Product details
Overview
R7F102GBC3CNP#HA0 from Renesas is a 32-pin HWQFN-packaged RL78/G22 16-bit microcontroller with 32 KB code flash, 4 KB RAM, and integrated capacitive touch sensing for up to 29 keys. It operates from 1.6–5.5 V, delivers 37.5 µA/MHz active current and 200 nA STOP-mode current, and supports UART, I²C, SPI, RTC, and 10-bit ADC - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102GBC3CNP#HA0 datasheet, R7F102GBC3CNP#HA0 pinout, R7F102GBC3CNP#HA0 application, or R7F102GBC3CNP#HA0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.50-mm pitch) package, -40 to +85°C temperature grade, C-grade industrial qualification, and hardware-accelerated CTSU2La capacitive sensing unit enabling low-power touch wake-up without CPU intervention.
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 (SMS) supporting 32 sequential commands across 21 operation types, enabling autonomous low-power sensor polling and threshold evaluation.
Peripheral integration includes an Event Link Controller (ELC) routing 20 event signals between peripherals, a Data Transfer Controller (DTC) with chain transfer capability, and dual I²C interfaces (IICA0/IICA1) with clock stretching support. The 10-bit ADC features internal 1.48 V reference and temperature sensor, while the RTC provides alarm interrupt and ±1 ppm correction capability over 99 years.

The R7F102GBC3CNP#HA0 supports up to 4 UARTA channels (with LIN-bus compliance), 6 IICA channels (I²C), and 5 CSI channels (SPI-compatible). Its Event Link Controller (ELC) enables hardware-level routing between these interfaces and peripherals like ADC or timers - eliminating software latency in time-critical data transfers.
Is there a real-time clock (RTC) integrated into the R7F102GBC3CNP#HA0?
Yes, the R7F102GBC3CNP#HA0 includes a fully featured RTC with calendar function (year/month/day/hour/minute/second), alarm interrupt, and clock correction capability (±1 ppm accuracy).
