Name and Function
BYTE-SELECT ADDRESS:
Selects between high and low byte when
device is in x8 mode. This address is latched in x8 data programs. Not
used in x16 mode (i.e., the A
0
input buffer is turned off when BYTE# is
high).
WORD-SELECT ADDRESSES:
Select a word within one 64-Kbyte block.
A
6-15
selects 1 of 1024 rows, and A
1-5
selects 16 of 512 columns. These
addresses are latched during data programs.
BLOCK-SELECT ADDRESSES:
Select 1 of 32 erase blocks in each of
the two 28F016SAs. These addresses are latched during data programs,
block erase and lock block operations.
LOW-BYTE DATA BUS:
Inputs data and commands during CUI write
cycles. Outputs array, buffer, identifier or status data in the appropriate
read mode. Floated when the chip is de-selected or the outputs are
disabled.
HIGH-BYTE DATA BUS:
Inputs data during x16 data program
operations. Outputs array, buffer or identifier data in the appropriate read
mode; not used for Status Register reads. Floated when the chip is de-
selected or the outputs are disabled.

CE

2
# select between the first and second device, respectively
CE
1
# and CE
2
# must not be active low simultaneously. Reference Table
3.0.
RESET/POWER-DOWN:
RP# low places the device in a deep power-
down state. All circuits that burn static power, even those circuits enabled
in standby mode, are turned off. When returning from deep power-down,
a recovery time is required to allow these circuits to power-up.
When RP# goes low, any current or pending WSM operation(s) are
terminated, and the device is reset. All Status Registers return to ready
(with all status flags cleared).
OUTPUT ENABLE:
Gates device data through the output buffers when
low. The outputs float to tri-state off when OE# is high.
NOTE:
CEx# overrides OE#, and OE# overrides WE#.
WRITE ENABLE:
Controls
access to the CUI, Page Buffers, Data Queue
Registers and Address Queue Latches. WE# is active low, and latches
both address and data (command or array) on its rising edge.
READY/BUSY:
Indicates status of the internal WSM. When low, it
indicates that the WSM is busy performing an operation. RY/BY# high
indicates that the WSM is ready for new operations (or WSM has
completed all pending operations), or block erase is suspended, or the
device is in deep power-down mode. This output is always active (i.e., not
floated to tri-state off when OE# or CE
0

#/CE

# are high), except if a
RY/BY#
Pin Disable command is issued.
