TL16C554AIPN

UART интерфейс, 4 канала, 1 Мбит/с, 4.75 В, 5.25 В, LQFP, 80 вывод(-ов).

The TL16C554AIPN is an Asynchronous Communications Element features that each channel performs serial-to-parallel conversion on data characters received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted by the CPU. The complete status of each channel of the quadruple ACE can be read by the CPU at any time during operation. The information obtained includes the type and condition of the operation performed and any error conditions encountered. The TL16C554A quadruple ACE can be placed in an alternate FIFO mode, which activates the internal FIFOs to allow 16 bytes (plus three bits of error data per byte in the receiver FIFO) to be stored in both receive and transmit modes. In the FIFO mode of operation, there is a selectable auto-flow control feature that can significantly reduce software overhead and increase system efficiency by automatically controlling serial-data flow using RTS output and CTS input signals.
