description
The TL16C550B and the TL16C550BI are functional upgrades of the TL16C450 asynchronous
communications element (ACE). Functionally identical to the TL16C450 on power up (character mode
), the
TL16C550B and TL16C550BI can be placed in an alternate mode (FIFO) to relieve the CPU of excessive
software overhead.
In this alternate FIFO mode, internal FIFOs are activated allowing 16 bytes (plus 3 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 of the TL16C450 terminal functions (RXRDY and
TXRDY) have been changed to allow signalling of DMA transfers.
The TL16C550B and the TL16C550BI perform serial-to-parallel conversions on data received from a peripheral
device or modem and parallel-to-serial conversion on data received from its CPU. The CPU can read and report
on the status of the ACE at any point in the ACE operation. Reported status information includes: the type of
transfer operation in progress, the status of the operation, and any error conditions encountered.
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.
The TL16C550B and the TL16C550BI can also be reset to the TL16C450 mode under software control.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
