Overview

R5F51305ADFK#30 from Renesas Electronics is a 32-bit RX130 Group microcontroller with 128 KB flash, 16 KB SRAM, and 8 KB data flash, operating at up to 32 MHz (50 DMIPS), featuring integrated 12-bit A/D converter (14 channels), dual 8-bit D/A outputs, capacitive touch sensing (32 channels), RTC, and IEC60730-compliant safety functions for industrial control panels and appliance HMI systems.

For engineers reviewing the R5F51305ADFK#30 datasheet, R5F51305ADFK#30 pinout, R5F51305ADFK#30 application, or R5F51305ADFK#30 equivalent, this MCU delivers verified low-power operation (0.37 µA in software standby), deterministic real-time response via ELC-linked peripherals, and hardware-accelerated CRC/DOC for firmware integrity - critical for certified embedded control designs.

Technical Context

The R5F51305ADFK#30 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions, enabling single-cycle 32×32-bit multiply and 64-bit accumulator operations. Its clock system integrates high-speed on-chip oscillator (32 MHz ±1%), sub-clock (32.768 kHz), PLL, and CAC for frequency accuracy monitoring.

Peripheral coordination is managed by the Event Link Controller (ELC), allowing timer-triggered A/D conversion or PWM updates without CPU intervention, while the Data Transfer Controller (DTC) supports chain transfers across four modes. The device uses the PLQP0064GA-A package (64-pin LQFP, 14×14 mm, 0.8 mm pitch) and operates from 1.8–5.5 V across –40 to +85°C.

FAQ

What is the maximum operating frequency and CPU performance of the R5F51305ADFK#30?

The R5F51305ADFK#30 operates at a maximum frequency of 32 MHz and delivers 50 DMIPS of processing performance. Its 32-bit RX CPU core supports single-cycle 32×32-bit multiplication and a 64-bit accumulator, enabling efficient real-time control algorithms. Performance is sustained across the full 1.8–5.5 V supply range, with frequency scaling tied to VCC voltage levels per datasheet Table 1.1.

Does the R5F51305ADFK#30 support IEC60730 Class B compliance out of the box?

Yes, the R5F51305ADFK#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 DOC, and analog input disconnection detection. These are documented in the datasheet Section 1.1 and require minimal firmware integration to satisfy certification requirements.

How many capacitive touch channels does the R5F51305ADFK#30 support, and what configuration options exist?

The R5F51305ADFK#30 integrates a Capacitive Touch Sensing Unit (CTSU) supporting up to 32 dedicated touch pins (TS0–TS31) in its PLQP0064GA-A package. It supports both self-capacitance (one pin per key) and mutual capacitance (matrix configuration) modes, enabling flexible HMI layouts. The hardware accelerator handles baseline correction and noise rejection, reducing CPU overhead during touch scanning.

What are the low-power consumption modes available on the R5F51305ADFK#30, and what is the lowest achievable current draw?

The R5F51305ADFK#30 offers three low-power modes: Sleep, Deep Sleep, and Software Standby. In Software Standby mode, it draws just 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, making it ideal for battery-powered applications requiring rapid responsiveness after extended idle periods.

Can the R5F51305ADFK#30 perform simultaneous A/D conversion and D/A output without CPU intervention?

Yes, the R5F51305ADFK#30 supports autonomous analog operation via its Event Link Controller (ELC). For example, an MTU2 timer output can trigger A/D conversion start, and the resulting conversion completion event can directly update a D/A channel value - all without CPU involvement. This enables precise, jitter-free analog waveform generation and closed-loop control in real-time systems.
