Product details
Overview
R7F100GGJ3CNP#AA0 from Renesas is a 48-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V across –40 to +105°C industrial temperature range. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and ultra-low-power STOP mode (210 nA data retention).
For engineers reviewing the R7F100GGJ3CNP#AA0 datasheet, R7F100GGJ3CNP#AA0 pinout, R7F100GGJ3CNP#AA0 application, or R7F100GGJ3CNP#AA0 equivalent, key selection criteria include its 256 KB flash capacity in HWQFN-48 package, industrial-grade thermal rating, integrated CTSU2L for touch HMI, and support for SNOOZE mode sequencer for autonomous low-power sensor polling.
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) and supports multiply/divide/MAC instructions. It features dual clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and independent subsystem clock (32.768 kHz).
Peripheral integration includes a 32-process SNOOZE mode sequencer (SMS) that executes comparator-triggered conditional logic without CPU wake-up, an Event Link Controller (ELCL) enabling hardware-level signal routing between peripherals, and background operation (BGO) for concurrent data flash rewriting and program execution.

External crystal (XT1/XT2) and resonator support is provided via P121/P122 pins.
Does the R7F100GGJ3CNP#AA0 support in-system programming and secure firmware updates?
Yes, the R7F100GGJ3CNP#AA0 supports full in-system programming via on-chip debugging interface and includes flash security features: block erase/write prohibition, flash shield window for protected code regions, and boot swapping for atomic firmware updates. These capabilities ensure safe, field-upgradable firmware deployment without exposing sensitive IP.
How many analog-to-digital converter (ADC) channels does the R7F100GGJ3CNP#AA0 provide, and what resolutions are supported?
The R7F100GGJ3CNP#AA0 integrates a 12-bit successive-approximation ADC with up to 26 input channels. It supports selectable resolution modes (8-bit, 10-bit, or 12-bit), internal 1.48 V reference voltage, and on-chip temperature sensor - enabling precise analog measurements for sensor conditioning, battery monitoring, and thermal management without external reference components.
