Product Summary
The ST16C554DIJ68 is a universal asynchronous receiver and transmitter (UART) with a dual foot print interface. The ST16C554DIJ68 is an enhanced UART with 16 byte FIFOs, receive trigger levels and data rates up to 1.5Mbps. 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 loopback capability allows onboard diagnostics. The ST16C554DIJ68 is available in 64 pin TQFP, and 68 pin PLCC packages. The 68 pin PLCC package offer an additional 68 mode which allows easy integration with Motorola, and other popular microprocessors. The ST16C554DIJ68 (64 pin) offers three state interrupt control while the ST16C554DIJ68 provides constant active interrupt outputs. The 64 pin devices do not offer TXRDY/ RXRDY outputs. The ST16C554DIJ68 combines the package interface modes of the 16C554 and 68C554 series on a single integrated chip.
