Product details
Overview
R5F51307ADFM#30 from Renesas is a 32-bit RX130 Group microcontroller with 384 KB flash, 48 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), featuring integrated 12-bit A/D converter (17 channels), dual 8-bit D/A outputs, capacitive touch sensing (32 keys), RTC, and IEC60730 safety support - deployed in industrial HMI and consumer appliance control systems.
For engineers reviewing the R5F51307ADFM#30 datasheet, R5F51307ADFM#30 pinout, R5F51307ADFM#30 application, or R5F51307ADFM#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, and ELC-driven event-linked peripheral coordination without CPU wake-up.
Technical Context
The R5F51307ADFM#30 implements a CISC Harvard-architecture RX CPU core with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32 multiplication. It integrates an Event Link Controller (ELC) enabling direct hardware-triggered module operation during CPU sleep, and a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes activated by 47 event sources.
Its clock system includes high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL (4–8 MHz input), and IWDT-dedicated 15 kHz oscillator, with independent clock domains for ICLK (CPU/system), PCLKB (peripherals), and FCLK (FlashIF). The MCU supports three low-power modes - sleep, deep sleep, and software standby - with 4.8 µs wake-up time from standby.

FAQ
What is the maximum operating frequency and core performance of the R5F51307ADFM#30?
The R5F51307ADFM#30 operates at a maximum frequency of 32 MHz, delivering 50 DMIPS performance. Its 32-bit RX CPU core features a 5-stage pipeline, variable-length instruction set, and 64-bit accumulator capable of single-cycle 32×32 multiplication. Performance is sustained across the full 1.8–5.5 V supply range, with clock accuracy maintained by the on-chip 32 MHz ±1% oscillator or external crystal.
Does the R5F51307ADFM#30 support real-time clock (RTC) functionality?
Yes, the R5F51307ADFM#30 includes a dedicated RTC module powered by the 32.768 kHz sub-clock oscillator. It supports both calendar count mode (with leap-year and 30-second adjustment) and binary count mode, and generates alarm, periodic, and carry interrupts. The RTC remains operational during software standby mode, enabling time-stamped logging and scheduled wake-up without CPU intervention.
How many capacitive touch keys does the R5F51307ADFM#30 support in its 64-pin package?
In the PLQP0064KB-C 64-pin package, the R5F51307ADFM#30 supports up to 32 capacitive touch keys using mutual capacitance mode. This is confirmed in Table 1.2 of the datasheet, which specifies "32 channels" for CTSU in 64-pin variants. The device also supports self-capacitance mode (1 key per pin) but mutual mode is used for higher channel density and noise immunity in HMI applications.
What low-power modes are available on the R5F51307ADFM#30, and what is the lowest supply current?
The R5F51307ADFM#30 offers three low-power modes: sleep, deep sleep, and software standby. In software standby mode, supply current drops to 0.37 µA (typical) while retaining SRAM content and enabling wake-up via LPT, RTC, or external interrupt. Recovery time from this state is 4.8 µs, and the LPT continues running using the sub-clock or IWDT-dedicated oscillator to maintain timing integrity.
Is the R5F51307ADFM#30 qualified for IEC60730 Class B compliance?
Yes, the R5F51307ADFM#30 includes hardware-assisted IEC60730 Class B compliance features: self-diagnostic A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated oscillator, RAM test support via Data Operation Circuit (DOC), and analog input disconnection detection. These are documented in the "Useful functions for IEC60730 compliance" section of the datasheet and require no external components to implement.
