Product details
Overview
R7F100GFG3CFP#AA0 from Renesas is a 44-pin LQFP-packaged RL78/G23 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 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), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces including UART, I²C, and SPI for industrial control and sensor node applications.
For engineers reviewing the R7F100GFG3CFP#AA0 datasheet, R7F100GFG3CFP#AA0 pinout, R7F100GFG3CFP#AA0 application, or R7F100GFG3CFP#AA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +105°C industrial temperature grade, SNOOZE mode sequencer for autonomous low-power operation, and CTSU2L capacitive sensing unit supporting mutual/self-capacitance configurations.
Technical Context
The R7F100GFG3CFP#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) that executes up to 32 preconfigured commands-including comparisons and calculations-without CPU, RAM, or flash activation, enabling deterministic low-power wake-up sequences.
Peripheral integration includes a Logic and Event Link Controller (ELCL) for configurable event routing between peripherals, Data Transfer Controller (DTC) with chain transfer support, and a Remote Control Signal Receiver (REMC) with 4-waveform pattern matching for IR remote decoding-all operating within the same 1.6–5.5 V supply range and industrial temperature envelope.
