Product details
Overview
R7F100GGN3CFB#AA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit MCU with 512 KB code flash, 8 KB data flash, and 48 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 (up to 64 keys), and dual-clock domain operation for industrial control and sensor node applications.
For engineers reviewing the R7F100GGN3CFB#AA0 datasheet, R7F100GGN3CFB#AA0 pinout, R7F100GGN3CFB#AA0 application, or R7F100GGN3CFB#AA0 equivalent, key selection considerations include its 48-pin LFQFP-0.5 mm pitch package, -40°C to +105°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-accelerated CTSU2L capacitive touch unit supporting self- and mutual-capacitance configurations.
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 dedicated SNOOZE mode sequencer (SMS) that executes up to 32 preconfigured commands-including ADC sampling, comparator comparison, and timer counting-without CPU, RAM, or flash activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between peripherals, a Data Transfer Controller (DTC) supporting chain transfers across UART, SPI, and I²C channels, and a Realtime Clock with alarm, calendar, and clock correction functions-all operating in STOP mode with 32.768 kHz crystal or internal oscillator.
