ST16C454 Quad UART with a Dual Foot Print Interface
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 to 1.5Mbps and software compatible to ST16C450. Onboard status registers provide the user with error indications and operational status, modem interface control. System interrupts may be tailored to meet user requirements. An internal loop-back capability allows onboard diagnostics. The ST16C454 offer an additional 68 mode which allows easy integration with Motorola, and other popular microprocessors. The 454 combines the package interface modes of the ST16C454 and ST68C454 series on a single integrated chip.
