MBM29LV400TC/BC Extended Command Definitions

SPA : Sector address to be protected. Set sector address (SA) and (A6, A1, A0) = (0, 1, 0).

SD : Sector protection verify data. Output 01h at protected sector addresses and output 00h at unprotected

sector addresses.

*1: This command is valid while Fast Mode.

*2: This command is valid while RESET= VID.

*3: This data “00h” is also acceptable.

MBM29LV400TC/400BC Sector Protection Verify Autoselect Codes

*1: A-1 is for Byte mode. In byte mode, DQ8 to DQ14 become “High-Z” and DQ15 becomes the lower address A-1.

*2: Outputs 01h at protected sector addresses and outputs 00h at unprotected sector addresses.

Extended Autoselect Code Table

(B): Byte mode

(W): Word mode

HI-Z : High-Z

* : At Byte mode, DQ8 to DQ14 are High-Z and DQ15 is A-1, the lowest address.
