Product details
Overview
R5F51303ADFL#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 64 KB flash, 10 KB SRAM, 8 KB data flash, a 12-bit A/D converter (10 channels), two 8-bit D/A channels, capacitive touch sensing (24 keys), and supports IEC60730 safety compliance. It targets battery-powered appliances, smart home sensors, and human-interface modules.
For engineers reviewing the R5F51303ADFL#10 datasheet, R5F51303ADFL#10 pinout, R5F51303ADFL#10 application, or R5F51303ADFL#10 equivalent, key selection criteria include its 48-pin LFQFP (PLQP0048KB-B) package, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 4.8 µs wake-up time, and integrated CTSU with self-capacitance support for up to 24 touch keys.
Technical Context
The R5F51303ADFL#10 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and 50 DMIPS at 32 MHz. Its on-chip peripherals include a 12-bit A/D converter with 1.4 µs conversion time per channel, dual 8-bit D/A outputs, and a 24-channel capacitive touch sensing unit (CTSU) supporting self-capacitance mode only in this 48-pin variant.
Power management includes three low-power modes (sleep, deep sleep, software standby), a dedicated 15 kHz IWDT oscillator, and a low-power timer (LPT) running off the 32.768 kHz sub-clock. Clock generation supports main (1–20 MHz), sub (32.768 kHz), and on-chip oscillators (4 MHz HOCO, 32 MHz ±1% HOCO, 15 kHz IWDTCLK), with CAC for frequency accuracy monitoring.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51303ADFL#10?
The R5F51303ADFL#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 on-chip multiplier/divider enable efficient execution of real-time control algorithms. The R5F51303ADFL#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.
How many capacitive touch channels does the R5F51303ADFL#10 support, and what configuration is available?
The R5F51303ADFL#10 supports exactly 24 capacitive touch sensing (CTSU) channels, implemented exclusively in self-capacitance mode. This matches the 48-pin PLQP0048KB-B package's I/O count (TS0–TS23), with TS24–TS35 unconnected. Mutual capacitance matrix operation is not supported in this variant, as confirmed by Table 1.2 in the RX130 datasheet. The R5F51303ADFL#10 uses these pins for single-key-per-pin detection in applications like control panels and proximity sensors.
Does the R5F51303ADFL#10 include hardware support for functional safety standards such as IEC60730?
Yes, the R5F51303ADFL#10 includes dedicated hardware features for IEC60730 Class B compliance, including a clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test assistance via the data operation circuit (DOC), and A/D converter self-diagnostic and analog input disconnection detection. These capabilities are documented in the "Useful functions for IEC60730 compliance" section of the R5F51303ADFL#10 datasheet and require no external components to implement required safety checks.
What are the memory resources available on the R5F51303ADFL#10?
The R5F51303ADFL#10 integrates 64 KB of on-chip flash memory for program code, 10 KB of SRAM for runtime variables and stack, and 8 KB of data flash rated for 1,000,000 program/erase cycles. All memory blocks operate with zero wait states at maximum CPU speed. The R5F51303ADFL#10 supports background operation (BGO) for data flash, allowing concurrent code execution and non-volatile parameter updates-a key advantage for field-upgradable embedded systems.
What low-power modes and current consumption values are specified for the R5F51303ADFL#10?
The R5F51303ADFL#10 supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws just 0.37 µA (typical) while retaining SRAM content and enabling wake-up via LPT, RTC, or external interrupt. Recovery time from software standby is 4.8 µs. High-speed operating mode consumes 96 µA/MHz, making the R5F51303ADFL#10 suitable for energy-constrained applications such as battery-powered sensors and portable medical devices.
