DESCRIPTION
The ST16C452/ST16C452PS (452/452PS) 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 452/452PS provides enhanced UART functions, a modem control interface, and data rates up to 1.5Mbps. Onboard status registers provide the user with error indications and operational status. The system interrupts and control may be tailored to meet user requirements. An internal loop-back capability allows onboard diagnostics.

FEATURES
Added features in devices with top mark date code of "F2 YYWW" and newer:
 • 5V Tolerant Inputs
 • Pin to pin and functional compatible to TL16C452
 • 2.97 to 5.5 volt operation
 • Software compatible with ST16C450, NS16C450
 • 1.5 Mbps transmit/receive operation (24MHz)
 • Independent transmit and receive control
 • Modem and printer status registers
 • UART port and printer port Bi-directional
 • Printer port direction set by single control bit or 8 bit pattern (AA/55)
 • Modem control signals (-CTS, -RTS, -DSR, -DTR, -RI, -CD)
 • Programmable character lengths (5, 6, 7, 8)
 • Even, odd, or no parity bit generation and detection
 • Internal loop-back diagnostics
 • TTL compatible inputs, outputs
 • Low Power
