CDP1854A,

CDP1854AC

Programmable Universal Asynchronous

Receiver/Transmitter (UART)

Description

The CDP1854A and CDP1854AC are silicon-gate CMOS

Universal Asynchronous Receiver/Transmitter (UART) cir-

cuits. They are designed to provide the necessary formatting

and control for interfacing between serial and parallel data.

For example, these UARTs can be used to interface between

a peripheral or terminal with serial I/O ports and the 8-bit

CDP1800-series microprocessor parallel data bus system.

The CDP1854A is capable of full duplex operation, i.e.,

simultaneous conversion of serial input data to parallel out-

put data and parallel input data to serial output data.

The CDP1854A UART can be programmed to operate in

one of two modes by using the mode control input. When the

input is high (MODE = 1), the CDP1854A is directly compati-

ble with the CDP1800-series microprocessor system without

additional interface circuitry. When the mode input is low

(MODE = 0), the device is functionally compatible with indus-

try standard UART’s such as the TR1602A and CDP6402. It

is also pin compatible with these types, except that pin 2 is

used for the mode control input.

The CDP1854A and the CDP1854AC are functionally identi-

cal. The CDP1854A has a recommended operating voltage

range of 4V to 10.5V, and the CDP1854AC has a recom-

mended operating voltage range of 4V to 6.5V.
