1. AMS = Most significant address

AMS = A21 for SST39VF640xB

Address Inputs

To provide memory addresses.

During Sector-Erase AMS-A11 address lines will select the sector.

During Block-Erase AMS-A15 address lines will select the block.

DQ15-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.

To protect the top/bottom boot block from Erase/Program operation when

grounded.

RST#

Reset

To reset and return the device to Read mode.

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 power supply voltage: 2.7-3.6V

VSS

Ground

No Connection
