Product details
Overview
R5F51308AGFL#10 from Renesas is a 32-bit RX CPU-based microcontroller designed for low-power, touch-enabled consumer and industrial control applications. It operates at up to 32 MHz (50 DMIPS), integrates 512 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 supports IEC60730 safety compliance.
For engineers reviewing the R5F51308AGFL#10 datasheet, R5F51308AGFL#10 pinout, R5F51308AGFL#10 application, or R5F51308AGFL#10 equivalent, this page delivers verified specifications, package mapping, functional context, and real-world use cases - all aligned to the RX130 Group's documented capabilities for the 48-pin LFQFP (PLQP0048KB-B) variant.
Technical Context
The R5F51308AGFL#10 implements the 32-bit RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling 50 DMIPS at 32 MHz. It features on-chip clock generation including HOCO (32 MHz ±1%), sub-clock oscillator (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.
Its peripheral set is tailored for embedded control: ELC enables event-driven module operation without CPU intervention; DTC supports four transfer modes with interrupt-triggered chaining; and the CTSU supports self-capacitance touch sensing across 24 pins - consistent with the 48-pin package's functional subset per Table 1.2.

FAQ
What is the maximum operating frequency of the R5F51308AGFL#10 and under what voltage conditions?
The R5F51308AGFL#10 achieves a maximum operating frequency of 32 MHz when powered at VCC ≥2.7 V. At 2.4–2.7 V, max frequency is 16 MHz; at 1.8–2.4 V, it is limited to 8 MHz. This voltage-frequency scaling ensures reliable operation across wide input ranges while optimizing power efficiency in battery or unregulated supply applications - a key feature confirmed in Section 1.1 of the R01DS0273EJ0300 datasheet.
Does the R5F51308AGFL#10 support capacitive touch sensing, and how many keys are available in its 48-pin package?
Yes, the R5F51308AGFL#10 integrates the Capacitive Touch Sensing Unit (CTSU) and supports 24 touch keys in the 48-pin LFQFP (PLQP0048KB-B) package - as specified in Table 1.2 of the datasheet. This is a subset of the full 36-key capability available in larger packages, with TS0–TS23 assigned as touch electrode pins and TSCAP as the reference capacitor connection point.
What safety features does the R5F51308AGFL#10 provide for IEC60730 compliance?
The R5F51308AGFL#10 includes dedicated hardware-assisted IEC60730 functions: self-diagnostic A/D converter test, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test support via Data Operation Circuit (DOC), and analog input disconnection detection. These are explicitly documented in the "Useful functions for IEC60730 compliance" section of the datasheet and require no external components to implement Class B checks.
What are the memory resources available on the R5F51308AGFL#10?
The R5F51308AGFL#10 provides 512 KB of on-chip flash memory (with zero wait states at 32 MHz), 48 KB of SRAM (also zero wait states), and 8 KB of data flash rated for 1,000,000 program/erase cycles. All memory is accessible via the RX CPU's linear 4 GB address space and supports background operation (BGO) for data flash writes during code execution - as detailed in Tables 1.1 and 1.3 of R01DS0273EJ0300.
Which communication interfaces are supported by the R5F51308AGFL#10 in its 48-pin configuration?
In the 48-pin PLQP0048KB-B package, the R5F51308AGFL#10 supports SCIg (3 channels), SCIh (1 channel), RSPI (1 channel), RIIC (1 channel), and simple I²C/SPI modes - totaling six serial interfaces. Remote control signal reception (REMC) and 64-pin-only peripherals like additional SCI channels or full CTSU are excluded, per Table 1.2. All interfaces operate with configurable clock sources and ELC-triggered transfers.
