Renesas R5F51307ADFK#30

Overview

R5F51307ADFK#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 384 KB on-chip flash, 48 KB SRAM, 8 KB data flash, 12-bit A/D converter (14 channels), two 8-bit D/A outputs, capacitive touch sensing (32 channels), RTC, and IEC60730-compliant safety functions - deployed in industrial HMI and consumer appliance control systems.

For engineers reviewing the R5F51307ADFK#30 datasheet, R5F51307ADFK#30 pinout, R5F51307ADFK#30 application, or R5F51307ADFK#30 equivalent, key selection criteria include its LQFP-64 (PLQP0064GA-A, 14×14 mm, 0.8 mm pitch) package, –40°C to +85°C temperature grade, 1.8–5.5 V single-supply operation, and integrated event link controller (ELC) for low-power peripheral coordination without CPU wake-up.

Technical Context

The R5F51307ADFK#30 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates an on-chip high-speed oscillator (32 MHz ±1%), PLL, sub-clock (32.768 kHz), and clock accuracy measurement circuit (CAC) for real-time calibration.

Its peripheral subsystem includes ELC-driven autonomous operation between MTU2 timers, SCI/RIIC/RSPI interfaces, REMC (not supported in this 64-pin LQFP variant), and a 14-channel 12-bit A/D converter with per-channel sampling time control and self-diagnostic capability - all coordinated via the 47-event-capable Event Link Controller.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51307ADFK#30?

The R5F51307ADFK#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its RXv1 32-bit CPU core supports single-cycle 32×32-bit multiplication with a 64-bit accumulator, variable-length instructions for code density, and a 5-stage pipeline for efficient instruction throughput - confirmed in the R01DS0273EJ0300 Rev.3.00 datasheet Section 1.1.

Which package type and pin count does the R5F51307ADFK#30 use?

The R5F51307ADFK#30 uses the PLQP0064GA-A package: a 64-pin LQFP with 14 mm × 14 mm body size and 0.8 mm lead pitch. This differs from the 0.5 mm pitch LFQFP variants (e.g., PLQP0064KB-C) and is explicitly designated by the "FK" suffix in the part number per Figure 1.1 of the datasheet.

How many analog-to-digital converter channels does the R5F51307ADFK#30 support?

The R5F51307ADFK#30 supports 14 channels of 12-bit A/D conversion, as specified in Table 1.2 (Comparison of Functions) for the 64-pin LQFP package. These are mapped to pins AN000–AN007 and AN016–AN029, with per-channel sampling time programmability and self-diagnostic capability - distinct from higher-pin-count variants offering up to 24 channels.

Does the R5F51307ADFK#30 include a real-time clock (RTC) and capacitive touch sensing?

Yes, the R5F51307ADFK#30 includes a full-featured RTC with calendar/binary modes, leap-year adjustment, and alarm/periodic interrupts, plus a Capacitive Touch Sensing Unit (CTSU) supporting up to 32 keys. Both are active in the 64-pin LQFP package per Table 1.2 and Section 1.4 (Pin Functions) of the datasheet.

What safety certifications or diagnostic features does the R5F51307ADFK#30 support?

The R5F51307ADFK#30 includes hardware-assisted features for IEC60730 Class B compliance: A/D converter disconnection detection, clock accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, RAM test assistance via the Data Operation Circuit (DOC), and self-diagnostic routines - all documented in Section 1. Overview and Section 24 of the R01DS0273EJ0300 datasheet.
