Renesas R5F100FGGFP#V0

Overview

R5F100FGGFP#V0 from Renesas is a 44-pin LQFP-44, 96 KB flash, 8 KB data flash, 8 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered HMI control panels.

For engineers reviewing the R5F100FGGFP#V0 datasheet, R5F100FGGFP#V0 pinout, R5F100FGGFP#V0 application, or R5F100FGGFP#V0 equivalent, key selection criteria include its integrated RTC with calendar/alarm, 10-bit 24-channel ADC with internal temperature sensor, dual UART/LIN support, and hardware multiplier/accumulator for real-time motor control math.

Technical Context

The R5F100FGGFP#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.

Its peripheral set includes up to 16× 16-bit timers, 1× 12-bit interval timer, 1× real-time clock with calendar and clock correction, 1× watchdog timer, and serial interfaces: 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels - all configurable via dedicated SFRs and interrupt vectors.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F100FGGFP#V0?

The R5F100FGGFP#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the high-speed on-chip oscillator, which maintains ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C. The RL78 core's 3-stage pipeline and efficient CISC instruction set enable this throughput while sustaining ultra-low power consumption - a key differentiator versus competing 16-bit MCUs.

Does the R5F100FGGFP#V0 support LIN bus communication, and how is it implemented?

Yes, the R5F100FGGFP#V0 supports LIN 2.2 communication via UART0, which includes dedicated hardware for LIN break detection, sync field generation, and checksum calculation. No external transceiver is needed for basic slave-node operation. The UART's built-in timing control meets LIN physical layer tolerances, and the MCU's STOP mode with wake-on-LIN enables sub-μA standby current - making R5F100FGGFP#V0 suitable for automotive door modules and seat controllers.

What are the data flash endurance and voltage requirements for rewriting the R5F100FGGFP#V0?

The R5F100FGGFP#V0 features 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full supply range of 1.8 V to 5.5 V. Rewrites can occur in background operation (BGO), allowing program execution from code flash during data flash updates. The flash library reserves specific RAM regions (e.g., FAF00H for R5F100xJ variants) for safe self-programming - details are documented in R20UT2944.

How does the R5F100FGGFP#V0 achieve 0.57 μA RTC+LVD operation, and what peripherals remain active?

The R5F100FGGFP#V0 achieves 0.57 μA in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) enabled - both powered by the dedicated 32.768 kHz subsystem clock. During this state, the main CPU, flash, RAM, and all digital peripherals are halted. The RTC maintains calendar, alarm, and clock correction functions; the LVD monitors VDD at one of 14 selectable thresholds and can trigger interrupt or reset. This configuration is validated per datasheet R01DS0131EJ0380 Rev.3.80.

Is the R5F100FGGFP#V0 pin-compatible with other RL78/G13 variants in the same LQFP-44 package?

Yes, all RL78/G13 devices in the 44-pin LQFP package (e.g., R5F100FGGFP#V0, R5F100EGGFP#V0, R5F101FGGFP#V0) share identical pinouts and electrical characteristics per the common outline drawing PLQP0044GC-A. Differences are limited to memory sizes, data flash presence, and factory-programmed options - enabling drop-in replacement for functional upgrades or cost optimization without PCB revision.
