Renesas R5F100PGGFA#10

Overview

R5F100PGGFA#10 from Renesas is a 100-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed (41 DMIPS), and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC with calendar, and operates from 1.6–5.5 V across –40°C to +105°C for industrial control and sensor node applications.

For engineers reviewing the R5F100PGGFA#10 datasheet, R5F100PGGFA#10 pinout, R5F100PGGFA#10 application, or R5F100PGGFA#10 equivalent, key selection criteria include its industrial-grade temperature range (–40°C to +105°C), integrated LIN-capable UARTs for automotive body electronics, background data flash rewrite capability, and hardware multiplier/divider for real-time signal processing in resource-constrained embedded systems.

Technical Context

The R5F100PGGFA#10 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO) and 1M-cycle endurance, and 12 KB on-chip RAM.

Peripherals are tightly coupled to low-power operation: dual 16-bit timer arrays (up to 16 channels), 10-bit ADC with internal 1.45 V reference and temperature sensor, three I²C/Simplified I²C interfaces, two UART/LIN modules, and four CSI channels. Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset selection.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating of the R5F100PGGFA#10?

The R5F100PGGFA#10 operates at up to 32 MHz with the RL78 CPU core delivering 41 DMIPS (Dhrystone MIPS). This performance level is achieved using the high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C, and remains stable under the full industrial temperature range (–40°C to +105°C) per device characterization.

Does the R5F100PGGFA#10 support background data flash rewriting while executing application code?

Yes, the R5F100PGGFA#10 supports background operation (BGO) for data flash. Instructions can be fetched and executed from program memory while simultaneously rewriting the 8 KB data flash - enabling uninterrupted real-time operation during firmware updates, configuration saves, or data logging without halting the main application thread.

What are the key low-power modes supported by the R5F100PGGFA#10, and what is the lowest achievable current draw?

The R5F100PGGFA#10 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables decade-scale battery life in always-on sensor and monitoring applications.

How many analog input channels and what ADC resolution does the R5F100PGGFA#10 provide?

The R5F100PGGFA#10 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated on-chip temperature sensor - both accessible via dedicated pins (P20/P21 and ANIxx) - eliminating need for external references or thermal ICs in most designs.

Is the R5F100PGGFA#10 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 100-pin LQFP-0.65mm package (e.g., R5F100PFAFA#10, R5F100PLAFA#10, R5F101PGGFA#10) share identical pinouts and electrical characteristics. This enables hardware reuse across memory variants and feature sets - allowing design scalability from 16 KB to 512 KB flash without PCB revision.
