(MBM29DL164TE = 33h and MBM29DL164BE = 35h for ×8 mode; MBM29DL164TE = 2233h and
MBM29DL164BE = 2235h for ×16 mode). These two bytes/words are given in “MBM29DL16XTE/BE Sector

• 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
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 Characteristics” in ■ELECTRICAL CHARACTERISTICS and ■TIMING DIAGRAM.
• Sector Group Protection
The MBM29DL16XTE/BE feature hardware sector group protection. This feature will disable both program and
erase operations in any combination of 17 sector groups of memory. (See “Sector Group Addresses Tables
(MBM29DL16XTE/BE)” in ■FLEXIBLE SECTOR-ERASE ARCHITECTURE). The sector group protection
feature is enabled using programming equipment at the user’s site. The device is shipped with all sector groups
unprotected.
To activate this mode, the programming equipment must force V

ARCHITECTURE define the sector address for each of the thirty nine (39) individual sectors, and “Sector Group
Addresses Tables (MBM29DL16XTE/BE)” in ■FLEXIBLE SECTOR-ERASE ARCHITECTURE define the sector
group address for each of the seventeen (17) individual group 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 group
addresses must be held constant during the WE pulse. See “(15) AC Waveforms for Sector Group Protection”
in ■TIMING DIAGRAM and “(5) Sector Group Protection Algorithm” in ■FLOW CHART for sector group
protection waveforms and algorithm.
To verify programming of the protection circuitry, the programming equipment must force V

It is also possible to determine if a sector group is protected in the system by writing an Autoselect command.
