TL16C750
ASYNCHRONOUS COMMUNICATIONS ELEMENT
WITH 64-BYTE FIFOs AND AUTOFLOW CONTROL
SLLS191C – JANUARY 1995 – REVISED DECEMBER 1997
description (continued)
The TL16C750 ACE includes a programmable baud rate generator capable of dividing a reference clock by
divisors from 1 to (2¹⁶ – 1) and producing a 16 × reference clock for the internal transmitter logic. Provisions are
also included to use this 16 × clock for the receiver logic. The ACE accommodates a 1-Mbaud serial rate
(16-MHz input clock) so a bit time is 1 µs and a typical character time is 10 µs (start bit, 8 data bits, stop bit).
Two of the TL16C450 terminal functions have been changed to TXRDY and RXRDY, which provide signaling
to a direct memory access (DMA) controller.
