 TL16C550CFN  -ASYNCHRONOUS COMMUNICATIONS ELEMENT WITH AUTOFLOW CONTROL

 

description

The TL16C550C and the TL16C550CI are functional upgrades of the TL16C550B asynchronous

communications element (ACE), which in turn is a functional upgrade of the TL16C450. Functionally equivalent

to the TL16C450 on power up (character or TL16C450 mode), the TL16C550C and the TL16C550CI, like the

TL16C550B, can be placed in an alternate FIFO mode. This relieves the CPU of excessive software overhead

by buffering received and transmitted characters. The receiver and transmitter FIFOs store up to 16 bytes

including three additional bits of error status per byte for the receiver FIFO. In the FIFO mode, there is a

selectable autoflow control feature that can significantly reduce software overload and increase system

efficiency by automatically controlling serial data flow using RTS output and CTS input signals.

The TL16C550C and TL16C550CI perform serial-to-parallel conversions on data received from a peripheral

device or modem and parallel-to-serial conversion on data received from its CPU. The CPU can read the ACE

status at any time. The ACE includes complete modem control capability and a processor interrupt system that

can be tailored to minimize software management of the communications link.

Both the TL16C550C and the TL16C550CI ACE include a programmable baud rate generator capable of

dividing a reference clock by divisors from 1 to 65535 and producing a 16× reference clock for the internal

transmitter logic. Provisions are included to use this 16× clock for the receiver logic. The ACE accommodates

a 1-Mbaud serial rate (16-MHz input clock) so that 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 on the TL16C550C and the TL16C550CI have been changed to

TXRDY and RXRDY, which provide signaling to a DMA controller.
