Product details
Overview
R7F100GPK2DFA#AA0 from Renesas is a 100-pin, 256-KB code flash, 24-KB RAM RL78/G23 16-bit microcontroller operating at 1.6–5.5 V, featuring ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual 16-bit timer arrays for motor control and sensor interfacing in battery-powered industrial HMI systems.
For engineers reviewing the R7F100GPK2DFA#AA0 datasheet, R7F100GPK2DFA#AA0 pinout, R7F100GPK2DFA#AA0 application, or R7F100GPK2DFA#AA0 equivalent, this page delivers verified electrical specifications, validated LFQFP-100 package mapping, confirmed SNOOZE mode sequencer operation, and real-world design guidance for low-power embedded control with integrated analog peripherals.
Technical Context
The R7F100GPK2DFA#AA0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a dedicated SNOOZE mode sequencer (SMS) supporting up to 32 sequential low-power operations without CPU wake-up, enabling autonomous sensor polling and event-driven state transitions.
Peripheral integration includes a 10-channel I²C/Simplified I²C interface, 6-channel UARTA with LIN support, 8-channel 16-bit TAU, 12-bit A/D converter with 26 input channels and internal 1.48-V reference, and a 2-channel 8-bit D/A converter with real-time output capability - all accessible via multiplexed I/O on the 100-pin LFQFP package.

The R7F100GPK2DFA#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator, supported across the full 1.6–5.5 V VDD range. At 32 MHz, minimum instruction execution time is 0.03125 µs. The device also supports ultra-low-speed operation at 32.768 kHz for sub-microamp RTC and standby functions, maintaining full functionality down to 1.6 V.
Does the R7F100GPK2DFA#AA0 support hardware-based capacitive touch sensing, and how many keys can it handle?
Yes, the R7F100GPK2DFA#AA0 integrates the CTSU2L capacitive touch sensing unit. It supports up to 32 keys in self-capacitance mode (one pin per key) or up to 64 keys in mutual-capacitance matrix mode (8 × 8 configuration), with built-in noise cancellation and auto-calibration-no external touch controller IC is required for either topology.
How does the SNOOZE mode sequencer (SMS) function in the R7F100GPK2DFA#AA0, and what tasks can it perform autonomously?
The SNOOZE mode sequencer (SMS) in the R7F100GPK2DFA#AA0 executes up to 32 predefined commands-including ADC conversions, value comparisons, GPIO toggles, and register writes-without CPU, flash, or RAM activation. It operates independently using only the subsystem clock, enabling ultra-low-power periodic sensor polling, threshold monitoring, and state transitions in battery-critical applications.
What are the data flash endurance and background operation capabilities of the R7F100GPK2DFA#AA0?
The R7F100GPK2DFA#AA0 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical). It supports Background Operation (BGO), allowing full program execution from code flash memory while simultaneously rewriting data flash-enabling seamless firmware updates, parameter logging, and configuration storage without system interruption.
Which communication interfaces are available on the R7F100GPK2DFA#AA0, and are they pin-multiplexed?
The R7F100GPK2DFA#AA0 offers 10-channel I²C/Simplified I²C, 6-channel UARTA (with LIN-bus support), 8-channel Simplified SPI (CSI), and 1-channel remote control signal receiver. All interfaces are fully pin-multiplexed on the 100-pin LFQFP package; specific pin assignments (e.g., P60/P61 for I²C, P10–P12 for SPI) are configured via peripheral I/O redirection registers (PIOR) in software.
