Functions
A20-A0
Address Inputs
To provide memory addresses. During Sector-Erase and Hardware Sector Protection,
A20-A11 address lines will select the sector. During Block-Erase A20-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.
To gate the data output buffers
OE#
Output Enable
Write Enable
Hardware Reset
Ready/Busy#
WE#
To control the Write operations
RST#
RY/BY#
To reset and return the device to Read mode
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#
VDD
Word/Byte Configuration To select 8-bit or 16-bit mode.
Power Supply
Ground
To provide 2.7-3.6V power supply voltage
