MX29LV065B Datasheet, PDF (8/51 Pages) List of Unclassifed Manufacturers – 8M-BIT [1M x 8] CMOS SINGLE VOLTAGE 3V ONLY EQUAL SECTOR FLASH MEMORY

MX29LV081B
COMMAND DEFINITIONS
Device operations are selected by writing specific ad-
dress 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 4 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.

NOTES:
1. Manufacturer and device codes may also be accessed via a command register write sequence. Refer to Table 4.
2. VID is the Silicon-ID-Read high voltage, 11.5V to 12.5V.
3. Refer to Table 4 for valid Data-In during a write operation.
4. X can be VIL or VIH, L=Logic Low=VIL, H=Logic High=VIH.
5. Code=00H means unprotected.
Code=01H means protected.
6. A19~A13=Sector address for sector protect.
7. Sector Protection/Unprotect requires VID on the RESET pin only, and can be implemented either in system or via program-
ming equipment.
