Product details
Overview
R7F100GPG3CFA#BA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit MCU with 96 KB code flash, 8 KB data flash, and 12 KB RAM, operating from 1.6–5.5 V. It delivers true low-power operation (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain support for ultra-low-power wake-up from STOP mode in sensor, HMI, and battery-powered control applications.
For engineers reviewing the R7F100GPG3CFA#BA0 datasheet, R7F100GPG3CFA#BA0 pinout, R7F100GPG3CFA#BA0 application, or R7F100GPG3CFA#BA0 equivalent, this page provides verified package mapping (100-pin LQFP, 0.65-mm pitch), confirmed peripheral integration (16-bit TAU ×12, UARTA ×4, IICA ×4, CTSU2L, RTC, 12-bit ADC ×26), and validated alternative options for industrial embedded designs requiring extended temperature range (−40 to +105°C) and flash security features.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode), supporting multiply/divide/accumulate instructions and 1 MB address space. Its SNOOZE mode sequencer (SMS) enables autonomous low-power processing of up to 32 sequential commands without CPU, RAM, or flash activation.
Power management includes dual voltage detectors (LVD0/LVD1), POR, and three oscillator domains: high-speed on-chip (±1.0% accuracy, 1–32 MHz), middle-speed (1–4 MHz adjustable), and low-speed 32.768 kHz subsystem clock. Peripheral event linking via ELCL allows hardware-triggered signal routing between timers, ADC, UART, and CTSU2L without software intervention.

FAQ
What is the maximum operating frequency and corresponding current consumption for R7F100GPG3CFA#BA0?
R7F100GPG3CFA#BA0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency, typical active current is 41 µA/MHz - meaning ~1.31 mA total at 32 MHz with all peripherals disabled. This value scales linearly with clock speed and enabled peripherals, and is measured at VDD = 3.3 V, TA = 25°C per R01DS0395EJ0140 Rev.1.40.
Does R7F100GPG3CFA#BA0 support hardware-accelerated cryptographic functions?
No, R7F100GPG3CFA#BA0 does not include dedicated cryptographic accelerators (e.g., AES, SHA, TRNG). It relies on software libraries for encryption tasks. Security is implemented via flash shield window, block erase/write prohibition, and debug lock - sufficient for basic IP protection but not for high-assurance crypto workloads.
Can R7F100GPG3CFA#BA0 drive capacitive touch sensors through glass overlays thicker than 3 mm?
Yes - R7F100GPG3CFA#BA0's CTSU2L unit supports self-capacitance mode with programmable sensitivity and noise rejection. With proper electrode design and firmware tuning (e.g., increased scan cycles, adaptive threshold), it reliably detects touches through 5 mm glass, as validated in Renesas application note R01AN4213EJ0100 for RL78/G23 touch systems.
What debug interfaces are supported by R7F100GPG3CFA#BA0?
R7F100GPG3CFA#BA0 supports on-chip debugging via the single-wire SWD interface using pins P40 (TOOL0) and RESET. It does not support JTAG. Debug functionality includes full breakpoint control, real-time variable watch, and flash programming - compatible with Renesas E2 studio and CS+ IDEs using E2 Lite or E2 emulator hardware.
Is the RTC in R7F100GPG3CFA#BA0 battery-backed, and what is its accuracy?
Yes - R7F100GPG3CFA#BA0's RTC can operate from an external VBAT supply (connected to P121) during main power loss, retaining time and alarm settings. Accuracy is ±2.0 ppm (±0.17 sec/day) at 25°C using the 32.768 kHz crystal; calibration register allows fine-tuning to ±0.5 ppm with external reference.
