Temporary Sector Unprotection
This feature allows temporary unprotection of previously protected sectors of the MBM29F002TC/BC device in
order to change data. The Sector Unprotection mode is activated by setting the RESET pin to high voltage (12
V). During this mode, formerly protected sectors can be programmed or erased by selecting the sector addresses.
Once the 12 V is taken away from the RESET pin, all the previously protected sectors will be protected again.
Refer to Figures 14 and 21.
Notes:
1.Address bits A
11
to A
17
= X = “H” or “L” for all address commands except or Program Address (PA) and
Sector Address (SA).
2.Bus operations are defined in Table 2.
3.RA = Address of the memory location to be read.
PA = Address of the memory location to be programmed. Addresses are latched on the falling edge of
the WE pulse.
SA = Address of the sector to be erased. The combination of A
17
, A
16
, A
15
, A
14
, and A
13
will uniquely select
any sector.
4.RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE.
ID = Device Code (Refer to the section on Sector Protection Verify Autoselect Codes.)
*: Either of the two reset commands will reset the device.
Command Definitions
Device operations are selected by writing specific address and data sequences into the command register.
Writing incorrect address and data values or writing them in the improper sequence will reset the device to the
read mode. Table 6 defines the valid register command sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while the Sector Erase operation is in progress. Moreover, both
Read/Reset commands are functionally equivalent, resetting the device to the read mode.
