Overview
R7F100GBJ2DFP#AA0 from Renesas is an RL78/G23 32-bit ultra-low-power MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V. It features a 32-MHz high-accuracy on-chip oscillator (±1.0%), 16-bit timer array (12 channels), 12-bit A/D converter (26-channel), capacitive touch sensing unit (CTSU2L), and integrated UART/I²C/SPI interfaces - deployed in battery-powered industrial sensors and smart home control nodes.
For engineers reviewing the R7F100GBJ2DFP#AA0 datasheet, R7F100GBJ2DFP#AA0 pinout, R7F100GBJ2DFP#AA0 application, or R7F100GBJ2DFP#AA0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.5-mm pitch) package, -40 to +85°C consumer-grade temperature range, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-based event link controller (ELCL) for peripheral-triggered operations without CPU wake-up.
Technical Context
The R7F100GBJ2DFP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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 - with 210-nA data retention current for 4 KB of RAM and 41-µA/MHz active current.
Peripheral integration includes a 32-bit interval timer, real-time clock (RTC) with alarm and correction, 2-channel 8-bit D/A converter, 2-channel comparator with selectable internal/external reference, and remote control signal receiver supporting four waveform pattern matches - all configurable via dedicated registers and supported by the Data Transfer Controller (DTC) for zero-CPU background transfers.
