Product details
Overview
R7F102G7C2DNP#UA0 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 to 5.5 V. It delivers ultra-low power consumption (37.5 µA/MHz active, 200 nA STOP mode), integrates 10-channel 10-bit ADC, up to 29 capacitive touch sensors, and supports UART, I²C, and SPI interfaces for battery-powered HMI and sensor control applications.
For engineers reviewing the R7F102G7C2DNP#UA0 datasheet, R7F102G7C2DNP#UA0 pinout, R7F102G7C2DNP#UA0 application, or R7F102G7C2DNP#UA0 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.50-mm pitch) package, -40 to +85°C consumer-grade temperature range, 32 KB flash capacity, integrated CTSU2La capacitive sensing unit, and SNOOZE mode sequencer for autonomous low-power event processing.
Technical Context
The R7F102G7C2DNP#UA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer executes up to 32 processes using 21 command types without CPU, flash, or RAM involvement, enabling deterministic low-power background operation.
Peripheral integration includes an Event Link Controller (ELC) routing 20 event signals between peripherals, a Data Transfer Controller (DTC) with chain transfer support, and dual I²C interfaces (IICA0/IICA1) with clock stretching and arbitration. The CTSU2La unit supports both self- and mutual-capacitance sensing with hardware-based noise cancellation and automatic tuning.

The R7F102G7C2DNP#UA0 operates from a single supply rail of 1.6 V to 5.5 V, enabling direct compatibility with common battery chemistries (e.g., 2× alkaline, Li-ion, or coin cells) and eliminating need for external regulators in many applications. This wide range supports brown-out resilience and simplifies power architecture design across diverse end equipment.
Does the R7F102G7C2DNP#UA0 support capacitive touch sensing?
Yes, the R7F102G7C2DNP#UA0 integrates the CTSU2La capacitive sensing unit supporting up to 29 keys using either self-capacitance (single-pin per key) or mutual-capacitance (matrix configuration) methods. It includes hardware-based noise cancellation, automatic tuning, and operates across the full 1.8–5.5 V supply range-making it ideal for robust touch interfaces in variable environmental conditions.
What debug interface does the R7F102G7C2DNP#UA0 provide?
The R7F102G7C2DNP#UA0 provides on-chip debugging via the TOOL0 (P40) pin, compatible with Renesas E2/E2 Lite emulators. It supports full breakpoint, watchpoint, and memory inspection capabilities without requiring additional debug headers or SWD/JTAG pins-reducing PCB footprint and simplifying development setup for the 24-pin HWQFN package.
How many UART channels does the R7F102G7C2DNP#UA0 support?
The R7F102G7C2DNP#UA0 supports up to four UARTA channels, with at least one channel (UARTA0) featuring LIN-bus physical layer compliance. Channel allocation depends on pin multiplexing-e.g., P10/P11/P12 support UARTA0, while P13/P14 support UARTA2-allowing flexible serial connectivity for sensor networks, display modules, or diagnostic interfaces.
Is the R7F102G7C2DNP#UA0 pin-compatible with other RL78/G22 variants?
Yes, the R7F102G7C2DNP#UA0 shares identical pinout and package (24-pin HWQFN, PWQN0024KG-A) with all other R7F102G7x2DNP#UA0 variants-including R7F102G7E2DNP#UA0-enabling seamless flash-size migration without PCB redesign.
