Overview
R5F51306ADFM#30 from Renesas is a 32-bit RX CPU-based microcontroller in the RX130 Group, operating at up to 32 MHz (50 DMIPS), featuring 256 KB on-chip flash, 32 KB SRAM, 8 KB data flash, and integrated capacitive touch sensing (32 channels). It supports IEC60730-compliant safety functions and targets low-power industrial and consumer control applications with integrated A/D, D/A, RTC, and multiple communication interfaces.
For engineers reviewing the R5F51306ADFM#30 datasheet, R5F51306ADFM#30 pinout, R5F51306ADFM#30 application, or R5F51306ADFM#30 equivalent, key selection criteria include its 64-pin LFQFP (PLQP0064KB-C) package, 1.8–5.5 V single-supply operation, software standby current of 0.37 µA, 12-bit A/D converter with 14 input channels, and dual 8-bit D/A outputs - all validated for use in touch-enabled appliance HMI, motor control feedback, and battery-powered sensor nodes.
Technical Context
The R5F51306ADFM#30 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions, delivering 50 DMIPS at 32 MHz. Its memory subsystem includes no-wait 256 KB flash (programmable at 1.8 V), 32 KB SRAM, and 8 KB data flash rated for 1M program/erase cycles with background operation support.
Peripherals are orchestrated via the Event Link Controller (ELC), enabling interrupt-free module triggering and linked operation during CPU sleep. The MCU integrates a 12-bit A/D converter (14 channels, 1.4 µs conversion), two 8-bit D/A channels, RTC with calendar mode, independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, and capacitive touch sensing unit (CTSU) supporting up to 32 keys in self-capacitance mode.

The R5F51306ADFM#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance using its 32-bit RX CPU core. This performance level supports real-time control tasks such as motor commutation, capacitive touch scanning, and sensor fusion algorithms within tight timing constraints. The R5F51306ADFM#30 achieves this with a 5-stage pipeline and variable-length instruction set optimized for code density and execution speed.
Does the R5F51306ADFM#30 support IEC60730 functional safety compliance?
Yes, the R5F51306ADFM#30 includes hardware-assisted features for IEC60730 Class B compliance, including self-diagnostic routines for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance via the data operation circuit (DOC), and analog input disconnection detection. These capabilities are documented in the R5F51306ADFM#30 datasheet and enable certified safety monitoring without external components.
How many capacitive touch channels does the R5F51306ADFM#30 support, and what configuration is used?
The R5F51306ADFM#30 supports up to 32 capacitive touch sensing channels using its integrated CTSU in self-capacitance mode. These channels map to dedicated TS0–TS31 pins and are configured via firmware to detect button presses, sliders, or proximity events with built-in noise filtering. The R5F51306ADFM#30 does not support mutual capacitance mode in the 64-pin PLQP0064KB-C package - that capability is reserved for larger packages with more CTSU pins.
What are the memory resources available on the R5F51306ADFM#30?
The R5F51306ADFM#30 includes 256 KB of on-chip flash memory (no wait states up to 32 MHz), 32 KB of SRAM, and 8 KB of data flash rated for 1,000,000 program/erase cycles with background operation (BGO) support. The flash is programmable at 1.8 V, enabling in-system updates from low-voltage battery sources. All memory blocks operate without wait states, ensuring deterministic timing for real-time applications running on the R5F51306ADFM#30.
Which package type and pin count does the R5F51306ADFM#30 use?
The R5F51306ADFM#30 uses the PLQP0064KB-C package: a 64-pin Low-Profile Quad Flat Package measuring 10 mm × 10 mm with 0.5 mm pitch. This RoHS-compliant, lead-free package supports surface-mount assembly and provides access to 32 CTSU channels, 14 A/D inputs, dual D/A outputs, and full peripheral routing including SCI, I²C, RSPI, and MTU2 PWM outputs - all verified in the R5F51306ADFM#30 pin assignment documentation.
