Product Summary
The ST16C550CJ44-F 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 ST16C550CJ44-F is an improved version of the NS16C550 UART with higher operating speed and lower access time. The ST16C550CJ44-F 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 ST16C550CJ44-F provides internal loop-back capability for on board diagnostic testing.
