ST16C552 Datasheet Dual Uart With 16-byte Fifo And Parallel Printer Port

Manufacturer: Exar (now MaxLinear)

Overview: ST16C552 ST16C552A DUAL UART WITH 16-BYTE FIFO AND PARALLEL PRINTER PORT December.

General Description

The ST16C552/ST16C552A (552/552A) is a dual universal asynchronous receiver and transmitter (UART) with an added bi-directional parallel port that is directly compatible with a CENTRONICS type printer.

The parallel port is designed such that the user can configure it as general purpose I/O interface, or for connection to other printer devices.

The 552/552A provides enhanced UART functions with 16 byte FIFO’s, a modem control interface, and data rates up to 1.5Mbps.
