Product details
Overview
R7F100GBH2DNP#AA0 from Renesas is a 32-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 delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (CTSU2L), and supports UART, I²C, SPI, RTC, and 16-bit timers for embedded control in battery-powered consumer devices.
For engineers reviewing the R7F100GBH2DNP#AA0 datasheet, R7F100GBH2DNP#AA0 pinout, R7F100GBH2DNP#AA0 application, or R7F100GBH2DNP#AA0 equivalent, key selection criteria include its HWQFN-32 package, -40 to +85°C industrial-grade temperature range, 128 KB flash/16 KB RAM memory configuration, and CTSU2L-based touch interface capability for space-constrained, low-power HMI designs.
Technical Context
The R7F100GBH2DNP#AA0 implements the RL78 CPU core with a 3-stage pipeline, 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 peripheral sequencing without CPU wake-up, while the Logic and Event Link Controller (ELCL) allows configurable event-driven signal routing between peripherals.
It integrates a 12-bit A/D converter (up to 26 channels), dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and a hardware-capacitive sensing unit (CTSU2L) supporting up to 32 self-capacitance keys or 64 mutual-capacitance keys - all operating within the 1.8–5.5 V analog supply range.
