It supports DALI-2, PMBus/SMBus, and multiple analog peripherals including 12-bit ADC with 23 channels and dual 10-bit DACs, operating from 1.6 to 5.5 V across –40 to +85°C.
For engineers reviewing the R7F101GJG2DFA#AA1 datasheet, R7F101GJG2DFA#AA1 pinout, R7F101GJG2DFA#AA1 application, or R7F101GJG2DFA#AA1 equivalent, key selection criteria include its 52-pin LQFP package, consumer-grade temperature range (–40 to +85°C), 128 KB flash/12 KB RAM configuration, integrated DALI-2 interface, and FAA-based real-time motor control acceleration.
Technical Context
The R7F101GJG2DFA#AA1 implements a CISC-based RL78 CPU core with 3-stage pipeline and configurable instruction timing (0.02083 µs min at 48 MHz). Its Flexible Application Accelerator (FAA) provides dedicated 32-bit signed arithmetic, limit operations, and shared 32-byte memory with the CPU for deterministic motor control loops.
Peripheral integration includes six I²C/Simplified I²C interfaces, two UART/LIN channels, one DALI transceiver, four comparators with selectable reference sources, and KB30–KB32 complementary PWM timers supporting PFC control, dithering, and 651-ps average resolution at 96 MHz - all optimized for lighting and digital power supply systems.

FAQ
What is the maximum operating frequency of the R7F101GJG2DFA#AA1 CPU core?
The R7F101GJG2DFA#AA1 features an RL78 CPU core with a maximum operating frequency of 48 MHz, achieving a minimum instruction execution time of 0.02083 µs using the high-speed on-chip oscillator or PLL clock. This performance level is maintained across its full 1.6–5.5 V supply range and –40 to +85°C operating temperature.
Does the R7F101GJG2DFA#AA1 support DALI-2 communication natively?
Yes, the R7F101GJG2DFA#AA1 integrates a complete DALI-2 physical layer and protocol engine, including dedicated pins P00 (DALITxD0) and P01 (DALIRxD0). No external transceiver is required, and the MCU handles frame encoding, collision detection, and timing compliance per IEC 62386-102.
What are the memory resources available on the R7F101GJG2DFA#AA1?
The R7F101GJG2DFA#AA1 provides 128 KB of code flash memory (with 2 KB erase blocks and security lock), 4 KB of FAA code RAM, 2 KB of FAA data RAM, 12 KB of general-purpose RAM, and 4 KB of data flash memory supporting background operation and 1,000,000 write cycles.
How does the Flexible Application Accelerator (FAA) enhance motor control performance in the R7F101GJG2DFA#AA1?
The FAA in the R7F101GJG2DFA#AA1 executes 32-bit signed multiply, add, subtract, and limit operations independently of the CPU, with 32-byte shared memory for low-latency data exchange. This enables deterministic sub-1 µs current-loop execution in BLDC/PMSM drives, freeing the RL78 core for higher-level tasks like commutation sequencing and fault handling.
What package type and pin count does the R7F101GJG2DFA#AA1 use?
The R7F101GJG2DFA#AA1 uses a 52-pin plastic LQFP package with 10 × 10 mm body size and 0.65-mm lead pitch, designated by the "FA" suffix in the part number and shipped in trays (#AA1). It is pin-compatible with other RL78/G24 52-pin variants such as R7F101GJE2DFA#AA1.
