NCF2960EHN/T0B04AJ

The NCF2960 is a second-generation Combo-key solution that combines a transponder, a microcontroller, and a radio transmitter in a tiny (4 x 4 mm) footprint. The basic transponder operation is compatible with security transponder families, including HT3, HT-AES, and HT-Pro2. Custom transponder functions can be implemented using the ROM library of the device by the application. The transponder circuitry is powered from the LF field and does not require a device battery supply. As a result, full operation is possible even when the battery is low. The RISC controller uses third-generation Micro RISC Kernel (MRK III), a low-power implementation that features a 16-bit architecture and executes instructions in a single machine clock cycle.
