Overview
R5F51303AGFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 64 KB on-chip flash, 10 KB SRAM, 8 KB data flash, 12-bit A/D converter (17 channels), two 8-bit D/A outputs, capacitive touch sensing (32 keys), and IEC60730-compliant safety functions for industrial control applications.
For engineers reviewing the R5F51303AGFM#30 datasheet, R5F51303AGFM#30 pinout, R5F51303AGFM#30 application, or R5F51303AGFM#30 equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-C) package, –40°C to +105°C temperature grade, integrated RTC (binary/calendar mode), low-power software standby (0.37 µA), and ELC-driven event-linked peripheral operation without CPU wake-up.
Technical Context
The R5F51303AGFM#30 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiply-accumulate operations. Its clock system integrates HOCO (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and IWDT-dedicated 15 kHz oscillator, with independent ICLK/PCLK/FCLK domains enabling precise power/performance tuning.
Peripheral coordination is managed via Event Link Controller (ELC), supporting 47 event sources and enabling linked module operation during CPU sleep. The Data Transfer Controller (DTC) provides four transfer modes with chain capability, while Multi-function Pin Controller (MPC) allows flexible I/O function assignment across 52 GPIOs in its 64-pin configuration.

Does the R5F51303AGFM#30 support capacitive touch sensing, and how many keys are available in its 64-pin package?
Yes, the R5F51303AGFM#30 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 32 keys in the 64-pin PLQP0064KB-C package using self-capacitance mode. It requires no external touch controller, reducing BOM cost and PCB area. The R5F51303AGFM#30's CTSU also supports mutual capacitance for matrix configurations, though 32-key self-capacitance is the validated limit for this pin count.
What low-power modes does the R5F51303AGFM#30 offer, and what is its lowest supply current?
The R5F51303AGFM#30 supports three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode-with Low Power Timer (LPT) active-it draws just 0.37 µA. Recovery time from this state is 4.8 µs, enabling rapid response to external events. This ultra-low quiescent current makes the R5F51303AGFM#30 well-suited for battery-backed or energy-harvesting applications.
