Functions

AMS1-A0

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.

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 SST39LF200A/400A/800A

2.7-3.6V for SST39VF200A/400A/800A

VSS

Ground

NC

No Connection Unconnected pins.

1. AMS = Most significant address

AMS = A16 for SST39LF/VF200A, A17 for SST39LF/VF400A, and A18 for SST39LF/VF800A
