rectly.

Typically, this mode provides a 30% reduction in overall programming times. During accelerated programming,

the current drawn from the WP#/ACC pin is no more than ICP1.

TEMPORARY SECTOR UNPROTECT OPERATION

System can apply RESET# pin at Vhv to place the device in temporary unprotect mode. In this mode, previously

protected sectors can be programmed or erased just as it is unprotected. The devices return to normal operation

once Vhv is removed from RESET# pin and previously protected sectors are again protected.

AUTOMATIC SELECT OPERATION

When the device is in Read array mode, erase-suspended read array mode or CFI mode, user can issue read

silicon ID command to enter read silicon ID mode. After entering read silicon ID mode, user can query several

silicon IDs continuously and does not need to issue read silicon ID mode again. When A0 is Low, device will out-

put Macronix Manufacture ID C2h. When A0 is high, device will output Device ID. In read silicon ID mode, issu-

ing reset command will reset device back to read array mode or erase-suspended read array mode.

Another way to enter read silicon ID is to apply high voltage on A9 pin with CE#, OE#, A6 and A1 at Vil. While

the high voltage of A9 pin is discharged, device will automatically leave read silicon ID mode and go back to read

array mode or erase-suspended read array mode. When A0 is Low, device will output Macronix Manufacture ID

C2h. When A0 is high, device will output Device ID.

VERIFY SECTOR PROTECT STATUS OPERATION

MX29LV161D T/B provides hardware sector protection against Program and Erase operation for protected sec-

tors. The sector protect status can be read through Sector Protect Verify command. This method requires Vhv on

A9 pin, Vih on WE# and A1 pins, Vil on CE#, OE#, A6 and A0 pins, and sector address on A12 to AM pins. If the

read out data is 01h, the designated sector is protected. Oppositely, if the read out data is 00h, the designated

sector is not protected.

DATA PROTECTION

To avoid accidental erasure or programming of the device, the device is automatically reset to read array mode

during power up. Besides, only after successful completion of the specified command sets will the device begin

its erase or program operation.

Other features to protect the data from accidental alternation are described as followed.

LOW VCC WRITE INHIBIT

The device refuses to accept any write command when Vcc is less than Vlko. This prevents data from spuriously

altered. The device automatically resets itself when Vcc is lower than Vlko and write cycles are ignored until Vcc

is greater than Vlko. System must provide proper signals on control pins after Vcc is larger than Vlko to avoid un-

intentional program or erase operation.
