Product details
Overview
R5F51307ADFL#10 from Renesas Electronics is a 32-bit RX CPU-based microcontroller targeting low-power, touch-enabled consumer and industrial 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 DACs, 12-bit ADC with 17 channels, capacitive touch sensing (24-key support), and real-time clock - all supplied from a single 1.8–5.5 V rail.
For engineers reviewing the R5F51307ADFL#10 datasheet, R5F51307ADFL#10 pinout, R5F51307ADFL#10 application, or R5F51307ADFL#10 equivalent, this page delivers verified functional scope, package-specific peripheral availability, low-power mode timing, and validated alternative options for design-in and supply continuity planning.
Technical Context
The R5F51307ADFL#10 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-bit multiply. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and dedicated IWDT oscillator (15 kHz), with independent ICLK/PCLK/FCLK domains.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables inter-module triggering without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers triggered by 47 event sources. The 48-pin LFQFP package (PLQP0048KB-B) provides 38 GPIOs, excludes REMC and RTC, and limits A/D to 10 channels versus higher-pin-count variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51307ADNE#U0 | Same core, memory, and peripherals but in 48-pin HWQFN (PWQN0048KB-A) package - smaller footprint (5×5 mm), exposed thermal pad, no leaded pins | Better thermal performance and PCB space efficiency; requires reflow-compatible layout; lacks 5-V-tolerant I/O pins present in LFQFP variant | Select for space-constrained, thermally demanding designs where lead-free assembly is standard and 5-V tolerance is unnecessary. |
| R5F51305ADFL#30 | Same 48-pin LFQFP package but reduced memory: 128 KB flash / 16 KB SRAM / 8 KB data flash; same peripheral set except CTSU limited to 24 keys | Lowers cost and power in simpler UI or sensor nodes where code size <128 KB and RAM <16 KB suffice | Choose when application firmware fits within 128 KB and no future feature expansion is planned - ideal for high-volume cost-sensitive appliances. |
Compared with R5F51307ADFL#10, R5F51307ADNE#U0 offers superior thermal dissipation in compact layouts but sacrifices 5-V I/O tolerance, while R5F51305ADFL#30 reduces memory capacity by 73% to lower unit cost - both retain identical peripheral functionality and pin-compatible I/O mapping within their respective packages.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51307ADFL#10?
The R5F51307ADFL#10 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance using the 32-bit RXv1 CPU core. Its zero-wait-state flash memory and single-cycle 32×32-bit multiply unit enable deterministic real-time execution. This performance level supports responsive touch UIs and concurrent sensor processing without external co-processors.
How many analog-to-digital converter channels does the R5F51307ADFL#10 support, and what is its conversion speed?
The R5F51307ADFL#10 supports 10 channels of 12-bit analog-to-digital conversion, consistent with its 48-pin LFQFP package limitation (Table 1.2). Each conversion completes in as little as 1.4 µs when ADCLK runs at 32 MHz - enabling sampling rates exceeding 700 kSPS across active channels for fast-response sensor systems.
Does the R5F51307ADFL#10 include capacitive touch sensing, and how many keys does it support?
Yes, the R5F51307ADFL#10 integrates the Capacitive Touch Sensing Unit (CTSU) and supports up to 24 keys in self-capacitance mode - matching the pin count and CTSU channel allocation for the PLQP0048KB-B package. This eliminates external touch controllers in appliance control panels and thermostats while maintaining noise immunity via hardware-accelerated correlation processing.
What low-power modes are available on the R5F51307ADFL#10, and what is its standby current?
The R5F51307ADFL#10 offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode - where only the low-power timer (LPT) and reset circuit remain active - supply current drops to 0.37 µA. Recovery to full operation takes just 4.8 µs, making it suitable for battery-powered devices requiring frequent wake-up intervals.
Is the R5F51307ADFL#10 pin-compatible with other RX130 Group MCUs in the same package?
Yes, the R5F51307ADFL#10 shares identical pinout and electrical characteristics with other RX130 Group devices in the PLQP0048KB-B package (e.g., R5F51305ADFL#30, R5F51306BDFL#30), enabling memory-size-based scalability without PCB redesign. All 48-pin variants use the same mechanical footprint, thermal pad configuration, and I/O function mapping per Table 1.4.
