Product details
Overview
R7F102GGE2DNP#AA0 from Renesas is a 48-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 to 5.5 V. It delivers true low-power operation (37.5 µA/MHz active, 200 nA STOP mode), integrates up to 29 capacitive touch sensors, and supports UART, I²C, SPI, RTC, and 16-bit timers - deployed in battery-powered consumer HMI systems.
For engineers reviewing the R7F102GGE2DNP#AA0 datasheet, R7F102GGE2DNP#AA0 pinout, R7F102GGE2DNP#AA0 application, or R7F102GGE2DNP#AA0 equivalent, key selection criteria include its 48-pin HWQFN-0.5 mm pitch package, -40°C to +85°C consumer-grade temperature range, 64 KB flash capacity, integrated CTSU2La capacitive sensing unit, and SNOOZE mode sequencer for ultra-low-power sensor polling without CPU wake-up.
Technical Context
The R7F102GGE2DNP#AA0 implements the RL78 CPU core with 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 64 KB code flash (2 KB block size), 2 KB data flash with background operation (BGO), and 4 KB on-chip RAM.
Peripheral integration includes a 10-bit A/D converter (up to 10 channels), real-time clock with alarm and correction, watchdog timer, event link controller (ELC) for 20 configurable peripheral event links, and SNOOZE mode sequencer capable of executing 32 sequential commands across 21 supported instructions - all while keeping CPU, flash, and RAM powered down.

The R7F102GGE2DNP#AA0 supports up to 32 MHz operation using its high-speed on-chip oscillator, with guaranteed functionality across its full 1.6 V to 5.5 V VDD range. At 32 MHz, minimum instruction execution time is 0.03125 µs; voltage tolerance and timing margins are validated per Renesas R01DS0424EJ0120 datasheet Section 17.1.
Does the R7F102GGE2DNP#AA0 support hardware-accelerated capacitive touch sensing, and how many electrodes can it manage?
Yes, the R7F102GGE2DNP#AA0 integrates the CTSU2La capacitive sensing unit supporting up to 29 electrodes. It operates in self-capacitance mode (one pin per key) or mutual-capacitance matrix configurations, with full hardware acceleration and immunity to supply voltage variation between 1.8 V and 5.5 V.
What packaging and thermal specifications apply to the R7F102GGE2DNP#AA0?
The R7F102GGE2DNP#AA0 uses a 48-pin HWQFN package (7 × 7 mm, 0.50-mm pitch) with exposed die pad, rated for -40°C to +85°C ambient operation. The "D" in the part number denotes consumer-grade temperature range, and the "NP" suffix confirms HWQFN packaging per Renesas ordering guide Table 1-1.
How does the SNOOZE mode sequencer (SMS) in the R7F102GGE2DNP#AA0 reduce system power consumption?
The SMS in the R7F102GGE2DNP#AA0 executes up to 32 predefined operations - such as CTSU scans, ADC conversions, or register comparisons - without waking the CPU, flash, or RAM. This enables autonomous, low-power periodic sensing (e.g., every 500 ms) while maintaining sub-µA average current draw in STOP mode.
Can the R7F102GGE2DNP#AA0 perform background data flash writes while executing application code from main flash memory?
Yes, the R7F102GGE2DNP#AA0 supports background operation (BGO) for its 2 KB data flash. Instructions continue executing from program memory during data flash erase/write cycles, enabling seamless runtime parameter updates, logging, or calibration storage without interrupting real-time tasks.
