DescriptionEXAR 16C550C IC I/O Controller | UART with 16-Byte FIFO
OverviewThe ST16C550 (550) is a 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 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. Included is 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.The ST16C550 is available in 40 pin PDIP, 44 pin PLCC, and 48 pin TQFP packages. It is fabricated in an advanced CMOS process to achieve low drain power and high speed requirements.
Key FeaturesPin to pin and functionally compatible to the Industry Standard 16C550 2.97 to 5.5 volt operation 24MHz clock operation at 5V 16MHz clock operation at 3.3V 16 byte transmit FIFO 16 byte receive FIFO with error flags Full duplex operation Transmit and receive control Four selectable receive FIFO interrupt trigger levels Standard modem interface Compatible with ST16C450 Low operating current ( 1.2mA typ.)
