1M X 8 Bit / 512K X 16 Bit CMOS 3.0 Volt-only, Boot Sector Flash Memory

AMIC Technology 

A29L800A Series

After a program or erase cycle has been completed, the device

is ready to read array data or accept another command.

The sector erase architecture allows memory sectors to be

erased and reprogrammed without affecting the data contents

of other sectors. The A29L800A is fully erased when shipped

from the factory.

The Erase Suspend/Erase Resume feature enables the user

to put erase on hold for any period of time to read data from,

or program data to, any other 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 device offers two power-saving features. When addresses

have been stable for a specified amount of time, the device

enters the automatic sleep mode. The system can also place

the device into the standby mode. Power consumption is

greatly reduced in both these modes.
