Product details
Overview
R5F51303ADFK#10 from Renesas Electronics 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 64 KB flash, 10 KB SRAM, 8 KB data flash, dual 8-bit D/A converters, 12-bit A/D converter with 14 channels, capacitive touch sensing (32 channels), and supports IEC60730 functional safety compliance.
For engineers reviewing the R5F51303ADFK#10 datasheet, R5F51303ADFK#10 pinout, R5F51303ADFK#10 application, or R5F51303ADFK#10 equivalent, key selection criteria include its LQFP-64 (PLQP0064GA-A, 14×14 mm, 0.8 mm pitch) package, –40°C to +85°C temperature grade, 1.8–5.5 V single-supply operation, and integrated RTC, ELC, and CTSU for battery-powered HMI and appliance control.
Technical Context
The R5F51303ADFK#10 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and 1-instruction-per-cycle execution for critical real-time tasks. Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for accuracy monitoring.
Peripheral integration centers on event-driven operation: the Event Link Controller (ELC) enables interrupt-free inter-module triggering (e.g., MTU → A/D start), while the Data Transfer Controller (DTC) supports chain transfers across 47 event sources. The capacitive touch sensing unit (CTSU) uses mutual capacitance for up to 32 keys in matrix configuration on this 64-pin variant.

FAQ
What is the maximum operating frequency and CPU performance of the R5F51303ADFK#10?
The R5F51303ADFK#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 execution for many instructions enable deterministic real-time response in control applications. This performance level is sustained across the full 1.8–5.5 V supply range.
Does the R5F51303ADFK#10 support IEC60730 Class B compliance?
Yes, the R5F51303ADFK#10 includes hardware-assisted IEC60730 Class B compliance features: A/D converter self-test, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) diagnostics, RAM test support via the Data Operation Circuit (DOC), and analog input disconnection detection. These are documented in the RX130 Group hardware manual and supported by Renesas application notes.
What capacitive touch capability does the R5F51303ADFK#10 provide?
The R5F51303ADFK#10 integrates the CTSUa module supporting up to 32 keys using mutual capacitance matrix configuration (TS0–TS31). Unlike self-capacitance implementations, this method provides superior noise immunity and multi-touch capability. No external RC networks or dedicated touch controller ICs are required, reducing BOM cost and PCB area.
Which communication interfaces are available on the R5F51303ADFK#10?
The R5F51303ADFK#10 provides seven SCI channels (SCI0,1,5,6,8,9,12), one I²C bus interface (RIIC0), and one serial peripheral interface (RSPIA). SCI supports asynchronous, clock-synchronous, I²C, SPI, and LIN modes; RIIC runs at up to 400 kbps; RSPIA supports master/slave operation with 32-bit frame lengths and double buffering for efficient data streaming.
What is the package type and pin count of the R5F51303ADFK#10?
The R5F51303ADFK#10 uses the PLQP0064GA-A package: a 64-pin LQFP with 14 × 14 mm body size and 0.8 mm pin pitch. This package differs from the 0.5 mm pitch LFQFP variants (e.g., PLQP0064KB-C) and includes RTC and REMC functionality absent in some other 64-pin RX130 options.
