ST16C450 - UNIVERSAL ASYNCHRONOUS RECEIVER/TRANSMITTER (UART)

General Description

The ST16C450 is a universal asynchronous receiver and transmitter.

The ST16C450 is an improved version of the NS16450 UART with higher operating speed and lower access time.

A programmable baud rate generator is provided to select transmit and receive clock rates from 50 Bps to 1.5 Mbps.

Key Features

  • Pin to pin and functionally compatible to the Industry Standard 16450.
  • 2.97 to 5.5 volt operation.
  • 1.5 Mbps transmit/receive operation (24MHz).
  • Programmable word lengths (5, 6, 7, 8).
  • Even, odd, force, or no parity generation and detection.
  • Independent transmit and receive control.
  • Standard modem interface.
  • Low operating current ( 1.2mA typ. ).

ST16C450 UNIVERSAL ASYNCHRONOUS RECEIVER/TRANSMITTER (UART) September 2003 GENERAL DESCRIPTION The ST16C450 is a universal asynchronous receiver and transmitter. The ST16C450 is an improved version of the NS16450 UART with higher operating speed and lower access time. A programmable baud rate generator is provided to select transmit and receive clock rates from 50 Bps to 1.5 Mbps. The ST16C450 on board status registers provides the error conditions, type and status of the transfer operation being performed. Included is complete MODEM control capability, and a processor interrupt system that may be software tailored to the user’s requirements. The ST16C450 provides internal loopback capability for on board diagnostic testing.
