Product details
Overview
R7F100GFK2DFP#AA0 from Renesas is a 44-pin LQFP-packaged 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. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and dual-clock domain operation supporting high-speed (32 MHz) and ultra-low-speed (32.768 kHz) modes for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R7F100GFK2DFP#AA0 datasheet, R7F100GFK2DFP#AA0 pinout, R7F100GFK2DFP#AA0 application, or R7F100GFK2DFP#AA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, 256 KB flash/24 KB RAM memory configuration, CTSU2L capacitive sensing support, SNOOZE mode sequencer for autonomous low-power event handling, and industrial-grade temperature range (−40 to +85°C).
Technical Context
The R7F100GFK2DFP#AA0 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, enabling configurable instruction execution time from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its dual-clock system integrates high-, middle-, and low-speed on-chip oscillators-32 MHz ±1.0% accuracy, 4/2/1 MHz adjustable, and 32.768 kHz adjustable-with independent power domains for STOP/HALT/SNOOZE modes.
Peripheral integration includes a 21-command SNOOZE mode sequencer (SMS) that executes autonomous sequences without CPU/RAM/flash activation, an Event Link Controller (ELCL) for hardware-triggered peripheral chaining, and a Logic and Event Link Controller enabling programmable signal routing between timers, ADC, UART, and CTSU2L-reducing software overhead in deterministic real-time systems.
