Product details
Overview
R7F100GAG2DSP#AA0 from Renesas is an RL78/G23 8-bit microcontroller with 96 KB code flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +85°C. It integrates a capacitive touch sensing unit (CTSU2L), 16-bit timer array (TAU) with up to 16 channels, 12-bit A/D converter (26-channel), and UART/I²C/SPI interfaces - deployed in battery-powered consumer HMI systems requiring ultra-low power operation.
For engineers reviewing the R7F100GAG2DSP#AA0 datasheet, R7F100GAG2DSP#AA0 pinout, R7F100GAG2DSP#AA0 application, or R7F100GAG2DSP#AA0 equivalent, key selection criteria include its 44-pin LQFP package, 26-channel 12-bit ADC, CTSU2L support for up to 64 keys, SNOOZE mode sequencer for autonomous low-power sensing, and integrated 32.768-kHz RTC with alarm and correction.
Technical Context
The R7F100GAG2DSP#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). Its SNOOZE mode sequencer (SMS) executes up to 32 sequential operations using 21 command types without CPU, flash, or RAM activation.
Peripheral integration includes Logic & Event Link Controller (ELCL) for configurable signal routing between peripherals, Data Transfer Controller (DTC) with chain transfer, and background operation (BGO) for concurrent code execution during data flash rewriting - enabling deterministic real-time response in resource-constrained embedded control.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time for the R7F100GAG2DSP#AA0?
The R7F100GAG2DSP#AA0 supports a maximum operating frequency of 32 MHz using the high-speed on-chip oscillator. At this speed, the minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz, where the minimum instruction time extends to 30.5 µs - enabling dynamic trade-offs between performance and power consumption based on real-time workload demands.
Does the R7F100GAG2DSP#AA0 support hardware-based capacitive touch sensing, and how many keys can it manage?
Yes, the R7F100GAG2DSP#AA0 integrates the CTSU2L capacitive sensing unit. It supports self-capacitance mode for up to 32 independent keys using single-pin configuration, or mutual capacitance mode in an 8×8 matrix for up to 64 keys. The unit includes built-in spread-spectrum modulation and automatic baseline tracking, ensuring reliable operation in electrically noisy environments without external components.
What are the power supply requirements and low-power modes supported by the R7F100GAG2DSP#AA0?
The R7F100GAG2DSP#AA0 operates from a single 1.6–5.5 V supply and supports HALT, STOP, and SNOOZE modes. In STOP mode with 4 KB RAM retention, current drops to 210 nA; full 12 KB RAM retention increases current to 320 nA. SNOOZE mode enables autonomous peripheral sequencing (e.g., ADC → compare → CTSU) without CPU activation, reducing average system power in periodic-sensing applications.
Can the R7F100GAG2DSP#AA0 perform concurrent code execution and data flash rewriting?
Yes, the R7F100GAG2DSP#AA0 supports Background Operation (BGO) for data flash memory. While rewriting the 8 KB data flash region, the CPU can continue executing instructions from code flash - enabling seamless firmware parameter updates or logging without interrupting real-time control tasks. This capability is confirmed in the R01DS0395EJ0140 datasheet Section 1.1 "Data flash memory".
What serial communication interfaces are integrated into the R7F100GAG2DSP#AA0, and how many channels does each support?
The R7F100GAG2DSP#AA0 integrates three serial interface types: UARTA (up to 6 channels), I²C/Simplified I²C (up to 10 channels), and Simplified SPI (CSINote¹, up to 8 channels). All are implemented in the Serial Array Unit (SAU) and Serial Interface (SCI) modules. Channel count allocation depends on pin multiplexing and peripheral I/O redirection register (PIOR) settings - detailed in Table 1-5 of the R01DS0395EJ0140 datasheet.
