FAQ

What is the maximum operating temperature rating for the R7F101G7G3CNP#AA1?

The R7F101G7G3CNP#AA1 is rated for industrial operation from −40°C to +105°C, as indicated by the "3C" suffix in its part number. This rating is validated across all specified electrical parameters including 48-MHz CPU operation, ADC accuracy, and DALI-2 timing compliance - making it suitable for enclosed LED drivers and power converters without forced cooling.

Does the R7F101G7G3CNP#AA1 include an integrated DALI-2 transceiver?

Yes, the R7F101G7G3CNP#AA1 integrates a fully compliant DALI-2 transceiver per IEC 62386-102, accessible via pins P00 (DALITxD0) and P01 (DALIRxD0). It requires no external transceiver IC or level-shifting components, and supports both master and slave modes with built-in bus voltage monitoring and short-circuit protection logic.

How many analog-to-digital converter channels does the R7F101G7G3CNP#AA1 support?

The R7F101G7G3CNP#AA1 features a 12-bit ADC with up to 19 analog input channels, including two dedicated sample-and-hold circuits for simultaneous sampling. These channels are distributed across pins P00–P01, P120, P147, P20–P23, and P10–P17 - enabling concurrent voltage and current measurement in digital power and motor control applications.

What is the role of the Flexible Application Accelerator (FAA) in the R7F101G7G3CNP#AA1?

The FAA in the R7F101G7G3CNP#AA1 is a dedicated hardware accelerator that performs 32-bit signed multiply-accumulate, addition/subtraction, and limit operations independently of the RL78 CPU. It offloads time-critical computations in PFC, lighting dimming, and motor control algorithms - reducing CPU load and enabling deterministic sub-microsecond loop execution without software overhead.

Can the R7F101G7G3CNP#AA1 operate from a 3.3-V supply while maintaining full 48-MHz performance?

Yes, the R7F101G7G3CNP#AA1 operates across a 1.6-V to 5.5-V supply range and maintains full 48-MHz CPU performance at 3.3 V. Its high-speed on-chip oscillator achieves ±1.0% accuracy from 1.8 V to 5.5 V and −20°C to +85°C, and the device's 50-µA/MHz active current ensures efficient operation in 3.3-V-powered LED drivers and industrial sensors.
