Product details
Overview
R7F102GGE2DFB#BA0 from Renesas is a 48-pin LFQFP, industrial-grade (−40 to +105°C) RL78/G22 16-bit MCU with 64 KB code flash, 4 KB RAM, 2 KB data flash, 10-channel 10-bit ADC, and integrated capacitive touch sensing for up to 29 keys - deployed in battery-powered smart sensors and industrial HMI control panels.
For engineers reviewing the R7F102GGE2DFB#BA0 datasheet, R7F102GGE2DFB#BA0 pinout, R7F102GGE2DFB#BA0 application, or R7F102GGE2DFB#BA0 equivalent, key selection criteria include its 200-nA STOP mode current, 37.5-µA/MHz active power, 32.768-kHz RTC with alarm, SNOOZE mode sequencer for autonomous low-power sensing, and dual I²C/SPI/UART interfaces supporting LIN bus.
Technical Context
The R7F102GGE2DFB#BA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates a 21-command SNOOZE mode sequencer that executes sensor polling and threshold comparisons without CPU wake-up.
Peripheral integration includes an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat transfer modes, and CTSU2La capacitive touch unit supporting self- and mutual-capacitance configurations - all operating within 1.6–5.5 V supply range and qualified for industrial ambient temperatures.

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 | Same 48-pin LFQFP package and RL78/G22 core, but with 32 KB code flash and identical 4 KB RAM/2 KB data flash | Targeted at cost-optimized designs where firmware size ≤30 KB; retains all peripherals including CTSU2La and SNOOZE sequencer | Select when firmware footprint permits reduction - saves ~15% BOM cost without sacrificing touch, RTC, or low-power features |
| R7F102GFE2DFB | 44-pin LQFP variant with same 64 KB flash, 4 KB RAM, and full peripheral set - excludes P62, P70–P73, and two TS pins vs. R7F102GGE2DFB#BA0 | Suitable for space-constrained layouts requiring fewer I/Os; lacks four touch-capable pins and one dedicated KR input for key scanning | Choose when board area is critical and 44-pin footprint suffices - retains full UART/I²C/SPI count and RTC functionality |
Compared with R7F102GGC2DFB and R7F102GFE2DFB, the R7F102GGE2DFB#BA0 delivers maximum I/O flexibility (48 pins), full touch pin count (29), and largest code density (64 KB) - making it optimal for feature-rich industrial HMI and sensor fusion nodes where peripheral headroom and future firmware scalability are essential.

FAQ
What is the operating temperature range for the R7F102GGE2DFB#BA0?
The R7F102GGE2DFB#BA0 is rated for industrial ambient operation from −40°C to +105°C. This rating is confirmed in the RL78/G22 datasheet (R01DS0424EJ0120 Rev.1.20, Page 1) under "Operating ambient temperature" for 3C-grade devices, and matches the "3" suffix in the part number's temperature code field.
Does the R7F102GGE2DFB#BA0 support capacitive touch sensing?
Yes, the R7F102GGE2DFB#BA0 integrates the CTSU2La capacitive touch sensing unit and supports up to 29 keys via self-capacitance or mutual-capacitance configurations. Pin assignments include dedicated TSxx pins (e.g., P10–P17, P20–P25, P30/TSCAP, P147) documented in Table 1-10 of the datasheet.
What are the memory resources available on the R7F102GGE2DFB#BA0?
The R7F102GGE2DFB#BA0 provides 64 KB of code flash memory (organized in 2-KB blocks), 2 KB of data flash memory rated for 1,000,000 write/erase cycles, and 4 KB of on-chip RAM. These values are specified in Section 1.1 "Features" and Table 1-1 of the RL78/G22 datasheet.
Which oscillator options does the R7F102GGE2DFB#BA0 support?
The R7F102GGE2DFB#BA0 supports three on-chip oscillators: high-speed (32/24/16/12/8/6/4/3/2/1 MHz, ±1.0%), middle-speed (4/2/1 MHz, adjustable), and low-speed (32.768 kHz, adjustable), plus external crystal (X1/X2) and external clock (EXCLK/XT1/XT2) inputs - all detailed in Section 1.1 "Features".
Is the R7F102GGE2DFB#BA0 pin-compatible with other RL78/G22 variants?
No - the R7F102GGE2DFB#BA0 uses a 48-pin LFQFP (0.50-mm pitch) package. While other RL78/G22 parts share the same core and peripheral IP, pin compatibility is limited to identical package types (e.g., R7F102GFE2DFB is 44-pin LQFP, not pin-compatible). Pin functions are defined per package in Tables 1-2 through 1-10.
