ST16C1450 UART with One Byte FIFO
The ST16C1450 series is a universal asynchronous receiver and transmitter (UART). The ST16C1450 is foot print compatible to the SSI 73M1550 and SSI 73M2550 UART with one byte FIFO and higher operating speed and lower access time. The ST16C1450 provides enhanced UART functions with a modem control interface, independent programmable baud rate generators with clock rates to 1.5 Mbps. On board status registers provide the user with error indications and operational status. System interrupts and modem control features may be tailored by external software to meet specific user requirements. An internal loop-back capability allows on board diagnostics. The ST16C1450 is available in a 28-pin PLCC and 48-pin TQFP packages. The baud rate generator can be configured for either crystal or external clock input. The 48-pin TQFP provides a buffered reset output that can be controlled through user software. The ST16C1450 is fabricated in an advanced CMOS process to achieve low drain power and high speed requirements.
