Name and Function
RY/BY#
OPEN DRAIN
OUTPUT
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
1
# are high), except if a
RY/BY# Pin Disable command is issued.
WP#
INPUT
WRITE PROTECT:
Erase blocks can be locked by writing a nonvolatile
lock-bit for each block. When WP# is low, those locked blocks as
reflected by the Block-Lock Status bits (BSR.6), are protected from
inadvertent data programs or block erases. When WP# is high, all blocks
can be written or erased regardless of the state of the lock-bits. The WP#
input buffer is disabled when RP# transitions low (deep power-down
mode).
BYTE#
INPUT
BYTE ENABLE:
BYTE# low places device in x8 mode. All data is then
input or output on DQ
0
–7
, and DQ
8
–15
float. Address A
0
selects between
the high and low byte. BYTE# high places the device in x16 mode, and
turns off the A
0
input buffer. Address A
1
then becomes the lowest order
address.
3/5#
INPUT
3.3/5.0 VOLT SELECT:
3/5# high configures internal circuits for 3.3V
operation. 3/5# low configures internal circuits for 5.0V operation.
NOTES:
Reading the array with 3/5# high in a 5.0V system could damage the
device.
There is a significant delay from 3/5# switching to valid data.
