Product details
Overview
R7F100GPG3CFA#AA0 from Renesas is a 100-pin, industrial-grade RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and hardware SNOOZE mode sequencer for autonomous low-power operation in battery-powered HMI and sensor edge nodes.
For engineers reviewing the R7F100GPG3CFA#AA0 datasheet, R7F100GPG3CFA#AA0 pinout, R7F100GPG3CFA#AA0 application, or R7F100GPG3CFA#AA0 equivalent, key selection criteria include its 100-pin LQFP-0.65mm package, -40°C to +105°C industrial temperature rating, CTSU2L support for up to 64-key mutual-capacitance touch, and SNOOZE mode sequencer enabling CPU-free periodic sensing without wake-up latency.
Technical Context
The R7F100GPG3CFA#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 predefined commands-including ADC sampling, comparator evaluation, and timer comparisons-without CPU, RAM, or flash activation, reducing system-level power by eliminating wake-up overhead.
Peripherals are tightly coupled via the Event Link Controller (ELCL), enabling direct hardware-triggered signal routing between modules (e.g., ADC end-of-conversion → DMA transfer → UART transmit), while the Data Transfer Controller (DTC) supports block, repeat, and chain transfers activated by 128+ interrupt sources-critical for deterministic real-time data handling in industrial control loops.
