Address Inputs
Data Input/output
To provide memory addresses.
During Sector-Erase AMS-A12 address lines will select the sector.
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
NC
No Connection Unconnected pins.
