TL16PC564BPZ

Product Summary

The TL16PC564BPZ is a pcmcia universal asynchronous receiver transmitter. The TL16PC564BPZ is designed to provide all the functions necessary for a Personal Computer Memory Card International Association (PCMCIA) universal asynchronous receiver transmitter (UART) subsystem interface. The TL16PC564BPZ provides a serial-to-parallel conversion for data to and from a modem coder-decoder/digital signal processor (CODEC/DSP) function to a PCMCIA parallel data-port format. A computer central processing unit (CPU), through a PCMCIA host controller, can read the status of the asynchronous communications element (ACE) interface at any point in the operation. Reported status information includes the type of transfer operation in process, the status of the operation, and any error conditions encountered.
