Product details
Overview
R7F100GGG3CNP#AA0 from Renesas is a 48-pin HWQFN-packaged 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), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces including UARTA, IICA, and CSI for industrial control, sensor nodes, and HMI applications.
For engineers reviewing the R7F100GGG3CNP#AA0 datasheet, R7F100GGG3CNP#AA0 pinout, R7F100GGG3CNP#AA0 application, or R7F100GGG3CNP#AA0 equivalent, key selection criteria include its industrial-grade temperature range (−40 to +105°C), 48-pin HWQFN package (7 × 7 mm, 0.50-mm pitch), SNOOZE mode sequencer for autonomous low-power operation, and CTSU2L support for up to 64-key mutual-capacitance touch panels.
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 on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). It integrates a SNOOZE mode sequencer (SMS) supporting 32 sequential commands across 21 instruction types, enabling CPU-free periodic sensing and processing.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and a Remote Control Signal Receiver (REMC) with 4-waveform pattern matching for IR remote decoding-functions confirmed for the R7F100GGG3CNP#AA0 variant per RL78/G23 family documentation.
