Product details
Overview
R7F102GBC2DNP#AA0 from Renesas is a 32-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 V 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, RTC, capacitive touch sensing (up to 29 keys), and supports UART, I²C, and SPI interfaces for battery-powered HMI and sensor node applications.
For engineers reviewing the R7F102GBC2DNP#AA0 datasheet, R7F102GBC2DNP#AA0 pinout, R7F102GBC2DNP#AA0 application, or R7F102GBC2DNP#AA0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.50-mm pitch) package, consumer-grade temperature range (–40°C to +85°C), integrated CTSU2La capacitive touch unit, SNOOZE mode sequencer for autonomous low-power sensing, and hardware-based event link controller (ELC) for deterministic peripheral triggering without CPU intervention.
Technical Context
The R7F102GBC2DNP#AA0 implements the RL78 CPU core with a 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 32 KB code flash (2 KB block size), 2 KB data flash with background operation (BGO), and 4 KB on-chip RAM - enabling secure firmware updates and real-time data logging without halting program execution.
Peripheral integration centers on low-power autonomy: the SNOOZE mode sequencer executes up to 32 preconfigured commands (e.g., ADC sampling, CTSU measurement, comparison) without waking the CPU or accessing flash/RAM; the Event Link Controller (ELC) enables direct hardware-to-hardware signal routing across 20 event sources, eliminating interrupt latency and software overhead in time-critical control loops.

This wide range eliminates the need for external voltage regulation in many portable designs and simplifies power architecture.
Does the R7F102GBC2DNP#AA0 include hardware-based capacitive touch sensing?
Yes, the R7F102GBC2DNP#AA0 integrates the CTSU2La capacitive touch sensing unit, supporting up to 29 self-capacitance keys or mutual-capacitance matrix configurations. It operates across the full VDD range (1.8–5.5 V) and requires no external components beyond standard decoupling capacitors - reducing BOM cost and PCB area versus discrete touch controllers.
What low-power modes are available on the R7F102GBC2DNP#AA0 and their typical current draw?
The R7F102GBC2DNP#AA0 supports HALT, STOP, and SNOOZE modes. STOP mode draws 200 nA (typ.) with RTC and key interrupts active; HALT mode consumes 1.2 µA (typ.) with RAM retention; SNOOZE mode enables autonomous peripheral operation (e.g., CTSU, ADC) at ~1.5 µA while keeping CPU and flash powered down - extending battery life in intermittent-sensing applications.
Can the R7F102GBC2DNP#AA0 execute code while rewriting data flash memory?
Yes, the R7F102GBC2DNP#AA0 supports Background Operation (BGO) for its 2 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously erasing or programming data flash - essential for reliable field-upgradable calibration data, user preferences, or firmware metadata without system interruption.
What is the maximum number of analog input channels supported by the R7F102GBC2DNP#AA0's ADC?
The R7F102GBC2DNP#AA0 features a 10-bit successive-approximation ADC with up to 10 analog input channels (ANI0–ANI19, depending on pin configuration).
