The device powers on in the read mode. Command sequences are used to place the device in
other operation modes such as program and erase. The device has the capability to protect
the data in any sector (see “Sector Lockdown” section).
To increase the flexibility of the device, it contains an Erase Suspend and Program Suspend
feature. This feature will put the erase or program on hold for any amount of time and let the
user read data from or program data to any of the remaining sectors within the memory. The
end of a program or an erase cycle is detected by the READY/BUSY pin, Data Polling or by
the toggle bit.
The VPP pin provides data protection. When the V
erase functions are inhibited. When V
