TABLE 4. MX29LV040C BUS OPERATION
NOTES:
1. Manufacture and device codes may also be accessed via a command register write sequence. Refer to Table 3.
2. VID is the Silicon-ID-Read high voltage, 11.5V to 12.5V.
3. Refer to Table 3 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/XX00H means unprotected.
Code=01H/XX01H means protected.
6. A18~A13=Sector address for sector protect.
sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while the
Sector Erase operation is in progress.
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 3 defines the valid register command
