ST16C454 QUAD UNIVERSAL ASYNCHRONOUS RECEIVER/TRANSMITTER (UART)
The ST16C454 is a universal asynchronous receiver and transmitter (UART) with a dual foot print interface.The 454 is an enhanced UART with data rates up to1.5Mbps and software compatible to ST16C450.Onboard status registers provide the user with error indications, operational status, and modem interface control. System interrupts may be tailored to meet user requirements. An internal loop-back capability allows onboard diagnostics. The ST16C454 offer an additional68 mode which allows easy integration with Motorola,and other popular microprocessors. The 454 combines the package interface modes of the ST16C454 on a single integrated chip with a selection pin.
