Product details
Overview
R7F102GGE2DFB#AA0 from Renesas is a 48-pin LFQFP, 5.5-V tolerant RL78/G22 16-bit microcontroller with 64 KB code flash, 4 KB RAM, and integrated capacitive touch sensing for up to 29 keys. It operates from 1.6 V to 5.5 V, delivers 37.5 µA/MHz active current and 200 nA STOP mode current, and supports industrial temperature range (−40°C to +105°C). It targets low-power HMI and sensor-edge applications such as smart thermostats and industrial control panels.
For engineers reviewing the R7F102GGE2DFB#AA0 datasheet, R7F102GGE2DFB#AA0 pinout, R7F102GGE2DFB#AA0 application, or R7F102GGE2DFB#AA0 equivalent, key selection factors include its 48-pin LFQFP-0.5 mm pitch package, 64 KB flash/4 KB RAM configuration, CTSU2La capacitive touch unit, RTC with alarm, and dual I²C/SPI/UART interfaces supporting LIN-bus.
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 integrates a SNOOZE mode sequencer (SMS) enabling CPU-free periodic wake-up and sensor polling using 21 command types across 32 processes.
Peripheral integration includes an Event Link Controller (ELC) routing 20 event signals between peripherals, a Data Transfer Controller (DTC) supporting chain transfer, and a 10-bit A/D converter with internal 1.48 V reference and temperature sensor. The CTSU2La unit supports both self- and mutual-capacitance methods with dedicated TSCAP pin and up to 29 sensing channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F102GGC2DFB | 32 KB code flash, same 48-pin LFQFP package, identical peripherals and temperature grade. | Lower memory footprint suits simpler HMI or fixed-function sensor nodes without field-upgrade requirements. | Select when firmware size remains under 32 KB and cost optimization is prioritized over future feature expansion. |
| R7F102GGE3CFB | Same 64 KB flash and peripherals but in 48-pin LQFP (0.80-mm pitch) package; no exposed die pad. | Better manufacturability in legacy SMT lines not equipped for 0.5-mm pitch; slightly higher thermal resistance limits high-duty-cycle operation. | Choose for compatibility with existing LQFP reflow profiles or where thermal dissipation is non-critical. |
Compared with R7F102GGE2DFB#AA0, R7F102GGC2DFB trades flash capacity for lower unit cost in static applications, while R7F102GGE3CFB substitutes finer-pitch packaging for broader assembly flexibility-neither offers pin-to-pin compatibility due to differing pitch and thermal pad requirements.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F102GGE2DFB#AA0?
The R7F102GGE2DFB#AA0 supports a maximum system clock of 32 MHz using the high-speed on-chip oscillator and operates across a supply voltage range of 1.6 V to 5.5 V. Its 5.5 V tolerance allows direct interfacing with 5 V logic and USB-powered systems without level-shifting circuitry.
Does the R7F102GGE2DFB#AA0 include hardware support for capacitive touch sensing?
Yes, the R7F102GGE2DFB#AA0 integrates the CTSU2La capacitive touch sensing unit, supporting up to 29 keys using either self-capacitance (one pin per key) or mutual-capacitance (matrix) configurations. It includes dedicated TSCAP pin and operates reliably from 1.8 V to 5.5 V.
How does the SNOOZE mode sequencer (SMS) function in the R7F102GGE2DFB#AA0?
The SNOOZE mode sequencer in the R7F102GGE2DFB#AA0 executes up to 32 pre-programmed operations-including ADC conversions, CTSU scans, and register comparisons-without waking the CPU, flash, or RAM. This reduces average power consumption significantly in periodic sensor monitoring tasks.
What are the key differences between R7F102GGE2DFB#AA0 and R7F102GGC2DFB?
The R7F102GGE2DFB#AA0 features 64 KB code flash, while R7F102GGC2DFB has 32 KB flash. Both share identical 48-pin LFQFP-0.5 mm packaging, industrial temperature range (−40°C to +105°C), and peripheral sets. Memory size is the primary differentiator for firmware scalability.
Is an external crystal required for real-time clock operation in the R7F102GGE2DFB#AA0?
No, the R7F102GGE2DFB#AA0 includes a low-speed on-chip oscillator calibrated to 32.768 kHz (typ.) for RTC operation. An external 32.768 kHz crystal may be used via P121/P122 pins for higher accuracy, but it is optional-not required-for basic calendar and alarm functionality.
