Pin Name
Function
The I/O pins are used to input command, address and data, and
Data Inputs/Outputs to output data during read operations. The I/O pins float to Hi-Z
when the chip is deselected or when the outputs are disabled.
The CLE input controls the activating path for commands sent to
Command Latch the command register. Commands are latched into the command
Enable
register through the I/O ports on the rising edge of the WE# signal
with CLE high.
The ALE input controls the activating path for address to the
Address Latch
internal address registers. Addresses are latched into the address
Enable
register through the I/O ports on the rising edge of WE# with ALE
high.
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
Chip Enable
return to standby mode in program or erase operation. Regarding
CE# control during read operation, refer to ’Page read’ section of
Device operation.
The RE# input is the serial data-out control, and when it is low, it
Read Enable
active drives the data onto the I/O bus. Data is valid t_REA after the
falling edge of RE# which also increments the internal column
address counter by one.
Write Control
The WE# input controls writes to the I/O port. Commands,
address and data are latched on the rising edge of the WE# pulse.
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.
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 Hi-Z condition
when the chip is deselected or when outputs are disabled.
Power Supply
V_CC is the power supply for device.
Ground
No Connection
Lead is not internally connected.
Note: Connect all V_CC and V_SS pins of each device to common power supply outputs. Do not leave V_CC
or V_SS disconnected.
