The ST16C6541 is a universal asynchronous receiver and transmitter (UART) with a dual foot print interface compatible with the ST16C554 and ST68C554. The 654 is an enhanced UART with 64 byte FIFOs, automatic hardware/software flow control, 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 loop-back capability allows onboard diagnostics.
The 654 is available in a 64-pin LQFP package. The 64-pin package offers the 16 interface mode which is compatible with the industry standard ST16C554.
The ST16C654DCQ64 provides constant active interrupt outputs. The 64 pin devices do not offer TXRDY/RXRDY outputs or the default clock select option (CLKSEL). The 654 combines the package interface modes of the 16C454/554 and 68/C454/554 series on a single integrated chip.
NOTE: 1 Covered by U.S. Patent #5,649,122.
