Product details
Overview
R7F100GBF3CNP#AA0 from Renesas is a 32-pin, industrial-grade RL78/G23 16-bit MCU with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 16-bit TAU timers, RTC, 12-bit ADC (up to 26 channels), and dual DAC outputs - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GBF3CNP#AA0 datasheet, R7F100GBF3CNP#AA0 pinout, R7F100GBF3CNP#AA0 application, or R7F100GBF3CNP#AA0 equivalent, key selection criteria include its HWQFN-32 package with 0.5-mm pitch, -40°C to +105°C industrial temperature rating, SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GBF3CNP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 preconfigured operations using 21 command types - enabling periodic analog sensing, threshold comparison, and wake-up triggering while keeping CPU, flash, and RAM powered down.
Peripheral integration includes a Logic and Event Link Controller (ELCL) that routes event signals between peripherals (e.g., ADC completion → timer start → UART transmit), plus a Data Transfer Controller (DTC) supporting block, repeat, and chain transfers triggered by interrupts - reducing CPU load during high-throughput data movement across UART, SPI, and I²C interfaces.

Yes, the R7F100GBF3CNP#AA0 integrates the CTSU2L (Capacitive Touch Sensing Unit Level 2) which performs self-capacitance (up to 32 keys) and mutual-capacitance (8×8 matrix, up to 64 keys) sensing in hardware. It includes automatic drift compensation, noise rejection, and direct electrode connection via dedicated TSxx and TSCAP pins - eliminating need for external touch controller ICs.
Can the R7F100GBF3CNP#AA0 perform flash memory writes while executing code from flash?
Yes, the R7F100GBF3CNP#AA0 supports Background Operation (BGO) for data flash memory.
