Product details
Overview
R7F102GEC2DNP#BA0 from Renesas is a 40-pin HWQFN-packaged RL78/G22 16-bit microcontroller with 64 KB code flash, 4 KB RAM, and 2 KB data flash, operating from 1.6 V to 5.5 V. It delivers true low-power performance (37.5 µA/MHz active, 200 nA STOP mode) and integrates capacitive touch sensing for up to 29 keys-ideal for battery-powered consumer HMI applications such as smart remotes and portable appliances.
For engineers reviewing the R7F102GEC2DNP#BA0 datasheet, R7F102GEC2DNP#BA0 pinout, R7F102GEC2DNP#BA0 application, or R7F102GEC2DNP#BA0 equivalent, key selection considerations include its 40-pin HWQFN (6 × 6 mm, 0.50-mm pitch) package, 64 KB flash configuration, -40°C to +85°C temperature grade (D-suffix), and integrated CTSU2La capacitive sensing unit supporting self- and mutual-capacitance modes.
Technical Context
The RL78/G22 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing-from 0.03125 µs at 32 MHz (high-speed on-chip oscillator) to 30.5 µs at 32.768 kHz (subsystem clock). It supports multiply/divide/accumulate instructions and features a 1 MB address space with four banks of eight 8-bit general-purpose registers.
Peripherals include a SNOOZE mode sequencer (SMS) enabling CPU-free low-power periodic processing using 32 programmable steps across 21 command types, plus an Event Link Controller (ELC) routing 20 event signals between peripherals without CPU intervention-critical for deterministic real-time response in ultra-low-power operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102GEE2DNP#BA0 | Same RL78/G22 family, identical 40-pin HWQFN package and 64 KB flash, but rated for industrial -40°C to +105°C (3C suffix vs. D's consumer -40°C to +85°C) | Targeted at industrial environments requiring extended temperature operation-unsuitable where cost-sensitive consumer-grade qualification is mandated | Select R7F102GEE2DNP#BA0 only if ambient operating temperature exceeds +85°C; otherwise R7F102GEC2DNP#BA0 meets full spec at lower cost |
| R7F102GCC2DLA#AC0 | 36-pin WFLGA (4 × 4 mm) package, 32 KB flash, same -40°C to +85°C rating, but lacks P70–P73 KRx pins and one SAU channel | Designed for space-constrained designs with reduced peripheral count-requires PCB redesign and firmware adaptation for pin mapping and feature reduction | Choose R7F102GCC2DLA#AC0 only when board area is critical and 32 KB flash suffices; not drop-in compatible due to package and peripheral differences |
Compared with R7F102GEE2DNP#BA0, the R7F102GEC2DNP#BA0 offers identical core performance and peripherals at lower cost for consumer-temperature applications; compared with R7F102GCC2DLA#AC0, it provides higher flash density, additional KRx touch sense pins, and larger QFN footprint for improved thermal dissipation and layout flexibility.

FAQ
What is the maximum operating frequency and core voltage range supported by the R7F102GEC2DNP#BA0?
The R7F102GEC2DNP#BA0 operates at up to 32 MHz using its high-accuracy ±1.0% on-chip oscillator and supports a supply voltage range of 1.6 V to 5.5 V. This wide VDD range allows direct interfacing with 1.8 V, 2.5 V, and 3.3 V logic families without level shifters, and enables single-supply operation in mixed-voltage systems. The R7F102GEC2DNP#BA0 maintains full functionality-including 64 KB flash access and CTSU2La operation-across the entire voltage range.
Does the R7F102GEC2DNP#BA0 include hardware support for capacitive touch sensing, and how many keys can it manage?
Yes, the R7F102GEC2DNP#BA0 integrates the CTSU2La capacitive touch sensing unit, supporting up to 29 keys via self-capacitance (single-pin per key) or mutual-capacitance (matrix configuration) methods. It operates across the full VDD range (1.8–5.5 V), includes automatic noise cancellation, and can run autonomously in SNOOZE mode-enabling touch detection with no CPU involvement and sub-10 µA active current per scan cycle.
What low-power modes does the R7F102GEC2DNP#BA0 support, and what are their typical current draws?
The R7F102GEC2DNP#BA0 supports HALT mode (0.25 µA typ.), STOP mode (200 nA typ.), and SNOOZE mode. In STOP mode, the CPU, flash, and RAM are halted while CTSU, RTC, and selected peripherals remain active-enabling wake-up in under 3.5 µs. SNOOZE mode allows autonomous CTSU/ADC/timer sequencing without CPU or flash activation, achieving average currents below 1 µA in periodic touch-sensing applications.
How much memory does the R7F102GEC2DNP#BA0 provide, and is data flash accessible during program execution?
The R7F102GEC2DNP#BA0 includes 64 KB of code flash memory, 4 KB of on-chip RAM, and 2 KB of data flash memory. The data flash supports Background Operation (BGO), meaning the CPU can execute instructions from code flash while simultaneously erasing or programming data flash-enabling seamless runtime parameter storage, firmware updates, or logging without interrupting real-time tasks.
What communication interfaces are available on the R7F102GEC2DNP#BA0, and how many instances of each are implemented?
The R7F102GEC2DNP#BA0 provides up to 4 UARTA channels (with LIN support), 6 I2C/Simplified I2C channels, and 5 Simplified SPI (CSI) channels. It also includes a Serial Array Unit (SAU) supporting simultaneous UART/I2C/SPI operation. All interfaces are fully multiplexed across the 40-pin HWQFN package, with flexible pin assignment via the Peripheral I/O Redirection Register (PIOR) to optimize PCB layout and signal integrity.
