TL16C550BI ACE

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 ov.
