Programmable Universal Asynchronous Receiver Transmitter (UART) DIP-40

The CDP1854AE is a silicon-gate CMOS Universal Asynchronous Receiver/Transmitter (UART) circuit. It is 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 8-bit CDP1800-series microprocessor parallel data bus system. It's capable of full duplex operation.


  • Two operating modes:
    • 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: 10V DC to 400K Bits/s at VDD
  • 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
  • Temperature range: -40°C to +85°C
  • Package: DIP-40, 0.6" wide
