Write Pulse
“
Glitch
”
Protection
Noise pulses of less than 5 ns (typical) on OE#, CE#
or WE# do not initiate a write cycle.
Logical Inhibit
Write cycles are inhibited by holding any one of OE# =
V
IL
, CE# = V
IH
or WE# = V
IH
. To initiate a write cycle,
CE# and WE# must be a logical zero while OE# is a
logical one.
Power-Up Write Inhibit
If WE# = CE# = V
IL
and OE# = V
IH
during power up,
the device does not accept commands on the rising
edge of WE#. The internal state machine is automati-
cally reset to the read mode on power-up.
COMMON FLASH MEMORY INTERFACE (CFI)
The Common Flash Interface (CFI) specification out-
lines device and host system software interrogation
handshake, which allows specific vendor-specified
software algorithms to be used for entire families of
devices. Software support can then be device-inde-
pendent, JEDEC ID-independent, and forward- and
backward-compatible for the specified flash device
families. Flash vendors can standardize their existing
interfaces for long-term compatibility.
This device enters the CFI Query mode when the sys-
tem writes the CFI Query command, 98h, to address
55h, any time the device is ready to read array data.
The system can read CFI information at the addresses
given in Tables 6
–
9. To terminate reading CFI data,
the system must write the reset command.
The system can also write the CFI query command
when the device is in the autoselect mode. The device
enters the CFI query mode, and the system can read
CFI data at the addresses given in Tables 6
–
9. The
system must write the reset command to return the de-
vice to the autoselect mode.
For further information, please refer to the CFI Specifi-
cation and CFI Publication 100, available via the
World Wide Web at http://www.amd.com/prod-
ucts/nvd/overview/cfi.html. Alternatively, contact an
AMD representative for copies of these documents.
