*1: Address bits A

19

to A

11

= X = “H” or “L” for all address commands except or Program Address (PA) and Sector

Address (SA).

*2: Bus operations are defined in “MBM29LV160T/B User Bus Operation Tables (BYTE = V

IH

and BYTE = V

IL

)”.

*3: RA= Address of the memory location to be read.

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

the WE pulse.

SA= Address of the sector to be erased. The combination of A

19

, A

16

15

, A

14

, A

, and A

will

uniquely select any sector.

*4: RD= Data read from location RA during read operation.

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

*5: The system should generate the following address patterns:

Word Mode: 555h or 2AAh to addresses A

10

to A

0

Byte Mode: AAAh or 555h to addresses A

10

to A

-1

*6: Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.

Note: The command combinations not described in “MBM29LV160T/B Standard Command Definitions” and

“MBM29LV160T/B Extended Command Definitions” are illegal.
