Product details
Overview
R7F100GEH2DNP#HA0 from Renesas is a 40-pin RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating at 1.6–5.5 V. It integrates capacitive touch sensing (CTSU2L), 12-bit ADC (26 channels), dual 8-bit DACs, RTC, and ultra-low-power STOP mode (210 nA data retention). Used in battery-powered consumer HMI devices requiring reliable touch control and mixed-signal processing.
For engineers reviewing the R7F100GEH2DNP#HA0 datasheet, R7F100GEH2DNP#HA0 pinout, R7F100GEH2DNP#HA0 application, or R7F100GEH2DNP#HA0 equivalent, key selection criteria include its HWQFN-40 package, consumer-grade temperature range (−40 to +85°C), integrated CTSU2L for up to 64-key mutual-capacitance touch, and support for background data flash rewriting during program execution.
Technical Context
The R7F100GEH2DNP#HA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer enables autonomous low-power sensor polling without CPU wake-up, using 21 configurable commands across 32 sequential steps.
Peripheral integration includes ELCL for event-driven logic routing between functions (e.g., ADC trigger → DMA transfer), DTC for interrupt-activated data transfers with chain capability, and multiple serial interfaces: up to 10 I²C/Simplified I²C channels, 6 UART/UARTA (LIN-capable), and 8 CSI/SPI channels - all configurable via peripheral I/O redirection register (PIOR).
