EOL Data Sheet

TABLE 3: PIN DESCRIPTION

Symbol Name

Functions

A19-A0

Address Inputs

To provide memory addresses. During Sector-Erase and Hardware Sector Protection,

A19-A11 address lines will select the sector. During Block-Erase A19-A15 address

lines will select the block.

DQ14-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.

DQ15/A-1 Data Input/Output

and LBS Address

DQ15 is used as data I/O pin when in x16 mode (BYTE# = “1”)

A-1 is used as the LSB address pin when in x8 mode (BYTE# = “0”)

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

RST#

Hardware Reset

To reset and return the device to Read mode

RY/BY# Ready/Busy#

To output the status of a Program or Erase operation

RY/BY# is a open drain output, so a 10KΩ - 100KΩ pull-up resistor is required

to allow RY/BY# to transition high indicating the device is ready to read.

WP#

Write Protect

To protect and unprotect top or bottom 8 KWord (4 outermost sectors) from Erase or

Program operation.

BYTE# Word/Byte Configuration To select 8-bit or 16-bit mode.

VDD

Power Supply

VSS

Ground

To provide 2.7-3.6V power supply voltage

NC

No Connection

Unconnected pins
