(Continued)

Legend : Address bits A21 to A15 = X = “H” or “L” for all address commands except for Program Address (PA),

Sector Address (SA) and Sector Group Address (SGA).

Bus operations are defined in “MBM29PL64LM User Bus Operations (Word Mode : BYTE = VIH)”

and “MBM29PL64LM User Bus Operations (Byte Mode : BYTE = VIL)”.

= Address of the memory location to be read.

= Address of the memory location to be programmed. Addresses are latched on the falling edge of

the write pulse.

= Address of the sector to be programmed / erased. The combination of A21, A20, A19, A18, A17, A16,

and A15 will uniquely select any sector. See “Sector Address Table (MBM29PL64LM)”.

SGA = Sector Group Address to be protected. See “Sector Group Address Table (MBM29PL64LM)”.

= Data read from location RA during read operation.

= Data to be programmed at location PA. Data is latched on the rising edge of write plus.

= Sector group protection verify data. Output 01h at protected sector group addresses and output

00h at unprotected sector group addresses.

WBL = Write Buffer Location

HRA = Address of the HiddenROM area ;

Word Mode : 000000h to 000007h

Byte Mode : 000000h to 0000FFh

: The command combinations not described in “MBM29PL64LM Standard Command Definitions” are

illegal.

: Both of these reset commands are equivalent except for "Write to Buffer Abort" reset.

: The Erase Suspend and Erase Resume command are valid only during a sector erase operation.

: The Set to Fast Mode command is required prior to the Fast Program command.

: The Reset from Fast Mode command is required to return to the read mode when the device is in fast mode.

: Reset to the read mode. The Write to Buffer Abert Reset command is required after the Write to Buffer

operation was aborted.

: This command is valid while RESET = VID.

: Sector Group Address (SGA) with A6 = 0, A3 = 0, A2 = 0, A1 = 1, and A0 = 0

: The valid address are A6 to A0.

*10 : The HiddenROM Entry command is required prior to the HiddenROM programming.

*11 : This command is valid during HiddenROM mode.

*12 : The data “F0h” is also acceptable.

*13 : Indicates read cycle.
