Product details
Overview
R7F100GGH2DNP#AA0 from Renesas is a 48-pin HWQFN-packaged RL78/G23 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 16 KB RAM, operating from 1.6–5.5 V. It delivers ultra-low power consumption (41 µA/MHz active, 210 nA data retention), integrated capacitive touch sensing (up to 64 keys), 12-bit ADC (26 channels), dual DAC, RTC, and multiple serial interfaces - deployed in battery-powered industrial HMI and sensor node applications.
For engineers reviewing the R7F100GGH2DNP#AA0 datasheet, R7F100GGH2DNP#AA0 pinout, R7F100GGH2DNP#AA0 application, or R7F100GGH2DNP#AA0 equivalent, key selection considerations include its 48-pin HWQFN-0.5 mm pitch package, consumer-grade temperature range (−40 to +85°C), SNOOZE mode sequencer for autonomous low-power sensing, and hardware ELCL for event-driven peripheral coordination without CPU intervention.
Technical Context
The R7F100GGH2DNP#AA0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). Its SNOOZE mode sequencer executes up to 32 preconfigured commands-including ADC sampling, comparison, and conditional branching-without waking the CPU, flash, or RAM.
Peripheral integration includes a Logic and Event Link Controller (ELCL) enabling direct signal routing between peripherals (e.g., timer output triggering ADC conversion), a capacitive sensing unit (CTSU2L) supporting both self- and mutual-capacitance methods, and background operation (BGO) for concurrent data flash rewriting and program execution.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7F100GGH3CFB#AA0 | Same core, memory, and peripherals; differs in package (48-pin LFQFP, 0.5 mm pitch) and temperature grade (−40 to +105°C industrial) | Required for extended temperature operation or PCB assembly compatibility with LFQFP footprint | Select when industrial ambient (−40 to +105°C) or through-hole reflow compatibility is mandatory |
| R7F100GGL2DNP#AA0 | Same 48-pin HWQFN package and consumer temp grade, but upgraded to 512 KB code flash and 48 KB RAM | Suitable for applications needing larger firmware image or real-time data buffering (e.g., OTA update staging) | Choose when future firmware expansion or complex protocol stacks (Modbus TCP, BLE host) demand headroom beyond 128 KB flash |
