ASYNCHRONOUS COMMUNICATIONS ELEMENT
SLLS136B – JANUARY 1994 – REVISED AUGUST 1996
description (continued)
The TL16C550B and the TL16C550BI ACE include programmable, on-board, baud rate generators. These
generators are capable of dividing a reference clock input by divisors from 1 to (2¹⁶ – 1) and producing a 16 ×
clock for driving the internal transmitter logic. Provisions are included to use this 16× clock to drive the receiver
logic. Also included in the ACE is a complete modem control capability and a processor interrupt system that
may be software tailored to user requirements to minimize the computing required to handle the
communications link.
The TL16C550B is available in a 40-pin DIP (N) package, 44-pin PLCC (FN) package, and 48-pin TQFP (PT)
package. The TL16C550BI is available in a 44-pin PLCC (FN) package.
