SC16C2550B 5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.), with 16-byte FIFOs

The SC16C2550B is a two channel 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 5 Mbit/s.

The SC16C2550B is pin compatible with the ST16C2550. It will power-up to be functionally equivalent to the 16C2450. The SC16C2550B provides enhanced UART functions with 16-byte FIFOs, modem control interface, DMA mode data transfer. The DMA mode data transfer is controlled by the FIFO trigger levels and the RXRDYn and TXRDYn signals. On-board status registers provide the user with error indications and operational status. System interrupts and modem control features may be tailored by software to meet specific user requirements. An internal loopback capability allows on-board diagnostics. Independent programmable baud rate generators are provided to select transmit and receive baud rates.

The SC16C2550B operates at 5 V, 3.3 V and 2.5 V and the industrial temperature range, and is available in plastic PLCC44, LQFP48, DIP40 and HVQFN32 packages
