Product details
Overview
R7F102GBC3CNP#AA0 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 current, and supports industrial temperature range (−40°C to +105°C). It targets ultra-low-power HMI and sensor-edge applications such as smart thermostats and battery-powered control panels.
For engineers reviewing the R7F102GBC3CNP#AA0 datasheet, R7F102GBC3CNP#AA0 pinout, R7F102GBC3CNP#AA0 application, or R7F102GBC3CNP#AA0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.50-mm pitch) package, 32 KB flash/4 KB RAM configuration, CTSU2La-based touch support, RTC with alarm, and dual UART/I²C/SPI interface count - all validated for industrial-grade operation at 105°C ambient.
Technical Context
The R7F102GBC3CNP#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) enabling low-power background processing of up to 32 commands without CPU, flash, or RAM activation.
Peripheral integration includes an 8-/10-bit ADC (up to 10 channels), 16-bit timer array (8 channels), real-time clock with 1-second-to-99-year counting and alarm, watchdog timer, and event link controller (ELC) supporting 20 configurable peripheral event links - all operating within the same 1.6–5.5 V supply range and −40°C to +105°C temperature grade.

FAQ
What is the maximum operating frequency and associated current consumption of the R7F102GBC3CNP#AA0?
The R7F102GBC3CNP#AA0 operates at up to 32 MHz using the high-speed on-chip oscillator (±1.0% accuracy). At this frequency, it draws 37.5 µA per MHz under typical conditions - resulting in ~1.2 mA total active current. This value is measured at VDD = 3.3 V and TA = 25°C, with all peripherals disabled except core logic and clock system.
Does the R7F102GBC3CNP#AA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F102GBC3CNP#AA0 integrates the CTSU2La capacitive touch sensing unit, which requires only a single external capacitor on the TSCAP pin (P30) for calibration. It supports both self-capacitance (up to 29 keys) and mutual-capacitance matrix configurations, with built-in noise cancellation and automatic drift compensation - no external RC networks or dedicated touch ASICs needed.
What debug interface does the R7F102GBC3CNP#AA0 use, and what pins are required?
The R7F102GBC3CNP#AA0 uses the on-chip debug interface accessible via the TOOL0 (P40), TOOLRxD (P11), and TOOLTxD (P12) pins. These three signals enable full SWD-style debugging, flash programming, and real-time trace - all supported by Renesas E2 studio and CS+ IDE without requiring external debug probes beyond standard J-Link or E2 Lite adapters.
How many serial communication interfaces does the R7F102GBC3CNP#AA0 provide, and what protocols are supported?
The R7F102GBC3CNP#AA0 provides up to four UARTA channels (including LIN-bus support), six I²C/Simplified I²C channels, and five CSI (SPI-compatible) channels - all configurable through multiplexed pins. Specific channel counts depend on pin assignment; the 32-pin HWQFN variant supports at minimum two UARTA, two I²C, and two CSI instances simultaneously without conflict.
Is the R7F102GBC3CNP#AA0 qualified for industrial temperature operation, and what is its thermal specification?
Yes, the R7F102GBC3CNP#AA0 is rated for industrial temperature operation from −40°C to +105°C (denoted by "3C" in the part numbering scheme). This qualification covers full functionality of all peripherals - including flash programming, RTC operation, CTSU2La touch sensing, and ADC conversions - across the entire range, with voltage detectors (LVD0/LVD1) active at all temperatures.
