Product details
Overview
R7F102GAE2DSP#AA0 from Renesas is a 30-pin, 64-KB flash, 4-KB RAM RL78/G22 16-bit microcontroller with ultra-low-power operation (37.5 µA/MHz active, 200 nA STOP), integrated capacitive touch sensing (up to 29 keys), 10-bit ADC (10 channels), RTC, and dual UART/I²C/SPI interfaces. It targets battery-powered HMI and industrial control nodes requiring long runtime and robust touch interface.
For engineers reviewing the R7F102GAE2DSP#AA0 datasheet, R7F102GAE2DSP#AA0 pinout, R7F102GAE2DSP#AA0 application, or R7F102GAE2DSP#AA0 equivalent, this page delivers verified package mapping (30-pin LSSOP), confirmed pin functions including TSCAP/RTC1HZ/SCL11 on P30 and TS11–TS18 for CTSU, real-world power modes (HALT/STOP/SNOOZE), and two validated alternative parts with documented functional trade-offs.
Technical Context
The R7F102GAE2DSP#AA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 low-power background processes without CPU, flash, or RAM activation.
It integrates a 10-bit ADC with internal 1.48-V reference and temperature sensor, dual I²C interfaces (IICA0/IICA1), four UARTA channels (including LIN support), and a 16-bit timer array unit with 8 channels - all operating across 1.6–5.5 V supply and -40°C to +85°C ambient range.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R7F102GAE2DSP#AA0?
The R7F102GAE2DSP#AA0 operates up to 32 MHz using its high-speed on-chip oscillator, with guaranteed functionality across 1.6 V to 5.5 V supply. At 32 MHz, minimum instruction execution time is 0.03125 µs; the device maintains full peripheral operation including CTSU and ADC within this voltage range per R01DS0424EJ0120 Rev.1.20 specifications.
Does the R7F102GAE2DSP#AA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F102GAE2DSP#AA0 integrates the CTSU2La unit supporting up to 29 self-capacitance keys or matrix mutual-capacitance configurations. It requires only external RC network tuning (no dedicated touch ASIC), and operates across 1.8–5.5 V VDD with built-in noise suppression algorithms confirmed in the RL78/G22 datasheet.
How many I²C interfaces does the R7F102GAE2DSP#AA0 provide, and are they electrically isolated?
The R7F102GAE2DSP#AA0 provides two independent I²C interfaces: IICA0 (pins P10/P11) and IICA1 (pins P30/P17). They operate concurrently at up to 400 kHz, share no internal bus resources, and have separate clock/data registers - enabling simultaneous communication with multiple slaves without software arbitration.
What debug interface is supported by the R7F102GAE2DSP#AA0, and which pins are required?
The R7F102GAE2DSP#AA0 supports Renesas E2/E2 Lite emulator debugging via the TOOL0 pin (P40) and RESET pin. No additional SWD/JTAG pins are required - the single-wire debug interface uses P40 for bidirectional communication, minimizing PCB routing overhead while supporting full flash programming and real-time trace.
Is the R7F102GAE2DSP#AA0 qualified for industrial temperature range, and what is the specified ambient operating limit?
Yes, the R7F102GAE2DSP#AA0 is rated for industrial ambient temperature operation from -40°C to +85°C, as indicated by the '2' suffix in its ordering code (R7F102GAE2DSP#AA0). This qualification covers all specified electrical characteristics including CTSU sensitivity, ADC accuracy, and oscillator stability per the RL78/G22 datasheet Rev.1.20.
