CDP1854A/3,  
CDP1854AC/3  
High Reliability CMOS Programmable Universal  
Asynchronous Receiver/Transmitter (UART)  
March 1997  
Features  
Description  
• Two Operating Modes  
The CDP1854A/3 and CDP1854AC/3 are high reliability  
silicon gate CMOS Universal Asynchronous Receiver/Trans-  
mitter (UART) circuits. 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/3 is capable of full  
duplex operation, i.e., simultaneous conversion of serial  
input data to parallel output 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  
• Fully Programmable with Externally Selectable Word  
Length (5-8 Bits), Parity Inhibit, Even/Odd Parity, and  
1, 1-1/2, or 2 Stop Bits  
The CDP1854A/3 UART can be programmed to operate in  
one of two modes by using the mode control input. When the  
mode input is high (MODE = 1), the CDP1854A/3 is directly  
compatible with the CDP1800 series microprocessor system  
without additional interface circuitry. When the mode input is  
low (MODE = 0), the device is functionally compatible with  
industry standard UARTs 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/3 and the CDP1854AC/3 are functionally  
identical. The CDP1854A/3 has a recommended operating  
voltage range of 4V to 10.5V, and the CDP1854AC/3 has a  
recommended operating voltage range of 4V to 6.5V.
