Renesas R5F51104AGFM#30

Overview

R5F51104AGFM#30 from Renesas is a 32-bit RX CPU-based microcontroller operating at up to 32 MHz (50 DMIPS), featuring 96 KB on-chip flash, 16 KB SRAM, 12-bit A/D converter with 14 channels, RTC, and dual SCI + I²C + RSPI interfaces. It targets low-power industrial sensing and control applications requiring deterministic real-time response and IEC 60730 compliance.

For engineers reviewing the R5F51104AGFM#30 datasheet, R5F51104AGFM#30 pinout, R5F51104AGFM#30 application, or R5F51104AGFM#30 equivalent, this page delivers verified specifications, package mapping to PLQP0064KB-A (64-pin LFQFP, 10 × 10 mm, 0.5 mm pitch), validated pin functions, and two confirmed alternative parts for design continuity.

Technical Context

The R5F51104AGFM#30 implements a CISC Harvard architecture with five-stage pipeline and variable-length instructions, enabling ultra-compact code and single-cycle instruction execution. Its on-chip clock system integrates high-speed (32 MHz ±1%), sub-clock (32.768 kHz), and IWDT-dedicated (15 kHz) oscillators with CAC for frequency accuracy monitoring.

It supports three low-power modes-sleep, deep sleep, and software standby-with 0.35 μA standby current and 4.8 μs wake-up time. Peripheral integration includes MTU2 (4-channel 16-bit timer), CMT (2-channel), DTC for interrupt-triggered transfers, and hardware CRC calculation using X⁸+X²+X+1, X¹⁶+X¹⁵+X²+1, or X¹⁶+X¹²+X⁵+1 polynomials.

FAQ

What is the maximum operating frequency and associated performance of the R5F51104AGFM#30?

The R5F51104AGFM#30 operates at a maximum frequency of 32 MHz, delivering 50 DMIPS performance. This speed is achievable only when the supply voltage is 2.7–3.6 V; at lower voltages (1.8–2.4 V), the maximum frequency drops to 8 MHz. The RX CPU core's five-stage pipeline and single-cycle instruction execution enable deterministic real-time behavior critical for industrial control loops.

Does the R5F51104AGFM#30 support IEC 60730 Class B functional safety compliance?

Yes, the R5F51104AGFM#30 includes hardware features required for IEC 60730 Class B: clock frequency accuracy measurement circuit (CAC), independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, voltage detection circuits (LVDA), and RAM test assist functions. These are documented in the datasheet and enable certified self-test routines without external components.

What package type and dimensions does the R5F51104AGFM#30 use?

The R5F51104AGFM#30 uses the PLQP0064KB-A package: a 64-pin Low-Profile Quad Flat Package measuring 10 × 10 mm with 0.5 mm pitch. This LFQFP variant has no exposed thermal pad. Pin assignments match other 64-pin RX110 variants, enabling layout reuse across memory-graded parts like R5F51103AGFM#30 and R5F51105AGFM#30.

How many A/D converter channels does the R5F51104AGFM#30 support, and what is its minimum conversion time?

The R5F51104AGFM#30 integrates a 12-bit A/D converter with 14 input channels (AN000–AN015, excluding AN005/AN007). At maximum clock speed (ADCLK = 32 MHz), its minimum conversion time is 1.0 μs per channel. It also supports double-trigger mode for simultaneous sampling-essential for motor current sensing and differential measurements.

What communication interfaces are integrated into the R5F51104AGFM#30?

The R5F51104AGFM#30 integrates five serial interfaces: two SCI channels (SCI1 and SCI5) supporting asynchronous, clock-synchronous, simple I²C, and simple SPI modes; one SCIf channel (SCI12) with extended serial capability; one I²C bus interface (RIIC) compliant with SMBus and fast-mode (400 kbps); and one RSPI channel supporting master/slave operation at up to 16 Mbps with four slave-select outputs.
