Product details
Overview
R7F100GBF2DNP#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 true low-power performance (41 µA/MHz active, 210 nA data retention), integrates capacitive touch sensing (CTSU2L), RTC, 16-bit TAU timers, UARTA/IICA/SAU interfaces, and supports consumer-grade ambient operation (−40 to +85°C).
For engineers reviewing the R7F100GBF2DNP#AA0 datasheet, R7F100GBF2DNP#AA0 pinout, R7F100GBF2DNP#AA0 application, or R7F100GBF2DNP#AA0 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for battery-powered HMI, sensor node, and appliance control designs.
Technical Context
The RL78/G23 core implements a CISC architecture with 3-stage pipeline and configurable instruction timing - supporting ultra-low-speed execution (30.5 µs @ 32.768 kHz) and high-speed operation (0.03125 µs @ 32 MHz). Its SNOOZE mode sequencer enables autonomous peripheral sequencing without CPU wake-up, reducing power in intermittent sensing tasks.
Peripheral integration includes a 21-command SMS engine, ELCL event routing logic, 8–26-channel 12-bit ADC with internal reference and temperature sensor, dual 8-bit DAC outputs, two comparators with selectable reference sources, and hardware-accelerated capacitive touch (self- and mutual-capacitance modes up to 64 keys).
