CDP1854A,

CDP1854AC

Programmable Universal Asynchronous

Receiver/Transmitter (UART)

March 1997

Features

Description

• Two Operating Modes

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.

- Mode 0 - Functionally Compatible with Industry

Types Such as the TR1602A and CDP6402

- Mode 1 - Interfaces Directly with CDP1800-Series

Microprocessors without Additional Components

• Full or Half Duplex Operation

• Parity, Framing and Overrun Error Detection

• Baud Rate

- DC to 200K Bits/s at V . . . . . . . . . . . . . . . . . . . . 5V

- DC to 400K Bits/s at V . . . . . . . . . . . . . . . . . . . .10V

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.

• Fully Programmable with Externally Selectable Word

Length (5-8 Bits), Parity Inhibit, Even/Odd Parity, and

1, 1-1/2, or 2 Stop Bits

• False Start Bit Detection

Ordering Information

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.
