Product details
Overview
R7F102G6C2DSP#HA0 from Renesas is a 20-pin LSSOP-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash. It delivers true low-power operation (37.5 µA/MHz active, 200 nA STOP mode), integrates capacitive touch sensing for up to 29 keys, and operates across 1.6–5.5 V supply and –40°C to +85°C ambient temperature - deployed in battery-powered consumer HMI systems.
For engineers reviewing the R7F102G6C2DSP#HA0 datasheet, R7F102G6C2DSP#HA0 pinout, R7F102G6C2DSP#HA0 application, or R7F102G6C2DSP#HA0 equivalent, key selection considerations include its 20-pin LSSOP-20 package, 32 KB flash capacity, integrated CTSU2La capacitive touch unit, RTC with alarm, and UART/SPI/I²C interface flexibility for space-constrained embedded control.
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; 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/accumulate instructions. Its memory subsystem includes 32 KB on-chip code flash (2 KB block size), 2 KB data flash with background operation (BGO), and 4 KB SRAM.
Peripheral integration includes a 10-channel 10-bit ADC with internal 1.48 V reference and temperature sensor, SNOOZE mode sequencer (SMS) enabling CPU-free low-power periodic processing, and Event Link Controller (ELC) supporting 20 event-driven peripheral couplings without CPU intervention.
