Product details
Overview
R7F102GCC2DLA#BC0 from Renesas is a 36-pin WFLGA-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 V to 5.5 V. It integrates capacitive touch sensing (up to 29 keys), 10-bit ADC (18 channels), RTC, UART/I²C/SPI interfaces, and ultra-low-power modes including 200-nA STOP and 37.5-µA/MHz active current - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102GCC2DLA#BC0 datasheet, R7F102GCC2DLA#BC0 pinout, R7F102GCC2DLA#BC0 application, or R7F102GCC2DLA#BC0 equivalent, key selection criteria include its 36-pin WFLGA (4 × 4 mm, 0.50-mm pitch) footprint, -40 to +85°C temperature grade, CTSU2La capacitive touch unit, and support for SNOOZE mode sequencer-driven autonomous low-power sensing.
Technical Context
The RL78/G22 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode), supporting multiply/divide/accumulate instructions and 1 MB address space. It includes dedicated hardware accelerators: SNOOZE mode sequencer (SMS) for CPU-free periodic sensor polling, and event link controller (ELC) enabling direct peripheral-to-peripheral triggering without CPU intervention.
Power management integrates POR, dual LVDs (LVD0/LVD1), HALT/STOP/SNOOZE modes, and a high-accuracy ±1.0% on-chip oscillator (32 MHz max). The CTSU2La unit supports both self-capacitance (single-key per pin) and mutual-capacitance (matrix) touch sensing across up to 29 pins, with built-in noise immunity and automatic drift compensation.
