* :Outputs 01H at protected sector addresses and 00H at unprotected sector addresses.
Write
Device erasure and programming are accomplished via the command register. The contents of the register serve
as inputs to the internal state machine. The state machine outputs dictate the function of the device.
The command register itself does not occupy any addressable memory location. The register is a latch used to
store the commands, along with the address and data information needed to execute the command. The
command register is written by bringing WE to V
IL
, while CE is at V
IL
and OE is at V
IH
. Addresses are latched on
the falling edge of WE or CE, whichever happens later; while data is latched on the rising edge of WE or CE,
whichever happens first. Standard microprocessor write timings are used.
Refer to AC Write Characteristics and the Erase/Programming Waveforms for specific timing parameters.
Sector Protection
The MBM29F040C features hardware sector protection. This feature will disable both program and erase
operations in any number of sectors (0 through 8). The sector protection feature is enabled using programming
equipment at the user’s site. The device is shipped with all sectors unprotected.
To activate this mode, the programming equipment must force V
ID
on address pin A
9
and control pin OE, (suggest
V
ID
= 11.5 V) and CE = V
IH
. The sector addresses (A
18
, A
17
and A
16
) should be set to the sector to be protected.
Table 4 defines the sector address for each of the eight (8) individual sectors. Programming of the protection
circuitry begins on the falling edge of the WE pulse and is terminated with the rising edge of the same. Sector
addresses must be held constant during the WE pulse. See figures 11 and 17 sector protection waveforms and
algorithm.
