The ST16C2550IQ48-F is a dual Universal Asynchronous Receiver And Transmitter (UART) an improved version of the PC16550 UART with higher operating speed and faster access times. The C2550 provides enhanced UART functions with 16 byte FIFO's, a modem control interface and data rates up to 4Mbps. Onboard status registers provide the user with error indications and operational status. System interrupts and modem control features may be tailored by external software to meet specific user requirements. Independent programmable baud rate generators are provided to select transmit and receive clock rates from 50bps to 4Mbps. The baud rate generator can be configured for either crystal or external clock input. An internal loopback capability allows onboard diagnostics. The C2550 is fabricated in an advanced CMOS process capable of operating from 2.97 to 5.5V power supply.

• Up to 1.5Mbps data rate with a 24MHz crystal frequency
• 16 byte Transmit FIFO to reduce the bandwidth requirement of the external CPU
• 16-byte Receive FIFO with error tags to reduce the bandwidth requirement of the external CPU
• 4 Selectable receive FIFO interrupt trigger levels
• Modem control signals (CTS, RTS, DSR, DTR, RI and CD)
• Crystal oscillator or external clock input
