Product Summary
The ST16C550CQ48-F is an universal asynchronous receiver and transmitter with 16 byte transmit and receive FIFO. It 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 ST16C550CQ48-F is an improved version of the UART with higher operating speed and lower access time.
