28F008SA
Data Protection
Depending on the application the system designer
may choose to make the VPP power supply switcha-
ble (available only when memory byte writesblock
erases are required) or hardwired to VPPH When
VPP e VPPL memory contents cannot be altered
The 28F008SA Command User Interface architec-
ture provides protection from unwanted byte write or
block erase operations even when high voltage is
applied to VPP Additionally all functions are dis-
abled whenever VCC is below the write lockout volt-
age VLKO or when RP
is at VIL The 28F008SA
accommodates either design practice and encour-
ages optimization of the processor-memory inter-
face
The two-step byte writeblock erase Command User
Interface write sequence provides additional soft-
ware write protection
BUS OPERATION
Flash memory reads erases and writes in-system
via the local CPU All bus cycles to or from the flash
memory conform to standard microprocessor bus
cycles
Read
The 28F008SA has three read modes The memory
can be read from any of its blocks and information
can be read from the intelligent identifier or Status
Register VPP can be at either VPPL or VPPH
The first task is to write the appropriate read mode
command to the Command User Interface (array in-
telligent
identifier
or
Status
Register)
The
28F008SA automatically resets to Read Array mode
upon initial device powerup or after exit from deep
powerdown The 28F008SA has four control pins
two of which must be logically active to obtain data
at the outputs Chip Enable (CE ) is the device se-
lection control and when active enables the select-
ed memory device Output Enable (OE ) is the data
inputoutput (DQ0–DQ7) direction control and when
active drives data from the selected memory onto
the IO bus RP
and WE
must also be at VIH
Figure 10 illustrates read bus cycle waveforms
Output Disable
With OE
at a logic-high level (VIH) the device out-
puts are disabled
Output pins (DQ0–DQ7) are
placed in a high-impedance state
Standby
CE
at a logic-high level (VIH) places the 28F008SA
in standby mode Standby operation disables much
of the 28F008SA’s circuitry and substantially reduc-
es device power consumption The outputs (DQ0
DQ7) are placed in a high-impedence state indepen-
dent of the status of OE
If the 28F008SA is dese-
lected during block erase or byte write the device
will continue functioning and consuming normal ac-
tive power until the operation completes

1 Refer to DC Characteristics When VPP e VPPL memory contents can be read but not written or erased
2 X can be VIL or VIH for control pins and addresses and VPPL or VPPH for VPP See DC Characteristics for VPPL and VPPH

is VOL when the Write State Machine is executing internal block erase or byte write algorithms It is VOH when
the WSM is not busy in Erase Suspend mode or deep powerdown mode
4 Command writes involving block erase or byte write are only successfully executed when VPP e VPPH
5 Refer to Table 3 for valid DIN during a write operation
