TL16C550B, TL16C550BI Asynchronous Communications Element is capable of running with all existing TL16C450 software and after reset, all registers are identical to the TL16C450 register set.
The TL16C550B and TL16C550BI are functional upgrades of the TL16C450 asynchronous communications element (ACE). They are capable of running with all existing TL16C450 software characteristics but can also operate in an alternate FIFO mode to reduce CPU overhead. In this mode, internal FIFOs allow 16 bytes of data to be stored in both receive and transmit buffers.
| Baud Rate | DC to 562 Kbit/s |
|---|---|
| FIFO Buffer Size | 16-Byte FIFOs |
| Package Types | 40-pin DIP, 44-pin PLCC, 48-pin TQFP |
| Clock Divisor Range | 1 to (2^16 - 1) |
Yes, the TL16C550B and TL16C550BI can be reset to the TL16C450 mode under software control.
The device supports a baud generation rate from DC to 562 Kbit/s.
The generator can divide a reference clock input by divisors from 1 to (2^16 - 1).
In FIFO mode, both the receiver and transmitter are buffered with 16-byte FIFOs.
