Product details
Overview
R7F102GBC2DFP#AA0 from Renesas is a 32-pin LQFP-32, 32-KB flash, 4-KB RAM RL78/G22 16-bit microcontroller operating from 1.6 V to 5.5 V, featuring 37.5 µA/MHz active current, 200 nA STOP mode, and up to 29 capacitive touch sensing channels - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102GBC2DFP#AA0 datasheet, R7F102GBC2DFP#AA0 pinout, R7F102GBC2DFP#AA0 application, or R7F102GBC2DFP#AA0 equivalent, this page delivers verified package mapping (LQFP-32, 7×7 mm, 0.80-mm pitch), confirmed 32-KB/4-KB memory split, validated CTSU2La touch channel count, RTC alarm capability, and UARTA/IICA/SPI interface availability per Renesas R01DS0424EJ0120 Rev.1.20.
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 on-chip oscillator) or 30.5 µs at 32.768 kHz (subsystem clock). It integrates a SNOOZE mode sequencer supporting 32 sequential low-power operations without CPU, RAM, or flash activation.
Peripheral integration includes an 8-/10-bit ADC with internal 1.48-V reference and temperature sensor, 16-bit TAU with 8 channels, RTC with 1-s to 99-year counting and alarm interrupt, and event link controller (ELC) enabling 20 configurable peripheral-to-peripheral signal paths without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102GBE2DFP#AA0 | 64 KB code flash, same 32-pin LQFP package, identical peripherals and pinout - differs only in flash capacity. | Required when firmware exceeds 32 KB or future-proofing for feature expansion is needed. | Select R7F102GBE2DFP#AA0 if bootloader, OTA stack, or cryptographic libraries demand >32 KB executable space. |
| R7F102GBC2CFP#AA0 | Same 32 KB flash, 4 KB RAM, and peripherals but in 32-pin HWQFN (5×5 mm, 0.50-mm pitch) with exposed die pad - not pin-compatible. | Preferred for space-constrained PCBs where thermal performance and smaller footprint outweigh re-layout effort. | Choose R7F102GBC2CFP#AA0 only when board area is critical and thermal dissipation via exposed pad is required. |
