TL16C450FN

UART интерфейс, 1 канал, 256 Кбит/с, 4.75 В, 5.25 В, LCC, 44 вывод(-ов).

The TL16C450FN is an Universal Asynchronous Receiver/Transmitter (UART) without FIFO. It is CMOS version of an asynchronous communications element (ACE). It typically functions in a microcomputer system as a serial input/output interface. It performs serial-to-parallel conversion on data received from a peripheral device or modem and parallel-to-serial conversion on data received from its CPU. The CPU can read and report on the status of the ACE at any point in the ACE's operation. Reported status information includes the type of transfer operation in progress, the status of the operation and any error conditions encountered. It includes a programmable, on-board, baud rate generator. This generator is capable of dividing a reference clock input by divisors from 1 to (2?? -1) and producing a 16x clock for driving the internal transmitter logic. Provisions are included to use this 16x clock to drive the receiver logic.
