GENERAL DESCRIPTION (cont.)
The Sector Erase Architecture allows memory sectors to be erased
and reprogrammed without affecting the data contents of other sectors.
The device is fully erased when shipped from the factory.
Hardware Data Protection measures include a low VCC detector
that automatically inhibits write operations during power transitions. The
Hardware Sector Protection feature disables both program and erase
operations in any combinations of the sectors of memory. This can be
achieved via programming equipment.
The Erase Suspend feature enables the user to put erase on hold for
any period of time to read data from, or program data to, any sector
that is not selected for erasure. True background erase can thus be
achieved.
The Hardware RESET\ pin terminates any operation in progress
and resets the internal state machine to reading array data. The
RESET\ pin may be tied to the system reset circuitry. A system reset
would thus also reset the device, enabling the system microprocessor to
read the boot-up firmware from the FLASH memory.
The system can place the device into the standby mode. Power
consumption is greatly reduced in this mode.
