Product details
Overview
R7F102GEE2DNP#AA0 from Renesas is a 40-pin HWQFN-packaged RL78/G22 16-bit microcontroller with 64 KB code flash, 4 KB RAM, and integrated capacitive touch sensing for up to 29 keys. It operates from 1.6 V to 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 consumer HMI systems.
For engineers reviewing the R7F102GEE2DNP#AA0 datasheet, R7F102GEE2DNP#AA0 pinout, R7F102GEE2DNP#AA0 application, or R7F102GEE2DNP#AA0 equivalent, this page provides verified package mapping (HWQFN-40, 6×6 mm, 0.50-mm pitch), confirmed low-power operating modes (HALT/STOP/SNOOZE), validated CTSU2La touch channel count, and real-world timing/peripheral constraints for rapid integration into cost-sensitive, energy-constrained designs.
Technical Context
The RL78 CPU core implements a 3-stage pipeline CISC architecture with configurable instruction execution time (0.03125 µs at 32 MHz high-speed mode; 30.5 µs at 32.768 kHz ultra-low-speed mode) and supports multiply/divide/MAC instructions. Its memory subsystem includes 64 KB code flash (2 KB block size), 2 KB data flash with background operation (BGO), and 4 KB on-chip RAM.
Peripheral integration centers on ultra-low-power operation: SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands without CPU/RAM/flash activation; Event Link Controller (ELC) enables direct peripheral-to-peripheral event triggering; and Capacitive Sensing Unit (CTSU2La) supports self- and mutual-capacitance configurations with dedicated TSCAP and TSxx pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102GEC2DNP | Same RL78/G22 family, 32 KB code flash (vs. 64 KB), identical 40-pin HWQFN package and peripheral set | Targeted at cost-optimized designs where firmware size ≤30 KB and no future feature expansion is planned | Select when flash headroom is not required and BOM cost reduction is prioritized over field-upgrade flexibility |
| R7F102GBE2DNP | 32-pin HWQFN variant with 64 KB flash but only 32 I/O pins and reduced analog channel count (6 vs. 10 ADC inputs) | Suitable for space-constrained PCBs where full 40-pin I/O and 10-channel sensing are unnecessary | Choose for compact layouts needing fewer peripherals - verify CTSU2La pin availability matches key count requirements |
Compared with R7F102GEE2DNP#AA0, R7F102GEC2DNP trades flash capacity for lower unit cost without sacrificing package or peripheral compatibility, while R7F102GBE2DNP reduces pin count and analog resources to fit smaller footprints - both require validation of touch channel allocation and flash usage margins.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for R7F102GEE2DNP#AA0?
R7F102GEE2DNP#AA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6 V to 5.5 V supply range. At 32 MHz, the minimum instruction execution time is 0.03125 µs; voltage scaling does not throttle clock speed, unlike many competing MCUs.
Does R7F102GEE2DNP#AA0 support true hardware-based capacitive touch sensing without CPU intervention?
Yes, R7F102GEE2DNP#AA0 integrates the CTSU2La unit which performs charge-transfer-based capacitive sensing autonomously. Combined with the SNOOZE mode sequencer, it can execute full touch scans, baseline updates, and threshold comparisons without CPU involvement - reducing active current to zero during sensing intervals.
How many unique touch sensing channels does R7F102GEE2DNP#AA0 support, and what configuration options are available?
R7F102GEE2DNP#AA0 supports up to 29 distinct touch keys via its CTSU2La unit. It offers both self-capacitance mode (one pin per key) and mutual-capacitance matrix mode (separate TX/RX pins selected from up to 29 available TSxx pins), enabling flexible overlay design from simple buttons to multi-touch sliders.
What debug and programming interfaces are available on R7F102GEE2DNP#AA0?
R7F102GEE2DNP#AA0 provides a single-wire debug interface via the TOOL0 (P40) pin, compatible with Renesas E2 studio and E2 emulator. It supports full on-chip debugging, flash programming, and real-time trace - no JTAG header or additional pins required, simplifying PCB layout and test fixture design.
Is R7F102GEE2DNP#AA0 qualified for industrial temperature operation, and what is its specified ambient range?
R7F102GEE2DNP#AA0 is rated for consumer applications with an ambient operating temperature range of –40 °C to +85 °C (denoted by "2D" in Renesas part numbering). For industrial-grade operation up to +105 °C, the "3C" suffix variant (e.g., R7F102GEE3CNP) must be selected - R7F102GEE2DNP#AA0 is not qualified beyond +85 °C.
