Product details
Overview
R7F102GBE2DNP#AA0 from Renesas is a 32-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 ultra-low power consumption (37.5 µA/MHz active, 200 nA STOP mode), integrates 10-channel 10-bit ADC, RTC, capacitive touch sensing (up to 29 keys), and supports UART, I²C, and SPI interfaces for battery-powered consumer HMI applications.
For engineers reviewing the R7F102GBE2DNP#AA0 datasheet, R7F102GBE2DNP#AA0 pinout, R7F102GBE2DNP#AA0 application, or R7F102GBE2DNP#AA0 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.50-mm pitch) package, -40 to +85°C temperature grade, 64 KB flash capacity, integrated CTSU2La capacitive touch unit, and SNOOZE mode sequencer for autonomous low-power sensor polling.
Technical Context
The R7F102GBE2DNP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It includes dedicated hardware accelerators for multiply/divide/accumulate operations and a 1 MB address space.
Its peripheral set centers on ultra-low-power operation: the SNOOZE mode sequencer executes up to 32 programmable commands without CPU, flash, or RAM involvement; the Event Link Controller (ELC) enables direct peripheral-to-peripheral event triggering; and the Data Transfer Controller (DTC) supports chain transfer for efficient memory-mapped peripheral handling.

FAQ
What is the maximum operating frequency and voltage range for the R7F102GBE2DNP#AA0?
The R7F102GBE2DNP#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a wide supply voltage range of 1.6 V to 5.5 V. Its ±1.0% oscillator accuracy (at VDD = 1.8–5.5 V, TA = –20 to +85°C) ensures reliable timing for UART, I²C, and SPI communications without external crystals in many applications. The R7F102GBE2DNP#AA0 maintains full functionality across this entire voltage range.
Does the R7F102GBE2DNP#AA0 support capacitive touch sensing, and how many keys can it handle?
Yes, the R7F102GBE2DNP#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 mode (matrix configuration using dedicated TX/RX pins). The unit functions across the full 1.8–5.5 V VDD range and includes built-in noise rejection features-eliminating the need for external touch controller ICs in applications like appliance control panels or remote controls.
What low-power modes does the R7F102GBE2DNP#AA0 offer, and what are their typical current draws?
The R7F102GBE2DNP#AA0 provides HALT, STOP, and SNOOZE modes. In STOP mode, it draws just 200 nA (typ.) with RTC and key interrupts enabled; in active mode, it consumes 37.5 µA/MHz. The SNOOZE mode sequencer allows autonomous execution of sensor polling or timer-based tasks without waking the CPU, flash, or RAM-delivering deeper power savings than conventional sleep modes. The R7F102GBE2DNP#AA0 achieves these values without external components.
Can the R7F102GBE2DNP#AA0 execute code while rewriting data flash memory?
Yes, the R7F102GBE2DNP#AA0 supports Background Operation (BGO) for data flash memory, allowing the CPU to execute instructions from program memory while simultaneously rewriting the 2 KB data flash. This capability enables seamless firmware parameter updates, data logging, or calibration storage without halting application execution. The R7F102GBE2DNP#AA0 guarantees 1,000,000 write/erase cycles (typ.) for the data flash region.
What debug interface does the R7F102GBE2DNP#AA0 use, and which pins are required?
The R7F102GBE2DNP#AA0 uses Renesas' on-chip debugging interface accessed via the TOOL0 (P40), TOOLRxD (P11), and TOOLTxD (P12) pins. These three pins support full debug functionality-including breakpoint setting, register inspection, and flash programming-using standard Renesas E2 emulator hardware. No additional debug header or SWD/JTAG adapter is needed, simplifying development setup for the R7F102GBE2DNP#AA0.
