Overview
R7F101GBG3CFP#AA1 from Renesas is a 32-pin LQFP-packaged RL78/G24 16-bit microcontroller featuring 128 KB code flash, 12 KB RAM, and 4 KB data flash, operating at up to 48 MHz with 50 µA/MHz ultra-low-power efficiency. It integrates FAA for motor control acceleration, dual 12-bit ADCs with simultaneous sampling, DALI-2 interface, and 16-bit timers KB30–KB32 for PFC and multi-phase power conversion in lighting and digital power supplies.
For engineers reviewing the R7F101GBG3CFP#AA1 datasheet, R7F101GBG3CFP#AA1 pinout, R7F101GBG3CFP#AA1 application, or R7F101GBG3CFP#AA1 equivalent, key selection criteria include its –40°C to +105°C industrial temperature grade, 32-pin LQFP (7 × 7 mm, 0.80-mm pitch) package, integrated DALI-2 transceiver support, and hardware-based flexible application accelerator for real-time motor and power control loops.
Technical Context
The RL78/G24 core combines a 3-stage pipeline CISC architecture with configurable instruction timing (0.02083 µs min @ 48 MHz / 30.5 µs @ 32.768 kHz), supporting multiply/divide/accumulate operations and 1 Mbyte address space. Its FAA core delivers dedicated 32-bit signed arithmetic with 33-bit internal precision, limit operations, and 32-byte shared memory with the CPU for deterministic control loop handoff.
Peripheral integration includes six I²C/Simplified I²C interfaces, two UART/LIN channels, up to six CSI (SPI-compatible) units, one DALI interface, one PMBus/SMbus-capable I²C port, and KB-series timers with 651-ps average PWM resolution via dithering-enabling high-fidelity digital power supply regulation and DALI-compliant smart lighting control without external co-processors.
