Overview
R7F100GPJ2DFB#BA0 from Renesas is a 100-pin, 5.0-mm × 5.0-mm LFQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6 V to 5.5 V across -40°C to +85°C. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and multiple serial interfaces for low-power industrial control and sensor node applications.
For engineers reviewing the R7F100GPJ2DFB#BA0 datasheet, R7F100GPJ2DFB#BA0 pinout, R7F100GPJ2DFB#BA0 application, or R7F100GPJ2DFB#BA0 equivalent, key selection criteria include its 256 KB flash / 24 KB RAM configuration, 100-pin LFQFP-0.5 mm pitch package, integrated CTSU2L for up to 64-key mutual-capacitance touch, and support for SNOOZE mode sequencer for ultra-low-power periodic sensing without CPU wake-up.
Technical Context
The R7F100GPJ2DFB#BA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its power management includes HALT, STOP, and SNOOZE modes - the latter enabling autonomous 32-step command sequencing using 21 available instructions while keeping CPU, flash, and RAM powered down.
Peripheral integration includes Logic & Event Link Controller (ELCL) for configurable signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer, and Serial Interface IICA (up to 10 channels), UARTA (up to 6 channels), and CSI (up to 8 channels), all configurable via peripheral I/O redirection register (PIOR).
