Functions

AMS1-A0

Address Inputs

To provide memory addresses.

During Sector-Erase AMS-A12 address lines will select the sector.

DQ7-DQ0

Data Input/output

To output data during Read cycles and receive input data during Write cycles.

Data is internally latched during a Write cycle.

The outputs are in tri-state when OE# or CE# is high.

CE#

Chip Enable

To activate the device when CE# is low.

OE#

Output Enable

To gate the data output buffers.

WE#

Write Enable

To control the Write operations.

VDD

Power Supply

To provide 5.0V supply (4.5-5.5V)

VSS

Ground

No Connection

Unconnected pins.
