NHANCEMENTS
The OX16C954B is an enhanced, backward-compatible revision of the OX16C954 rev A. It uses the newer core as in the
OX16C950 rev B. The chief enhancements are as follows 鈥?/div>
鈥?/div>
All known errata fixed
鈥?/div>
Full TCR range from 4-16
鈥?/div>
Enhanced controls for sleep-mode sensitivity, ability to read FCR and Good Data Status
鈥?/div>
3.3V operation with 80 pin TQFP
鈥?/div>
Enhanced isochronous clocking options (optional inversions, DTR/DSR)
Hereafter OX16C954 rev B is simply referred to as OX16C954.
