 includes dedicated hardware features to assist IEC60730 Class B compliance, including self-diagnostic functions for the ADC, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), and RAM test support via the Data Operation Circuit (DOC). While these features reduce implementation effort, full compliance requires proper software integration and system-level validation - the R5F51307AGFL#10 provides the foundational hardware capabilities needed.
What are the key differences between R5F51307AGFL#10 and R5F51307ADFL#30?
The R5F51307AGFL#10 and R5F51307ADFL#30 share identical package (48-pin LFQFP), pinout, memory (384 KB flash, 48 KB SRAM), peripherals, and electrical characteristics - differing only in operating temperature grade: R5F51307AGFL#10 is rated for −40°C to +105°C, while R5F51307ADFL#30 is rated for −40°C to +85°C. Both use the same chip version B silicon.
How many capacitive touch keys does the R5F51307AGFL#10 support, and what configuration is used?
The R5F51307AGFL#10 supports up to 24 capacitive touch keys using the self-capacitance method, mapped to dedicated TS0–TS23 pins. This configuration requires one pin per key and is optimized for button, slider, and proximity sensing in consumer interfaces. The CTSU hardware includes noise suppression and automatic calibration - the R5F51307AGFL#10 does not support mutual capacitance mode in the 48-pin variant.
What low-power modes are available on the R5F51307AGFL#10, and what is the lowest achievable current draw?
The R5F51307AGFL#10 offers three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode - where only the LPT, RTC, and IWDT remain active - the device draws just 0.37 µA (typical) at 3.3 V. Wake-up time from this state is 4.8 µs, enabling rapid responsiveness while maintaining ultra-low quiescent power - a key advantage for battery-powered R5F51307AGFL#10 deployments.
