Product details
Overview
R7F100GGJ2DNP#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 at -40 to +85°C, featuring capacitive touch sensing, 16-bit timers, UART/I²C/SPI interfaces, and ultra-low-power STOP mode (210 nA data retention). It targets battery-powered consumer HMI and sensor-edge applications.
For engineers reviewing the R7F100GGJ2DNP#AA0 datasheet, R7F100GGJ2DNP#AA0 pinout, R7F100GGJ2DNP#AA0 application, or R7F100GGJ2DNP#AA0 equivalent, key selection criteria include its 256 KB flash/24 KB RAM configuration, HWQFN-48 package with 0.5-mm pitch, integrated CTSU2L capacitive sensing unit supporting up to 64 keys, and dual-voltage I/O capability for interfacing with 1.8/2.5/3.0-V peripherals.
Technical Context
The R7F100GGJ2DNP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer enables autonomous low-power peripheral sequencing without CPU wake-up.
It integrates a Logic and Event Link Controller (ELCL) for configurable event routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers, and a Realtime Clock with alarm and clock correction-enabling deterministic timing control in energy-constrained systems.
