ST16C1550 Overview
The ST16C1550 and ST16C1551 UARTs (here on denoted as the ST16C155X) are improved versions of the SSI 73M1550 and SSI 73M2550 UART with higher operating speed and lower access time. The ST16C155X provides enhanced UART functions with 16 byte FIFOs, a modem control interface, independent programmable baud rate generators with clock rates up to 1.5 Mbps. Onboard status registers provide the user with error indications...
