Product details
Overview
R7F101GFE3CFP#AA1 from Renesas is a 44-pin LQFP-packaged RL78/G24 16-bit microcontroller featuring 128 KB code flash, 4 KB data flash, and 12 KB RAM, operating at up to 48 MHz with 50-µA/MHz ultra-low-power efficiency. It integrates FAA for motor control acceleration, dual DACs, 23-channel 12-bit ADC, four comparators, and dedicated DALI-2 and PMBus/SMBus interfaces for digital lighting and power supply applications.
For engineers reviewing the R7F101GFE3CFP#AA1 datasheet, R7F101GFE3CFP#AA1 pinout, R7F101GFE3CFP#AA1 application, or R7F101GFE3CFP#AA1 equivalent, key selection factors include its 44-pin LQFP-0.8mm package, –40°C to +105°C industrial temperature grade, integrated DALI-2 transceiver capability, and hardware-accelerated PWM timing for PFC and multi-phase motor control.
Technical Context
The RL78/G24 core combines CISC architecture with a 3-stage pipeline and configurable instruction timing (0.02083 µs min @ 48 MHz or 30.5 µs @ 32.768 kHz), enabling dynamic trade-offs between performance and power. Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed arithmetic, limit operations, and shared 32-byte memory with the CPU for real-time motor loop execution.
Peripheral integration includes six I²C/Simplified I²C channels, three UART/LIN interfaces, two to six CSIs (SPI-compatible), one DALI interface, and timer RD2 with 651-ps average PWM resolution via dithering-enabling precise digital power control without external signal conditioning.
