Renesas R5F52107CDFM#30

Overview

R5F52107CDFM#30 from Renesas Electronics is a 32-bit RX CPU-based microcontroller operating at up to 50 MHz (78 DMIPS), featuring 384 KB on-chip flash, 64 KB SRAM, 8 KB data flash, 12-bit A/D converter (16 channels, 1 μs conversion), and real-time clock with deep software standby wake-up capability - deployed in industrial control panels requiring deterministic timing and IEC60730-compliant self-diagnostic functions.

For engineers reviewing the R5F52107CDFM#30 datasheet, R5F52107CDFM#30 pinout, R5F52107CDFM#30 application, or R5F52107CDFM#30 equivalent, key selection considerations include its 64-pin LQFP (PLQP0064KB-A) package, 5-V-tolerant I/O, ELC event-driven peripheral activation, MPC pin function remapping, and integrated temperature sensor for closed-loop thermal management.

Technical Context

The R5F52107CDFM#30 implements a CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and 64-bit accumulator for single-cycle 32×32-bit multiply-accumulate operations. Its clock system integrates PLL, sub-clock (32.768 kHz), high/low-speed on-chip oscillators, and IWDT-dedicated 125-kHz oscillator with accuracy measurement (CAC).

Peripheral coordination is managed via Event Link Controller (ELC), enabling direct module triggering without CPU intervention, and Multi-function Pin Controller (MPC) for flexible I/O assignment. The MCU supports four low-power modes including deep software standby with RTC active, and operates across 1.62–5.5 V supply with voltage detection circuits (LVDAa) configurable across 4–16 levels.

FAQ

What is the maximum operating frequency and CPU performance of the R5F52107CDFM#30?

The R5F52107CDFM#30 operates at a maximum frequency of 50 MHz and delivers 78 DMIPS of processing performance. Its 32-bit RX CPU core features a 5-stage pipeline, variable-length instructions, and a 64-bit accumulator capable of single-cycle 32×32-bit multiplication with accumulation. Performance is sustained across the full 1.62–5.5 V supply range, with frequency scaling tied to voltage (e.g., 20 MHz at 1.62–1.8 V).

Does the R5F52107CDFM#30 support IEC60730 compliance for household appliance control?

Yes, the R5F52107CDFM#30 includes dedicated hardware features for IEC60730 Class B compliance, including self-diagnostic functions for the A/D converter, clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT), RAM test assistance, and analog input disconnection detection. These are documented in Renesas Application Note R01AN1305EU0100 and verified in the R01DS0041EJ0150 datasheet.

What package type and pin count does the R5F52107CDFM#30 use?

The R5F52107CDFM#30 uses a 64-pin LQFP package designated PLQP0064KB-A: 10 × 10 mm body size, 0.5-mm pitch, with exposed thermal pad. This package supports 48 general-purpose I/O pins, 2 of which are 5-V tolerant, and is RoHS-compliant with matte tin terminal finish. Pinout matches the RX210 Group 64-pin LQFP standard per datasheet pages 192–199.

How many A/D converter channels and what resolution does the R5F52107CDFM#30 provide?

The R5F52107CDFM#30 integrates a 12-bit successive-approximation A/D converter (S12AD) with 16 input channels (AN000–AN015). It achieves a minimum conversion time of 1.0 μs per channel when ADCLK runs at 50 MHz. The module supports scan modes (single, continuous, group), sample-and-hold for three channels, and synchronized sampling across three channels - all confirmed in Section 24.3 of R01DS0041EJ0150.

What low-power modes are available on the R5F52107CDFM#30, and which retain RTC functionality?

The R5F52107CDFM#30 offers four low-power modes: Sleep, All-module Clock Stop, Software Standby, and Deep Software Standby. Only Deep Software Standby retains RTC operation while halting the CPU and nearly all peripherals - enabling wake-up via RTC alarm, periodic interrupt, carry interrupt, or external event signal. This mode draws minimal current while preserving calendar/timekeeping accuracy using the 32.768 kHz sub-clock.
