Product details
Overview
R7F100GFK2DFP#HA0 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 features ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), 12-bit A/D converter (26 channels), and dual UART/LIN interfaces - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GFK2DFP#HA0 datasheet, R7F100GFK2DFP#HA0 pinout, R7F100GFK2DFP#HA0 application, or R7F100GFK2DFP#HA0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +85°C consumer-grade temperature range, and support for SNOOZE mode sequencer-driven autonomous peripheral operation without CPU wake-up.
Technical Context
The R7F100GFK2DFP#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its SNOOZE mode sequencer (SMS) executes up to 32 preconfigured commands-including ADC sampling, comparator comparison, and timer counting-without CPU, RAM, or flash activation.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling hardware-triggered signal routing between functions like UART, timers, and CTSU, plus a Data Transfer Controller (DTC) supporting block, repeat, and chain transfers activated by interrupt sources - reducing firmware overhead in real-time sensor aggregation and control loops.
