1. Speed Options ending in “3” and “8” indicate the “reduced wait-state handshaking” option, which speeds initial synchronous
accesses for even addresses.
2. Speed Options ending in “4” and “9” indicate the “standard handshaking” option.
3. See the AC Characteristics section of this datasheet for full specifications.
