It targets industrial sensor nodes and battery-powered HMI control.
For engineers reviewing the R7F100GEF3CNP#HA0 datasheet, R7F100GEF3CNP#HA0 pinout, R7F100GEF3CNP#HA0 application, or R7F100GEF3CNP#HA0 equivalent, key selection criteria include its 40-pin HWQFN package with exposed die pad, 128 KB flash/16 KB RAM memory configuration, C-grade industrial temperature range (−40 to +105°C), and integrated CTSU2L for up to 64-key mutual-capacitance touch panels.
Technical Context
The R7F100GEF3CNP#HA0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes SNOOZE mode sequencer (SMS) for autonomous low-power peripheral sequencing without CPU wake-up. Its power management integrates POR, dual LVDs, and HALT/STOP/SNOOZE modes.
Peripheral integration includes 8× 16-bit TAU channels, 1× 32-bit interval timer, 4× I²C/Simplified I²C channels, 3× UART/UARTA (LIN-capable), 3× Simplified SPI (CSI), 1× remote control receiver, and 2× 8-bit DAC outputs with real-time update capability - all accessible via multiplexed pins on the 40-pin HWQFN footprint.
