Product details
Overview
R7F101GLG2DFB#AA1 from Renesas is a 64-pin LFQFP, 5.5-V, -40°C to +85°C industrial-grade RL78/G24 microcontroller featuring a 48-MHz RL78 CPU core, 128 KB code flash, 4 KB data flash, and 12 KB RAM-designed for digital power supplies, motor control, and DALI-2 lighting systems with integrated FAA accelerator and PMBus/SMBus support.
For engineers reviewing the R7F101GLG2DFB#AA1 datasheet, R7F101GLG2DFB#AA1 pinout, R7F101GLG2DFB#AA1 application, or R7F101GLG2DFB#AA1 equivalent, key selection criteria include its 64-pin LFQFP-0.50mm package, dual 12-bit ADC (23-channel), DALI-2 interface compliance, 32-bit interval timer, and 16-bit KB timers with 651-ps PWM resolution for PFC and multi-phase control.
Technical Context
The R7F101GLG2DFB#AA1 integrates a CISC-based RL78 CPU core with 3-stage pipeline and configurable instruction timing (0.02083 µs min @ 48 MHz), plus a dedicated Flexible Application Accelerator (FAA) core supporting 32-bit signed multiply/accumulate, limit operations, and shared 32-byte memory with the CPU. It operates across 1.6–5.5 V and supports ultra-low-power modes including STOP, SNOOZE, and HALT.
Peripheral integration includes six I²C/Simplified I²C interfaces, two UART/LIN channels, up to six CSI (SPI-compatible) units, one DALI-2 transceiver, one PMBus/SMBus-capable I²C port, four comparators with selectable reference sources, and three 16-bit KB timers optimized for power factor correction with dithering, forced output stop, and interleaved operation.
