Product details
Overview
R7F101GLG2DFA#AA1 from Renesas is a 64-pin LQFP, 128 KB flash, 12 KB RAM RL78/G24 microcontroller with 48-MHz CPU, 50-µA/MHz ultra-low-power operation, integrated FAA accelerator, and dual DALI-2/I²C interfaces - deployed in digital lighting control systems requiring precise dimming, thermal management, and PMBus-compliant power monitoring.
For engineers reviewing the R7F101GLG2DFA#AA1 datasheet, R7F101GLG2DFA#AA1 pinout, R7F101GLG2DFA#AA1 application, or R7F101GLG2DFA#AA1 equivalent, key selection criteria include its 64-pin LQFP-0.65mm package, –40°C to +85°C consumer-grade temperature range, 12-bit ADC with 23 channels, and hardware DALI-2 transceiver supporting bidirectional addressable lighting commands without external level-shifting.
Technical Context
The R7F101GLG2DFA#AA1 integrates an RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 0.02083 µs minimum instruction execution at 48 MHz using PLL clocking. Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed multiply/accumulate and limit operations for real-time motor and lighting control loops.
It features a dual-domain timer system: four 16-bit TAU channels plus six specialized KB30–KB32 complementary PWM timers with 651-ps average resolution and dithering support, alongside a single-channel RTC with alarm and correction - all synchronized via Event Link Controller (ELC) for deterministic peripheral triggering without CPU overhead.
