Product details
Overview
R7F102GAE3CSP#AA0 from Renesas is a 30-pin LSSOP-packaged RL78/G22 16-bit microcontroller featuring 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. It operates from 1.6 V to 5.5 V with ultra-low power consumption (37.5 µA/MHz active, 200 nA STOP mode) and supports industrial temperature range (−40°C to +105°C), targeting battery-powered HMI and sensor-edge control applications.
For engineers reviewing the R7F102GAE3CSP#AA0 datasheet, R7F102GAE3CSP#AA0 pinout, R7F102GAE3CSP#AA0 application, or R7F102GAE3CSP#AA0 equivalent, key selection considerations include its 30-pin LSSOP package, 64 KB flash/4 KB RAM configuration, CTSU2La capacitive touch unit, RTC with alarm, and dual UART/I²C/SPI interface support for compact industrial control nodes.
Technical Context
The R7F102GAE3CSP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 µs at 32 MHz high-speed mode or 30.5 µs at 32.768 kHz ultra-low-speed mode). It integrates SNOOZE mode sequencer (SMS) for autonomous low-power sensor polling without CPU wake-up.
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/repeat transfer modes, and CTSU2La capacitive touch unit supporting both self- and mutual-capacitance configurations across 30 dedicated TSx pins - all operating within the 1.6–5.5 V supply range and −40°C to +105°C ambient.

The R7F102GAE3CSP#AA0 supports up to 32 MHz operation using the high-speed on-chip oscillator, with guaranteed functionality across its full 1.6 V to 5.5 V supply range. At 32 MHz, minimum instruction execution time is 0.03125 µs; accuracy is ±1.0% over −40°C to +85°C and VDD = 1.8–5.5 V.
Does the R7F102GAE3CSP#AA0 support hardware-based capacitive touch sensing without external components?
Yes, the R7F102GAE3CSP#AA0 integrates the CTSU2La capacitive touch sensing unit, which requires no external RC networks or dedicated touch controller ICs. It supports up to 29 self-capacitance keys or matrix mutual-capacitance configurations using standard GPIO pins configured as TSx channels.
How many UART, I²C, and SPI interfaces does the R7F102GAE3CSP#AA0 provide, and are they independently configurable?
The R7F102GAE3CSP#AA0 provides up to four UARTA channels (one with LIN support), six I²C/Simplified I²C channels, and five CSI (SPI-compatible) channels. All are independently configurable via the Event Link Controller (ELC) and peripheral I/O redirection register (PIOR), allowing flexible pin assignment without hardware redesign.
What is the purpose and capability of the SNOOZE mode sequencer (SMS) in the R7F102GAE3CSP#AA0?
The SNOOZE mode sequencer (SMS) in the R7F102GAE3CSP#AA0 executes up to 32 pre-programmed commands - including ADC conversions, CTSU scans, comparisons, and memory writes - autonomously while the CPU, flash, and RAM remain powered down. This reduces average system current by eliminating periodic wake-ups for routine sensing tasks.
Is the R7F102GAE3CSP#AA0 qualified for industrial temperature operation, and what is its specified ambient range?
Yes, the R7F102GAE3CSP#AA0 is qualified for industrial applications with an ambient operating temperature range of −40°C to +105°C, as indicated by the '3' in the part number suffix (R7F102GAE3CSP#AA0).
