Functions

AMS1-A0

1. AMS = Most significant address

AMS = A16 for SST39LF/VF010, A17 for SST39LF/VF020, and A18 for SST39LF/VF040

Address Inputs

To provide memory addresses. During Sector-Erase AMS-A12 address lines will

select the sector. During Block-Erase AMS-A16 address lines will select the block.

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 power supply voltage:

3.0-3.6V for SST39LF010/020/040

2.7-3.6V for SST39VF010/020/040

VSS

Ground

NC

No Connection

Unconnected pins.
