Function
A19~A0
Address Inputs
To provide memory addresses. During sector erase A19~A11 address lines will select the
sector. During block erase A19~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 inter-
nally 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.
VCC
Power Supply
To provide 3-volt supply ( 2.7V-3.6V ).
