DEVICEOPERATION
The M28F201 FLASHMemory product employs a
technologysimilar to a 2 Megabit EPROM but add
to the device functionality by providing electrical
erasure and programming. These functions are
managed by a command register. The functions
that are addressed via the command register de-
pend on the voltage applied to the V
PP
, program
voltage, input. When V
PP
is less than or equal to
6.5V, the command register is disabled and the
M28F201 functionsas a read only memory provid-
ing operating modes similar to an EPROM (Read,
Output Disable, Electronic Signature Read and
Standby).WhenV
PP
israisedto 12Vthecommand
register is enabled and this provides, in addition,
Eraseand Programoperations.
READ ONLY MODES, V
PP
≤
6.5V
For all Read Only Modes, except Standby Mode,
the Write Enable input W should be High. In the
StandbyMode thisinput is ’don’tcare’.
ReadMode.
TheM28F201has twoenableinputs,
E and G, both of which must be Low in order to
outputdatafrom the memory. The Chip Enable(E)
is the power control and shouldbe used for device
selection. Output Enable (G) is the output control
and should be used to gate data on to the output,
independantof the device selection.
