NXP remote keyless entry transponder combo IC NCF2960 Compact, single-chip solution for remote keyless entry Delivering rugged performance in a very small (4 x 4 mm) footprint, this highly integrated solution maximizes design freedom and is ideal for advanced Combo-Key applications. Special features of` the integrated RF transmitter support frequency hopping and ensure reliable operation even in` RF-jammed environments. Key features `` Single-chip security transponder and keyless entry solution `` 16-bit Harvard architecture `` On-chip UHF transmitter (315 / 434 / 868 / 915 MHz band) `` Transponder emulation based on HT3, HT-AES, or HT-Pro 2 `` Calculation unit supporting HT3 (96-bit) and AES (128-bit) `` 16 KB user EROM for application `` 2 KB ultra-low-power EEPROM `` 1 KB RAM `` Up to eight command buttons with wake-up function `` I/O with current source for direct LED drive `` Stabilized RF output power `` Temperature sensor `` Single lithium cell operation (2.1 to 3.6 V) `` C-compiler supported software development `` HVQFN24 (4 x 4 mm) with wettable flanks Applications `` Combo-Key applications that combine remote keyless entry with vehicle immobilization The NXP 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 NXP’s 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 NXP’s 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. The on-chip UHF transmitter requires only a single 27.6  MHz reference crystal and loop antenna matching circuitry to operate in one of the following bandwidths: 315 / 434 / 868 / 915 MHz bands. The RF multi-channel capability enables frequency hopping and ensures reliable operation in RF-jammed environments. There are up to eight I/O ports, with one designed for use with a dedicated LED driver port, and up to eight inputs for command buttons. There is a temperature sensor for battery management and an on-chip pseudo-random number (PRN) generator for use with security protocols. A fractional-N PLL allows compensation for initial XTL tolerance. The device includes 2 KB of ultra-low-power serial EEPROM memory (with access control defined by the application), 1 KB ` of RAM, and up to 16 KB of Flash-like EROM for the application code. The keyless entry code can be generated by the built-in, hardwired calculation unit or by a software-based algorithm. The device is housed in a tiny 24-pin HVQVN package that consumes only 16 mm2 of board space, so it enables ultracompact designs with maximum freedom for key styling. Wettable package flanks allow optical soldering inspection without an x-ray. The Flash-like EROM of the device supports in-circuitry programming and debugging of the application code.
