Overview
R7F100GGN2DFB#AA0 from Renesas is a 48-pin LFQFP-packaged RL78/G23 16-bit microcontroller with 256 KB code flash, 8 KB data flash, and 24 KB RAM, operating from 1.6–5.5 V, featuring ultra-low-power STOP mode (210 nA RAM retention), capacitive touch sensing (CTSU2L), and integrated RTC, UARTA, IICA, and SAU peripherals for industrial HMI and sensor node applications.
For engineers reviewing the R7F100GGN2DFB#AA0 datasheet, R7F100GGN2DFB#AA0 pinout, R7F100GGN2DFB#AA0 application, or R7F100GGN2DFB#AA0 equivalent, this page delivers verified electrical specs, package mapping, functional role in low-power embedded systems, and validated alternative options for design-in and supply continuity.
Technical Context
The R7F100GGN2DFB#AA0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a SNOOZE mode sequencer (SMS) enabling autonomous low-power peripheral sequencing without CPU wake-up.
Its peripheral set includes a 12-bit A/D converter (26 channels), dual 8-bit D/A outputs, two comparators with selectable internal/external reference, and an Event Link Controller (ELCL) for hardware-triggered signal routing between timers, ADC, and communication interfaces-enabling deterministic real-time response in resource-constrained designs.
Key Specifications
