Product details
Overview
R7F102GGC2DFB#AA0 from Renesas is a 48-pin LFQFP, 5.5-V tolerant 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 at -40°C to +85°C. It integrates capacitive touch sensing (up to 29 keys), 10-bit ADC (10 channels), RTC, UART/I²C/SPI interfaces, and ultra-low-power STOP mode (200 nA).
For engineers reviewing the R7F102GGC2DFB#AA0 datasheet, R7F102GGC2DFB#AA0 pinout, R7F102GGC2DFB#AA0 application, or R7F102GGC2DFB#AA0 equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for industrial control, home appliance HMI, and battery-powered sensor nodes.
Technical Context
The RL78/G22 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing-0.03125 µs at 32 MHz (high-speed on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). It supports multiply/divide/accumulate instructions and 1 MB address space.
Power management includes HALT, STOP, and SNOOZE modes; STOP mode enables high-speed wakeup and consumes only 200 nA. The SNOOZE mode sequencer executes up to 32 low-power processes without CPU, flash, or RAM activation using 21 command types.
