Product details
Overview
R7F101GBG4CNP#AA1 from Renesas is a 32-pin HWQFN-packaged RL78/G24 16-bit microcontroller featuring 128 KB code flash, 4 KB data flash, 12 KB RAM, 48-MHz CPU operation, and integrated DALI-2 interface - designed for digital lighting control systems requiring precise timing, low-power operation, and certified communication compliance.
For engineers reviewing the R7F101GBG4CNP#AA1 datasheet, R7F101GBG4CNP#AA1 pinout, R7F101GBG4CNP#AA1 application, or R7F101GBG4CNP#AA1 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm, 0.50-mm pitch) package, –40 to +125°C industrial temperature grade (4C), 128 KB flash capacity, and native DALI-2 transceiver support without external level-shifting components.
Technical Context
The R7F101GBG4CNP#AA1 integrates an RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 0.02083 µs minimum instruction execution at 48 MHz, alongside a dedicated Flexible Application Accelerator (FAA) core for real-time motor and power control math operations including 32-bit signed multiply-accumulate with 33-bit internal precision.
It supports dual-clock domain operation: high-speed on-chip oscillator (±1.0% accuracy across 1.8–5.5 V, –20 to +85°C) and low-speed 32.768 kHz subsystem clock, enabling ultra-low-power STOP mode with fast wakeup and SNOOZE mode for background ADC/DAC operation while CPU sleeps.
