Overview
R7F102GEE3CNP#AA0 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G22 microcontroller with 64 KB code flash, 4 KB RAM, and integrated capacitive touch sensing for up to 29 keys. It operates from 1.6–5.5 V, delivers 37.5 µA/MHz active current and 200 nA STOP-mode current, and supports real-time clock, UART, I²C, SPI, and 10-bit ADC - deployed in battery-powered industrial HMI and sensor nodes.
For engineers reviewing the R7F102GEE3CNP#AA0 datasheet, R7F102GEE3CNP#AA0 pinout, R7F102GEE3CNP#AA0 application, or R7F102GEE3CNP#AA0 equivalent, key selection criteria include its 40-pin HWQFN (6 × 6 mm, 0.50-mm pitch) package, 64 KB flash/4 KB RAM memory configuration, -40 to +85°C temperature grade, and support for SNOOZE mode sequencer and CTSU2La capacitive sensing unit.
Technical Context
The R7F102GEE3CNP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It integrates a SNOOZE mode sequencer (SMS) supporting 32 sequential low-power processes using 21 command types without CPU involvement.
Peripheral integration includes an Event Link Controller (ELC) routing 20 event signals between peripherals, Data Transfer Controller (DTC) with chain transfer, and dual I²C interfaces (IICA0/IICA1), four UARTA channels, and five CSI/SPI channels - all accessible via multiplexed pins on the 40-pin HWQFN footprint.

FAQ
What is the package type and pin count of the R7F102GEE3CNP#AA0?
The R7F102GEE3CNP#AA0 uses a 40-pin HWQFN package with 6 × 6 mm body size and 0.50-mm pitch. It features an exposed die pad recommended to be connected to VSS for thermal and electrical performance. This matches the RL78/G22 40-pin variant defined in Renesas document R01DS0424EJ0120.
Does the R7F102GEE3CNP#AA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F102GEE3CNP#AA0 integrates the CTSU2La capacitive touch sensing unit supporting up to 29 keys. It operates in both self-capacitance mode (one pin per key) and mutual-capacitance matrix mode (transmit/receive pin pairs), with full support for noise suppression and automatic calibration - all implemented without external components.
What are the memory resources available on the R7F102GEE3CNP#AA0?
The R7F102GEE3CNP#AA0 provides 64 KB of code flash memory, 2 KB of data flash memory, and 4 KB of on-chip RAM. The data flash supports Background Operation (BGO), allowing program execution from code flash while simultaneously rewriting data flash - essential for reliable parameter storage in field-deployed devices.
What low-power modes does the R7F102GEE3CNP#AA0 support, and what are their typical current draws?
The R7F102GEE3CNP#AA0 supports HALT, STOP, and SNOOZE modes. STOP mode draws 200 nA (typ.), with wakeup in under 4 µs. SNOOZE mode enables autonomous peripheral sequencing (e.g., ADC, CTSU) without CPU, flash, or RAM activation - reducing average current in periodic-sensing applications well below 1 µA.
