Product details
Overview
R5F51306BDFK#10 from Renesas Electronics is a 32-bit RX130 Group microcontroller with 256 KB flash, 32 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), featuring a 12-bit A/D converter (14 channels), two 8-bit D/A outputs, capacitive touch sensing (32 channels), RTC, and IEC60730-compliant safety functions for industrial control panels and appliance HMI systems.
For engineers reviewing the R5F51306BDFK#10 datasheet, R5F51306BDFK#10 pinout, R5F51306BDFK#10 application, or R5F51306BDFK#10 equivalent, key selection criteria include its LQFP-64 (PLQP0064GA-A) package, –40°C to +85°C temperature grade, integrated CTSU with mutual capacitance support, dual SCI/I²C/RSPI communication, and low-power software standby mode (0.37 µA).
Technical Context
The R5F51306BDFK#10 implements the 32-bit RX CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling 1-instruction-per-cycle execution and 64-bit accumulator support for motor control math. It integrates an Event Link Controller (ELC) enabling interrupt-free peripheral chaining and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 47 event sources.
Its clock system includes a 32 MHz ±1% high-speed on-chip oscillator, sub-clock (32.768 kHz) for RTC, and PLL with 4–8 MHz input range. Power management features three low-power modes, including software standby with 4.8 µs wake-up and active LPT operation using sub-clock or IWDTCLK.

Its 32-bit RX CPU core features a 5-stage pipeline, variable-length instruction set, and 64-bit accumulator-enabling efficient execution of motor control algorithms and real-time signal processing tasks within the R5F51306BDFK#10's resource constraints.
Does the R5F51306BDFK#10 support capacitive touch sensing, and how many keys can it handle?
Yes, the R5F51306BDFK#10 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 32 keys in mutual capacitance mode using a 36-pin matrix configuration. This capability is confirmed for the PLQP0064GA-A (64-pin LQFP) package variant per Table 1.2 in the datasheet, making the R5F51306BDFK#10 suitable for touch sliders, buttons, and proximity interfaces in consumer and industrial HMIs.
What are the memory resources available on the R5F51306BDFK#10?
The R5F51306BDFK#10 includes 256 KB of on-chip flash memory (with zero wait states at 32 MHz), 32 KB of SRAM (no wait states), and 8 KB of data flash rated for 1,000,000 program/erase cycles.
