description

The TL16C554 and the TL16C554I are enhanced quadruple versions of the TL16C550B asynchronous

communications element (ACE). 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 at any time during functional

operation by the CPU. The information obtained includes the type and condition of the operation performed and

any error conditions encountered.

The TL16C554 and the TL16C554I 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. To minimize system overhead and maximize system efficiency, all logic is on

the chip. Two terminal functions allow signaling of direct memory access (DMA) transfers. Each ACE includes

a programmable baud rate generator that can divide the timing reference clock input by a divisor between 1 and

(2 −1).

The TL16C554 and the TL16C554I are available in a 68-pin plastic-leaded chip-carrier (PLCC) FN package and

in an 80-pin (TQFP) PN package.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
