Pin Name

Address Inputs

Functions

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
