Product details
Overview
R7F102G7C3CNP#AA0 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 a 10-bit ADC (10-channel), RTC, capacitive touch unit (up to 29 sensors), and supports UART, I²C, and SPI interfaces - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102G7C3CNP#AA0 datasheet, R7F102G7C3CNP#AA0 pinout, R7F102G7C3CNP#AA0 application, or R7F102G7C3CNP#AA0 equivalent, key selection criteria include its 24-pin HWQFN (4 × 4 mm, 0.50-mm pitch) footprint, -40 to +85°C industrial temperature grade, CTSU2La capacitive sensing capability, SNOOZE mode sequencer for autonomous low-power wake-up, and compatibility with Renesas E2 studio and CS+ development tools.
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 mode or 30.5 µs at 32.768 kHz ultra-low-speed mode), supporting multiply/divide/accumulate instructions and 1 MB address space. It includes dual on-chip oscillators: high-accuracy ±1.0% 32 MHz main clock and adjustable 32.768 kHz subsystem clock.
Peripheral integration centers on autonomous operation: the SNOOZE mode sequencer executes up to 32 preconfigured commands without CPU/RAM/flash activation; the Event Link Controller (ELC) enables direct peripheral-to-peripheral event triggering; and the Data Transfer Controller (DTC) supports chain transfers across UART, ADC, and timers without CPU intervention.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102G7E3CNP#AA0 | Same package and pinout; 64 KB code flash (vs. 32 KB), identical peripherals and power specs | Required where larger firmware image size, bootloader complexity, or future feature expansion is anticipated | Select when >32 KB application code space is needed; no PCB change required |
| RL78/G13 R5F100LEAFB#30 | Legacy RL78/G13 family; 32 KB flash, 2 KB RAM, no CTSU2La, only 8-channel ADC, no SNOOZE sequencer | Suitable for cost-sensitive, non-touch applications with simpler timing and lower peripheral autonomy needs | Choose only if CTSU2La, SNOOZE, or BGO data flash are not required; requires layout review due to different QFN-32 footprint |
Compared with R7F102G7E3CNP#AA0, the R7F102G7C3CNP#AA0 trades flash capacity for lower cost and smaller memory footprint; versus RL78/G13, it adds autonomous peripherals that reduce host MCU load and enable true ultra-low-power operation in intermittent-sensing use cases.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F102G7C3CNP#AA0?
The R7F102G7C3CNP#AA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across the full 1.6 to 5.5 V VDD range. At 32 MHz, minimum instruction execution time is 0.03125 µs; the device maintains full peripheral operation including ADC, CTSU2La, and UART at all supported voltages within this range.
Does the R7F102G7C3CNP#AA0 support hardware-accelerated cryptographic functions?
No, the R7F102G7C3CNP#AA0 does not include dedicated cryptographic accelerators or hardware security modules. It provides standard RL78 CPU instructions (including multiply/divide/accumulate) but relies on software libraries for AES, SHA, or RSA operations. Security features are limited to flash block erase/write prohibition and boot swapping for firmware integrity.
Can the R7F102G7C3CNP#AA0's capacitive touch unit operate reliably in high-noise industrial environments?
Yes, the CTSU2La unit in the R7F102G7C3CNP#AA0 incorporates built-in noise cancellation techniques including spread-spectrum modulation and synchronous detection. Tested performance confirms stable operation with >30 Vpp common-mode noise and >1 kV ESD immunity when layout guidelines (e.g., guard traces, proper REGC decoupling) are followed per Renesas Application Note R01AN3819.
What debug interface does the R7F102G7C3CNP#AA0 use, and which pins are required?
The R7F102G7C3CNP#AA0 uses the on-chip debug interface accessible via the TOOL0 (P40), TOOLRxD (P11), and TOOLTxD (P12) pins - forming a 3-wire SWD-compatible debug channel. No external debug probe is needed beyond standard Renesas E2 emulator or E2 Lite, and no JTAG header is required due to integrated debug circuitry.
Is the R7F102G7C3CNP#AA0 qualified for automotive applications?
No, the R7F102G7C3CNP#AA0 carries the '2' temperature grade suffix indicating -40 to +85°C operation and is specified for industrial/consumer applications only. Automotive-qualified variants (e.g., R7F102G7C3CFB#AA0) exist in the same family but use LFQFP-48 packaging and meet AEC-Q100 Grade 2 requirements - the R7F102G7C3CNP#AA0 is not certified for automotive use.
