Product details
Overview
R7F102G7C2DNP#HA0 from Renesas is a 24-pin HWQFN-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6–5.5 V. It delivers true low-power performance (37.5 µA/MHz active, 200 nA STOP mode) and integrates capacitive touch sensing (up to 29 keys), RTC, UART/SPI/I²C interfaces, and 16-bit timers - deployed in battery-powered consumer HMI and sensor nodes.
For engineers reviewing the R7F102G7C2DNP#HA0 datasheet, R7F102G7C2DNP#HA0 pinout, R7F102G7C2DNP#HA0 application, or R7F102G7C2DNP#HA0 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.50-mm pitch) footprint, 32 KB flash/4 KB RAM configuration, -40 to +85°C consumer-grade temperature range, and integrated CTSU2La capacitive sensing unit supporting self- and mutual-capacitance topologies.
Technical Context
The RL78/G22 core employs 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). It supports multiply/divide/MAC instructions and features a 1 MB address space with four banks of 8-bit general-purpose registers.
Power management includes HALT, STOP, and SNOOZE modes - the latter enabled by a dedicated sequencer executing up to 32 processes using 21 command types without CPU, flash, or RAM activation. Peripheral integration includes Event Link Controller (ELC) for 20-event signal routing, Data Transfer Controller (DTC), and dual I²C/SPI/UART channels with LIN support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102G7E2DNP#HA0 | Same package and pinout; 64 KB code flash (vs. 32 KB), identical peripherals and low-power specs | Required when firmware exceeds 32 KB or future-proofing for feature expansion is needed | Select if larger code memory is required without changing PCB layout or firmware architecture |
| STM32L071KBT6 | ARM Cortex-M0+, 128 KB flash, 20 KB RAM; higher active current (116 µA/MHz), no integrated CTSU | Used where ARM ecosystem tooling or higher compute throughput is prioritized over capacitive touch integration | Choose when migrating to ARM-based development flow or needing >32 KB flash with richer peripheral set (e.g., USB, AES) |
