• Manufacturer Part Number: MX29LV065TC-12
• Description: 64M-BIT [8M x 8] CMOS EQUAL SECTOR FLASH MEMORY
• Manufacturer: MCNIX [Macronix International]

Notes:
1. See Table 1 for descriptions of bus operations.
2. All values are in hexadecimal.
3. Except for the read cycle and fourth cycle of the auto-select command sequence, all bus cycles are write cycles.
4. Unless otherwise noted, address bits A22-A12 are don't cares.
5. No unlock or command cycles required when device is in read mode.
6. The Reset command is required to return to the read mode (or to the erase-suspend-read mode if previously in
7. The fourth cycle of the auto-select command sequence is a read cycle. See the Auto-select Command Sequence
8. The data is 80h for factory locked and 00h for not factory locked.
9. The data is 00h for an unprotected sector group and 01h for a protected sector group.
10. The system may read and program functions in non-erasing sectors, or enter the auto-select mode, when in the
11. The Erase Resume command is valid only during the Erase Suspend mode.
12. Command is valid when device is ready to read array data or when device is in auto-select mode.
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required to
retrieve data. The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The system
can read array data using the standard read timings,
except that if it reads at an address within erase-
suspended sectors, the device outputs status data. After
completing a programming operation in the Erase
Suspend mode, the system may once again read array
data with the same exception. See rase Suspend/Erase
Resume Commands” for more information on this mode.
The system
able the device for reading array data if Q5 goes high, or
while in the auto-select mode. See the "Reset Command"
section, next.
RESET COMMAND
Writing the reset command to the device resets the
device to reading array data. Address bits are don't care
for this command.
The reset command may be written between the

status information).

Erase Suspend mode. The Erase Suspend command is valid only during a sector erase operation.
must
issue the reset command to re-en-

sequence cycles in an erase command sequence before
erasing begins. This resets the device to reading array
data. Once erasure begins, however, the device ignores
reset commands until the operation is complete.
The reset command may be written between the
sequence cycles in a program command sequence before
programming begins. This resets the device to reading
array data (also applies to programming in Erase Suspend
mode). Once programming begins, however, the device
ignores reset commands until the operation is complete.
The reset command may be written between the
sequence cycles in an SILICON ID READ command
sequence. Once in the SILICON ID READ mode, the
reset command

Suspend).
If Q5 goes high during a program or erase operation,
writing the reset command returns the device to reading
array data (also applies during Erase Suspend).
SILICON ID READ COMMAND SEQUENCE
The SILICON ID READ command sequence allows the
host system to access the manufacturer and devices
codes, and determine whether or not a sector is protected.
