(5) Sector/Chip Erase

This command is sent with the sector address(A19~A13) when operating Sector Erase. The device will start the erase

sequence after CS goes high without any further input. A sector should be erased in a typical of 300ms. The average current

is less than 10mA. The chip erase operation does not require the sector address input but two extra dummy bytes are

necessary. During this operation, customer can also access Read Status & Read ID operations.

(6) Page Program

This command is sent with the page number(A19~A7), and byte address(A6~A0), followed by programming data. One to

128 bytes of data can be loaded into the buffer of the device until CS goes high. IF the end of the page is reached, then

the device will wrap around to the beginning of the page. The device will program the specified page with buffered data(Until

CS goes high) without any further input. The typical page program time is 5ms. The average current is less than 10mA.

During this operation, customer can also access Read Status & Read ID operations.

(7) Standby Mode

When CS is high and there is no operation in progress, the device is put in standby mode. Typical standby current is less

than 30uA.

POWER-ON STATE

After power-up, the device is placed in the standby state with following status:

The status register is reset with following status :

Bit 7 = "1" -----> Refer to page 5 for detail.

Bit 6,5,2,1 = Reserve for future use.

Bit 4 = "0" -----> Erase error flag is reset.

Bit 3 = "0" -----> Program error flag is reset.

Bit 0="1" -----> Device is in ready state.
