Product details
Overview
R7F100GSK2DFB#BA0 from Renesas is an RL78/G23 128-pin, 5.5-V, ultra-low-power 16-bit MCU with 256 KB code flash, 8 KB data flash, and 24 KB RAM, featuring capacitive touch sensing, 16-bit timers, 12-bit ADC, and dual DACs - deployed in industrial HMI control panels requiring extended battery life and robust noise immunity.
For engineers reviewing the R7F100GSK2DFB#BA0 datasheet, R7F100GSK2DFB#BA0 pinout, R7F100GSK2DFB#BA0 application, or R7F100GSK2DFB#BA0 equivalent, key selection criteria include STOP-mode wakeup time (≤3.5 µs), CTSU2L self/mutual capacitance support (up to 64 keys), and integrated SNOOZE mode sequencer for autonomous sensor polling without CPU wake-up.
Technical Context
The R7F100GSK2DFB#BA0 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 integrates a dedicated SNOOZE mode sequencer (SMS) capable of executing 32 sequential commands across 21 instruction types - enabling low-power background processing of capacitive touch or timer events.
It features a Logic and Event Link Controller (ELCL) that routes signals between peripherals without CPU intervention, plus a Data Transfer Controller (DTC) supporting chain transfer and block/normal/repeat modes triggered by 128 interrupt sources - reducing firmware overhead in real-time sensor acquisition and communication stacks.
