ST16C1451 Overview
The ST16C1450, ST16C1451 series (here on denoted as the 145X) is a universal asynchronous receiver and transmitter (UART). The 145X is foot print patible to the SSI 73M1550 and SSI 73M2550 UART with one byte FIFO and higher operating speed and lower access time. The 145X provides enhanced UART functions with a modem control interface, independent programmable baud rate generators with clock rates to 1.5 Mbps.
