Product details
Overview
R7F100GBJ3CNP#AA0 from Renesas is a 32-pin, industrial-grade 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 (CTSU2L), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-speed (32.768 kHz) modes for battery-powered sensor nodes and smart industrial controls.
For engineers reviewing the R7F100GBJ3CNP#AA0 datasheet, R7F100GBJ3CNP#AA0 pinout, R7F100GBJ3CNP#AA0 application, or R7F100GBJ3CNP#AA0 equivalent, this page provides verified technical context, validated pin functions for HWQFN-32 package, real-world use cases in low-power HMI and industrial monitoring, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The R7F100GBJ3CNP#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz / 30.5 µs @ 32.768 kHz). It integrates a SNOOZE mode sequencer (SMS) enabling autonomous low-power peripheral sequencing without CPU wake-up, and an Event Link Controller (ELCL) for hardware-triggered signal routing between peripherals like timers, ADC, and UART.
Its analog subsystem includes a 12-bit A/D converter (26 channels), 2-channel 8-bit D/A, 2 comparators with selectable internal/external reference, and a dedicated capacitive sensing unit supporting up to 64 keys via mutual capacitance matrix. Power management features HALT, STOP, and SNOOZE modes with fast wakeup from STOP, plus POR and dual voltage detectors (LVD0/LVD1).
