Product Summary

The ST16C550CP is a universal asynchronous receiver and transmitter with 16 byte transmit and receive FIFO. The ST16C550CP operates at 2.97 to 5.5 volts. A programmable baud rate generator can select transmit and receive clock rates from 50 bps to 1.5 Mbps. The ST16C550CP is an improved version of the NS16C550 UART with higher operating speed and lower access time. The ST16C550CP on board status registers provides the error conditions, type and status of the transfer operation being performed. Included is complete MODEM control capability, and a processor interrupt system that may be software tailored to the user’s requirements. The ST16C550CP provides internal loopback capability for on board diagnostic testing.
