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