Product details
Overview
R7F102GBE2DFP#AA0 from Renesas is a 32-pin LQFP-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 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 industrial HMI and sensor nodes.
For engineers reviewing the R7F102GBE2DFP#AA0 datasheet, R7F102GBE2DFP#AA0 pinout, R7F102GBE2DFP#AA0 application, or R7F102GBE2DFP#AA0 equivalent, key selection criteria include its 64 KB flash capacity, LQFP-32 package with 0.80-mm pitch, -40°C to +85°C temperature grade, integrated CTSU2La capacitive sensing unit, and SNOOZE mode sequencer for ultra-low-power event-driven wake-up without CPU involvement.
Technical Context
The RL78/G22 core implements a 3-stage pipeline CISC architecture with configurable instruction timing: 0.03125 µs at 32 MHz (high-speed on-chip oscillator) or 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.
Power management includes HALT, STOP, and SNOOZE modes; STOP mode enables high-speed wakeup, while SNOOZE mode sequencer executes up to 32 processes using 21 command types - all without CPU, flash, or RAM activation. The Event Link Controller (ELC) routes 20 event signals between peripherals for deterministic, low-latency hardware-triggered operations.

FAQ
What is the maximum operating frequency and clock accuracy of the R7F102GBE2DFP#AA0?
The R7F102GBE2DFP#AA0 supports up to 32 MHz operation using its high-speed on-chip oscillator, which maintains ±1.0% accuracy across VDD = 1.8–5.5 V and TA = -20°C to +85°C. External crystal options (X1/X2) enable higher precision timing, and the 32.768 kHz subsystem oscillator provides RTC-grade accuracy with adjustability.
Does the R7F102GBE2DFP#AA0 support in-system programming and debugging?
Yes, the R7F102GBE2DFP#AA0 supports full in-system programming and debugging via the on-chip debug interface using Renesas E2 or E2 Lite emulators. Pins P40 (TOOL0), P11 (TOOLRxD), and P12 (TOOLTxD) provide dedicated debug connectivity without consuming general-purpose I/O resources.
How many capacitive touch channels does the R7F102GBE2DFP#AA0 support, and what methods are available?
The R7F102GBE2DFP#AA0 integrates the CTSU2La unit supporting up to 29 capacitive touch channels. It supports both self-capacitance (one pin per key) and mutual-capacitance (transmit/receive pin pairs) configurations, enabling flexible button, slider, and matrix keypad implementations with built-in noise rejection and drift compensation.
What are the power supply requirements and low-power capabilities of the R7F102GBE2DFP#AA0?
The R7F102GBE2DFP#AA0 operates from a single 1.6 V to 5.5 V supply. Its ultra-low-power design achieves 37.5 µA/MHz active current, 200 nA STOP mode current, and supports HALT, STOP, and SNOOZE modes. A 0.47–1 µF capacitor must be placed between REGC and VSS to stabilize the internal regulator.
Is the R7F102GBE2DFP#AA0 pin-compatible with other RL78/G22 variants in LQFP-32 package?
Yes, all RL78/G22 devices in the 32-pin LQFP package (e.g., R7F102GBC2DFP, R7F102GBE3CFP) share identical pinouts and electrical characteristics. Firmware and hardware designs are interchangeable across flash size (32/64 KB) and temperature grade (-40°C to +85°C or +105°C) variants - only flash content and qualification differ.
