It supports DALI-2, PMBus/SMBus, and operates from 1.6 to 5.5 V across –40 to +105°C industrial temperature range.
For engineers reviewing the R7F101G6G3CSP#CA1 datasheet, R7F101G6G3CSP#CA1 pinout, R7F101G6G3CSP#CA1 application, or R7F101G6G3CSP#CA1 equivalent, key selection criteria include its 20-pin LSSOP-20 package, 128 KB flash/12 KB RAM configuration, integrated DALI-2 interface, FAA-based real-time motor control acceleration, and industrial-grade thermal rating (–40 to +105°C).
Technical Context
The R7F101G6G3CSP#CA1 implements a CISC-based RL78 CPU with 3-stage pipeline and configurable instruction timing (0.02083 µs min at 48 MHz), paired with a dedicated Flexible Application Accelerator (FAA) supporting 32-bit signed multiply-accumulate and limit operations. Its on-chip resources include dual 32-bit timers KB30/KB31 for PFC control and 651-ps PWM resolution at 96 MHz with dithering.
It integrates four analog comparators, 12-channel 12-bit ADC with simultaneous sampling, two 10-bit DACs, programmable gain amplifier, and hardware event linking (ELC) enabling deterministic peripheral coordination without CPU intervention-critical for closed-loop motor and lighting control systems.

FAQ
What is the maximum operating frequency and power consumption of the R7F101G6G3CSP#CA1?
The R7F101G6G3CSP#CA1 operates at up to 48 MHz with a minimum instruction execution time of 0.02083 µs. Its active current consumption is specified at 50 µA/MHz, resulting in ~2.4 mA typical at full speed. In STOP mode, current drops to sub-µA levels with fast wake-up capability-enabling energy-efficient operation in battery-backed or thermally constrained applications.
Does the R7F101G6G3CSP#CA1 support DALI-2 communication natively?
Yes, the R7F101G6G3CSP#CA1 includes a dedicated digital addressable lighting interface (DALI) peripheral compliant with DALI-2 standards. It supports both DALI master and slave functionality in hardware, including frame generation, collision detection, and timing control-reducing firmware burden and ensuring protocol compliance without external transceivers.
What are the memory resources available on the R7F101G6G3CSP#CA1?
The R7F101G6G3CSP#CA1 integrates 128 KB of on-chip code flash memory (organized in 2 KB blocks), 4 KB of data flash memory rated for 1,000,000 write/erase cycles, and 12 KB of general-purpose SRAM. The code flash supports security features including block erase/write prohibition and boot swapping for safe firmware updates.
How does the Flexible Application Accelerator (FAA) enhance motor control performance in the R7F101G6G3CSP#CA1?
The FAA in the R7F101G6G3CSP#CA1 executes 32-bit signed multiply-accumulate and limit operations in hardware, offloading computationally intensive tasks like Clarke/Park transforms and PI current regulation from the main RL78 CPU. This enables deterministic, sub-microsecond loop execution-critical for high-speed BLDC and PMSM motor control without jitter or CPU saturation.
What package type and pin count does the R7F101G6G3CSP#CA1 use?
The R7F101G6G3CSP#CA1 uses a 20-pin plastic LSSOP package (4.4 × 6.5 mm, 0.65-mm pitch) with lead-free, RoHS-compliant construction. The #CA1 suffix indicates magazine packaging-optimized for automated SMT placement in high-volume manufacturing of compact lighting and power modules.
