Product details
Overview
R7F100GAJ2DSP#AA0 from Renesas is a 32-bit RL78/G23 microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating at 1.6–5.5 V and supporting -40 to +85°C ambient temperature. It integrates capacitive touch sensing (CTSU2L), 12-bit A/D converter (26 channels), UARTA/SPI/I²C interfaces, RTC, and ultra-low-power STOP mode (210 nA data retention). It targets battery-powered consumer HMI and sensor-edge applications.
For engineers reviewing the R7F100GAJ2DSP#AA0 datasheet, R7F100GAJ2DSP#AA0 pinout, R7F100GAJ2DSP#AA0 application, or R7F100GAJ2DSP#AA0 equivalent, key selection criteria include its 32-pin HWQFN package, 256 KB flash/24 KB RAM memory configuration, CTSU2L-based touch interface capability, and support for SNOOZE mode sequencer for autonomous low-power sensor polling.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs min @ 32 MHz or 30.5 µs @ 32.768 kHz), enabling dynamic performance/power trade-offs. Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparator evaluation, and register comparison-without CPU, RAM, or flash activation.
Peripheral integration includes an Event Link Controller (ELCL) for hardware-triggered signal routing between modules (e.g., timer overflow → ADC start), and a Data Transfer Controller (DTC) supporting chain transfers across UART, SPI, and memory-reducing CPU load during burst data acquisition.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R7F100GAJ2DSP#AA0?
The R7F100GAJ2DSP#AA0 operates up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy). At this frequency, typical active current is 41 µA/MHz, resulting in ~1.3 mA total at full speed with all peripherals enabled. STOP mode draws only 210 nA while retaining 4 KB of RAM-critical for ultra-low-power wake-on-event designs.
Does the R7F100GAJ2DSP#AA0 support hardware-accelerated capacitive touch sensing, and what configurations are available?
Yes, the R7F100GAJ2DSP#AA0 integrates the CTSU2L capacitive touch unit supporting both self-capacitance (up to 32 independent keys) and mutual-capacitance (8×8 matrix, up to 64 keys). It operates across the full 1.8–5.5 V supply range and includes hardware noise cancellation-eliminating the need for external touch controllers in consumer HMI applications.
How many serial communication interfaces does the R7F100GAJ2DSP#AA0 provide, and which protocols are supported?
The R7F100GAJ2DSP#AA0 provides up to 6 UARTA channels (with LIN support), 8 simplified SPI (CSI) channels, and 10 I²C/Simplified I²C channels. On the 32-pin HWQFN package, it supports at minimum 3 UARTA, 3 CSI, and 4 I²C interfaces-enabling concurrent connections to BLE modules, environmental sensors, and display drivers without software bit-banging.
What is the purpose and capability of the SNOOZE mode sequencer (SMS) in the R7F100GAJ2DSP#AA0?
The SNOOZE mode sequencer (SMS) in the R7F100GAJ2DSP#AA0 executes up to 32 preloaded commands-including ADC sampling, comparator evaluation, register arithmetic, and conditional branching-without waking the CPU, flash, or RAM. This enables µA-level periodic sensor polling and autonomous decision-making, reducing average system current by >;95% in duty-cycled applications.
Can the R7F100GAJ2DSP#AA0 perform background data flash rewriting while executing application code from program flash?
Yes, the R7F100GAJ2DSP#AA0 supports Background Operation (BGO) for its 8 KB data flash memory. Instructions can be fetched and executed from code flash while data flash is being rewritten-enabling seamless firmware parameter updates, logging, or OTA configuration changes without halting real-time operation or requiring dual-bank flash architecture.
