Product details
Overview
R7F102GBE3CFP#AA0 from Renesas is a 32-pin LQFP-packaged RL78/G22 16-bit microcontroller featuring 64 KB code flash, 4 KB RAM, and ultra-low-power operation (37.5 µA/MHz active, 200 nA STOP mode). It integrates capacitive touch sensing (up to 29 keys), 10-bit ADC (10 channels), RTC, and multiple serial interfaces including UART, I²C, and SPI - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102GBE3CFP#AA0 datasheet, R7F102GBE3CFP#AA0 pinout, R7F102GBE3CFP#AA0 application, or R7F102GBE3CFP#AA0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade, 1.6–5.5 V supply range, integrated CTSU2La capacitive sensing unit, and support for SNOOZE mode sequencer-driven low-power wake-up without CPU involvement.
Technical Context
The RL78/G22 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports multiply/divide/accumulate instructions and features a 1 MB address space with four banks of 8×8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes; the latter enables autonomous execution of up to 32 sequential operations using 21 built-in commands - offloading the CPU while maintaining sub-µA system-level power consumption during intermittent sensing tasks.
