.. NS16C2552/NS16C2752 Dual UART with 16-byte/64-byte FIFO’s and up to 5 Mbit/s Data Rate PRELIMINARY August 2006 NS16C2552/NS16C2752 Dual UART with 16-byte/64-byte FIFO’s and up to 5 Mbit/s Data Rate 1.0 General Description The NS16C2552 and NS16C2752 are dual channel Universal Asynchronous Receiver/Transmitter (DUART). The footprint and the functions are patible to the PC16552D, while new Features are added to the UART device. These Features include low voltage support, 5V tolerant inputs, enhanced Features , enhanced register set, and higher data rate. The two serial channels are pletely independent of each other, except for a mon CPU interface and crystal...
