IMP16C552

Description

Asynchronous Receiver and Transmitter

(UART) plus a bi-directional parallel data port

which fully support a Centronics compatible

printer interface

The low power COMS IMP16C522 is a single

device solution for serving two serial

input/output ports simultaneously and one fully

bi-directional parallel port for the IBM PC ATM

PS/2 and compatible systems. The parallel

port is full compatible to the Centronics printer

port and IBM serial parallel Adapter. Each

The two serial input/output Universal

Asynchronous Receiver/Transmitter interface

simultaneously

microprocessor-based

Universal Asynchronous

Receiver and

system. Each UART performs parallel-to-serial

conversion on the output and serial-to parallel

conversion on the input. Two modes of

operation exits for each I/0 channel after

a hardware reset. Each UART is functionally

transmitter (UART) is fully programmable.

Each UART in the IMP16C522 is capable of

buffering up to 16 bytes of data upon reception,

relieving the CPU of interrupt overhead.

Buffering of data also allows greater latency

time in interrupt servicing which is vital

in a multitasking environment, DMA signaling

between the internal FIFO buffers and host

CPU allows single or multiple character

transfers. Each UART has a maximum

recommended data rate of 256k with a clock

frequency of 80MHZ

compatible

the

IMP16C450(character

mode)and an alternate mode (FIFO

mode)which is only available on the IMP16C552

It can be activated through software relieving

the CPU of excessive overhead due to due to

interrupts. The complete status of each UART

can be read at any time from internal

registers. The parallel port allows information

received from the data base to be printed. The

parallel port together with the two serial ports,

provides IBM PC ATM and PS/2tm compatible

with a single device solution.

The IMP16C552 is an enhanced dual channel
