Product details
Overview
R7F100GPK3CFB#AA0 from Renesas is a 100-pin LFQFP, 5.0-V tolerant RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V at -40 to +105°C. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and SNOOZE mode sequencer for ultra-low-power sensor interface and industrial control applications.
For engineers reviewing the R7F100GPK3CFB#AA0 datasheet, R7F100GPK3CFB#AA0 pinout, R7F100GPK3CFB#AA0 application, or R7F100GPK3CFB#AA0 equivalent, key selection criteria include its 100-pin LFQFP-0.5mm package, industrial temperature grade (C), 256-KB flash/24-KB RAM configuration, integrated CTSU2L for up to 64-key mutual-capacitance touch, and support for background data flash rewriting via BGO.
Technical Context
The RL78/G23 core implements a 3-stage pipeline CISC architecture with configurable instruction timing (0.03125 µs min @ 32 MHz high-speed oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports multiply/divide/MAC instructions and 1-MB address space, enabling deterministic real-time control in resource-constrained environments.
Power management includes HALT, STOP, and SNOOZE modes - with 210-nA data retention current for 4 KB RAM and 41-µA/MHz active current. The SNOOZE mode sequencer executes up to 32 preconfigured commands (e.g., ADC sampling, comparison, GPIO toggle) without CPU, flash, or RAM activation, reducing system-level power in periodic sensing tasks.

FAQ
What is the maximum operating frequency and voltage range supported by the R7F100GPK3CFB#AA0?
The R7F100GPK3CFB#AA0 operates at up to 32 MHz using its high-speed on-chip oscillator and supports a wide supply voltage range of 1.6 V to 5.5 V. This allows direct interfacing with legacy 5-V systems and modern 1.8-V/3.3-V peripherals without external level shifters, and maintains full functionality across industrial temperature ranges (–40 to +105°C).
Does the R7F100GPK3CFB#AA0 include hardware support for capacitive touch sensing?
Yes, the R7F100GPK3CFB#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2), supporting both self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) operation at VDD = 1.8–5.5 V. It includes built-in noise cancellation and automatic calibration, eliminating the need for external touch controller ICs in HMI designs.
How does the SNOOZE mode sequencer in the R7F100GPK3CFB#AA0 reduce system power consumption?
The SNOOZE mode sequencer in the R7F100GPK3CFB#AA0 executes up to 32 preprogrammed commands - such as ADC sampling, value comparison, and GPIO toggling - autonomously without waking the CPU, flash, or RAM. This enables ultra-low-power periodic sensing (e.g., every 100 ms) with average current draw under 2 µA, significantly extending battery life in remote sensor applications.
Can the R7F100GPK3CFB#AA0 perform background data flash writes during program execution?
Yes, the R7F100GPK3CFB#AA0 supports Background Operation (BGO) for data flash, allowing instruction execution from code flash while simultaneously rewriting the 8 KB data flash memory. This enables seamless firmware updates, parameter logging, or secure key storage without interrupting real-time tasks - with guaranteed 1,000,000 rewrite cycles (typical).
What communication interfaces are available on the R7F100GPK3CFB#AA0 for industrial connectivity?
The R7F100GPK3CFB#AA0 provides up to 6 UARTA channels (LIN-bus compatible), 10 I²C/Simplified I²C channels, and 8 simplified SPI (CSI) channels. These interfaces support daisy-chain sensor networks, isolated RS-485 gateways (via UART-to-485 transceivers), and I²C-connected environmental sensors - all configurable via peripheral I/O redirection registers without PCB changes.
