Product details
Overview
R7F101GFE2DFP#AA1 from Renesas is a 44-pin LQFP-44, 128 KB flash, 12 KB RAM RL78/G24 microcontroller with 48-MHz CPU, 50-µA/MHz ultra-low-power operation, integrated DALI-2 and PMBus/SMBus interfaces, and hardware-based Flexible Application Accelerator (FAA) for motor control and digital power supply applications.
For engineers reviewing the R7F101GFE2DFP#AA1 datasheet, R7F101GFE2DFP#AA1 pinout, R7F101GFE2DFP#AA1 application, or R7F101GFE2DFP#AA1 equivalent, this MCU delivers deterministic real-time control with dual 16-bit timer KB30/KB31 for PFC, 12-bit ADC with simultaneous sampling, and on-chip code/data RAM for FAA co-processing - critical for lighting ballasts, industrial SMPS, and DALI-compliant LED drivers.
Technical Context
The R7F101GFE2DFP#AA1 integrates an RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution from 0.02083 µs (48 MHz) to 30.5 µs (32.768 kHz), plus a dedicated FAA core for 32-bit signed multiply-accumulate operations with 33-bit internal precision and shared 32-byte memory for CPU–FAA data exchange.
It features a configurable peripheral set including two UART/LIN interfaces, six I²C/Simplified I²C channels, one DALI interface, one PMBus-capable I²C (SM/PM bus), four comparators with selectable D/A or external reference, and KB30/KB31 complementary-output timers with 651-ps average PWM resolution at 96 MHz for high-fidelity power stage control.
