1.6 Pin Description
NOTE :
Connect all VCC and VSS pins of each device to common power supply outputs.
Pin Name
Pin Function
I/O0 ~ I/O7
DATA INPUTS/OUTPUTS
The I/O pins are used to input command, address and data, and to output data during read operations. The I/O pins float to
high-z when the chip is deselected or when the outputs are disabled.
CLE
COMMAND LATCH ENABLE
The CLE input controls the activating path for commands sent to the command register. When active high, commands are
latched into the command register through the I/O ports on the rising edge of the WE signal.
ALE
ADDRESS LATCH ENABLE
The ALE input controls the activating path for address to the internal address registers. Addresses are latched on the rising
edge of WE with ALE high.
CE
CHIP ENABLE
The CE input is the device selection control. When the device is in the Busy state, CE high is ignored, and the device does
not return to standby mode in program or erase operation.
RE
READ ENABLE
The RE input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid tREA after the fall-
ing edge of RE which also increments the internal column address counter by one.
WE
WRITE ENABLE
The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of the WE pulse.
WP
WRITE PROTECT
The WP pin provides inadvertent program/erase protection during power transitions. The internal high voltage generator is
reset when the WP pin is active low.
R/B
READY/BUSY OUTPUT
The R/B output indicates the status of the device operation. When low, it indicates that a program, erase or random read
operation is in process and returns to high state upon completion. It is an open drain output and does not float to high-z con-
dition when the chip is deselected or when outputs are disabled.
Vcc
POWER
VCC is the power supply for device.
Vss
GROUND
N.C
NO CONNECTION
