NOTES:
1. Each SLCC contains two FLASH memory devices enabled by
separate chip enables. Typically this module would be used as a
x16 device with CE0 and CE1 tied together. When writing
commands to the Command Register under these conditions, the
command shown in the Command Definition Table should be
duplicated to each byte (I/O0 - I/O7, I/O8 - I/O15) of the module.
If the command to be written is 40H like that for Setup
Program/Program, 4040H would be written to the module followed
by the 16 bit data. A single device can be programmed or erased
by writing the appropriate command to the device the operation is
to be performed on while 00H is written to the other devices that
are enabled at the same time.
Care must be taken when doing Program Verify on a single device.
Make certain that no other devices are driving the data bus of the
devices that are not being verified but are enabled along with the
device that is being verified. Any device that is enabled during
Program Verify will be driving the data bus with the data that is
programmed at that address.
2. All voltages are with respect to VSS.
3. -2.0V min. for pulse width less than 20ns (VIL min. = -0.5V at DC
level).
4. Maximum DC voltage on VPP or A9 may over shoot to +14.0V for
periods less than 20ns.
5. Output shorted for no more than 1 second. No more than one
output shorted at a time.
6. Stresses greater than those under
ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
7. This parameter is guaranteed and not 100% tested.
8. Transition is measured at the point of ±500mV from steady state
voltage.
9. Chip Enable Controlled Writes: Write operations are driven by
the valid combination of Chip Enable and Write Enable. In systems
where Chip Enable defines the write pulse width (within a longer
Write Enable timing waveform)
all Set-up, Hold, and inactive Write
Enable times should be measured relative to the Chip Enable
waveform.
