ST16C550CJ44-F

产品概述

The ST16C550CJ44-F is an Universal Asynchronous Receiver And Transmitter with 16 byte transmit and receive FIFO. It operates at 2.97 to 5.5V. A programmable baud rate generator can select transmit and receive clock rates from 50bps to 1.5Mbps. The ST16C550 is an improved version of the NS16C550 UART with higher operating speed and lower access time. The ST16C550 on board status registers provides the error conditions, type and status of the transfer operation being performed. It includes complete MODEM control capability and a processor interrupt system that may be software tailored to the user’s requirements. The ST16C550 provides internal loopback capability for on board diagnostic testing.
