Product Summary
The ST16C550CJ is a universal asynchronous receiver and transmitter with 16 byte transmit and receive FIFO. A programmable baud rate generator is pro- vided to select transmit and receive clock rates from 50 bps to 1.5 Mbps. The ST16C550CJ is an improved version of the NS16C550 UART with higher operating speed and lower access time. The ST16C550CJ 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 ST16C550CJ provides internal loop-back capability for on board diagnostic testing.
