Functions

To provide memory addresses. During sector erase A19-A11 address lines

1

will select the sector. During block erase A19-A15 address lines will select

the block.

To output data during read cycles and receive input data during write

2

cycles. Data is internally latched during a write cycle. The outputs are in

tri-state when OE# or CE# is high.

To activate the device when CE# is low.

3

To gate the data output buffers.

To control the write operations.

To provide 3-volt supply (2.7-3.6V)

4

Supplies power for input/output buffers. It should be either tied to VDD

(2.7 - 3.6V) for 3V I/O or to a 5.0V (4.5V - 5.5V) power supply to

support 5V I/O. (Not offered on SST39VF160 device, instead it is a NC)

5

Unconnected pins.
