Fonctionnalités et applications

The SC16C550B is a Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data, and vice versa. The UART can handle serial data rates up to 3 Mbit/s.

The SC16C550B is pin compatible with the ST16C550, TL16C550 and PC16C550, and it will power-up to be functionally equivalent to the 16C450. The SC16C550B also provides DMA mode data transfers through FIFO trigger levels and the TXRDY and RXRDY signals (TXRDY and RXRDY are not supported in the HVQFN32 package). On-board status registers provide the user with error indications, operational status, and modem interface control. System interrupts may be tailored to meet user requirements. An internal loopback capability allows on-board diagnostics.

The SC16C550B operates at 5 V, 3.3 V and 2.5 V, and the Industrial temperature range, and is available in plastic HVQFN32, DIP40, PLCC44 and LQFP48 packages.


  • 5 V, 3.3 V and 2.5 V operation

  • After reset, all registers are identical to the typical 16C450 register set
  • Capable of running with all existing generic 16C450 software
  • Pin compatibility with the industry-standard ST16C450/550, TL16C450/550, PC16C450/550
  • Up to 3 Mbit/s transmit/receive operation at 5 V, 2 Mbit/s at 3.3 V, and 1 Mbit/s at 2.5 V
  • 5 V tolerant on input only pins1
  • 16 byte transmit FIFO
  • Automatic hardware flow control
  • Software selectable baud rate generator
  • Four selectable Receive FIFO interrupt trigger levels
  • Standard modem interface
  • Standard asynchronous error and framing bits (Start, Stop, and Parity Overrun Break)
  • Independent receiver clock input
  • Transmit, Receive, Line Status, and Data Set interrupts independently controlled
  • 16 byte receive FIFO with error flags
