Product details
Overview
R7F101GGG3CNP#AA1 from Renesas is a 48-MHz RL78/G24 16-bit microcontroller with 128 KB code flash, 12 KB RAM, and integrated flexible application accelerator (FAA) for motor control and digital power. It features 48-pin HWQFN package, 1.6–5.5 V operation, –40 to +105°C industrial temperature range, and supports DALI-2, PMBus/SMBus, and multiple analog peripherals including 12-bit ADC with 23 channels.
For engineers reviewing the R7F101GGG3CNP#AA1 datasheet, R7F101GGG3CNP#AA1 pinout, R7F101GGG3CNP#AA1 application, or R7F101GGG3CNP#AA1 equivalent, this MCU delivers deterministic low-latency control in space-constrained industrial lighting, smart power supplies, and embedded motor drives where ultra-low active current (50 µA/MHz) and fast STOP-mode wakeup are critical.
Technical Context
The RL78 CPU core implements a CISC architecture with 3-stage pipeline and configurable instruction timing-0.02083 µs min execution at 48 MHz, or 30.5 µs at 32.768 kHz subsystem clock. It integrates a dedicated FAA core supporting 32-bit signed multiply/accumulate, limit operations, and 32-byte shared memory with the main CPU for real-time signal processing.
Peripherals include four 16-bit timer units (TAU, RD2, RG2, RJ), a 32-bit interval timer, RTC with alarm/correction, four comparators, programmable gain amplifier, dual DACs, and up to six I²C/Simplified I²C interfaces-configured via peripheral I/O redirection registers (PIORx) for flexible pin assignment without hardware redesign.
