AC CHARACTERISTICS
Alternate CE# Controlled Erase and Program Operations
Notes:
1. Not 100% tested.
2. See the “Erase and Programming Performance” section for
more information.
3. For 1–16 words/1–32 bytes programmed.
4. Effective write buffer specification is based upon a
16-word/32-byte write buffer operation.
5. Word/Byte programming specification is based upon a
single word/byte programming operation not utilizing the
write buffer.
6. AC Specifications listed are tested with V
IO
= V
CC
. Contact
AMD for information on AC operation with V

CC
.
7. When using the program suspend/resume feature, if the
suspend command is issued within t
POLL
, t
POLL
must be fully
re-applied upon resuming the programming operation. If the
suspend command is issued after t
POLL
, t
POLL
is not
required again prior to reading the status bits upon
resuming.
