Product details
Overview
R5F51308ADFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 512 KB on-chip flash, 48 KB SRAM, 8 KB data flash, 12-bit A/D converter (17 channels), two 8-bit D/A outputs, capacitive touch sensing (32 channels), and IEC60730-compliant safety functions for industrial control and consumer HMI applications.
For engineers reviewing the R5F51308ADFM#30 datasheet, R5F51308ADFM#30 pinout, R5F51308ADFM#30 application, or R5F51308ADFM#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, 4.8 µs wake-up time, and integrated RTC with calendar mode.
Technical Context
The R5F51308ADFM#30 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code and single-cycle 32×32-bit multiplication. It integrates an Event Link Controller (ELC) that enables inter-module triggering without CPU intervention, supporting low-power synchronized peripheral operation during sleep.
Its clock system includes a 32 MHz ±1% high-speed on-chip oscillator, PLL (4–8 MHz input), sub-clock (32.768 kHz), and Clock Accuracy Measurement (CAC) circuit. The MCU supports three low-power modes-sleep, deep sleep, and software standby-with LPT running in standby and IWDT driven by a dedicated 15 kHz oscillator.

Its 5-stage pipeline, single-cycle 32×32-bit multiply, and ultra-compact instruction set enable efficient code execution. The MCU sustains full-speed operation with zero wait states on its 512 KB flash memory, achieving a 31.25 ns read cycle time at 32 MHz.
Does the R5F51308ADFM#30 support IEC60730 functional safety compliance?
Yes, the R5F51308ADFM#30 includes hardware-assisted features for IEC60730 Class B compliance, including A/D converter self-diagnostic, clock frequency accuracy measurement (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test support via Data Operation Circuit (DOC), and analog input disconnection detection. These features reduce software validation burden and support systematic fault coverage in safety-critical home and industrial appliances.
What are the capacitive touch capabilities of the R5F51308ADFM#30?
The R5F51308ADFM#30 integrates a Capacitive Touch Sensing Unit (CTSUa) supporting up to 32 channels in mutual capacitance mode (matrix configuration) or 36 keys in self-capacitance mode. It provides noise immunity tuning, proximity detection, and automatic calibration-enabling robust touch interfaces without external controllers. The TS0–TS31 pins are dedicated to touch sensing, and TSCAP requires a 10 nF decoupling capacitor to VSS.
What low-power modes does the R5F51308ADFM#30 support, and what is its standby current?
The R5F51308ADFM#30 supports three low-power modes: sleep, deep sleep, and software standby. In software standby mode, it draws only 0.37 µA while maintaining RTC and LPT operation. Wake-up occurs in 4.8 µs via external interrupt, LPT match, or RTC alarm. The MCU also features a low-power timer (LPT) that runs independently on sub-clock or IWDTCLK during standby, enabling precise periodic wake-up scheduling.
What communication interfaces are integrated into the R5F51308ADFM#30?
The R5F51308ADFM#30 integrates six serial communication channels: six SCIg (SCI0,1,5,6,8,9) and one SCIh (SCI12), one I²C bus interface (RIICa), and one RSPI channel.
