READY/BUSY: Indicates status of the internal WSM. When low, it
indicates that the WSM is busy performing an operation. RY/BY# floating
indicates that the WSM is ready for new operations (or WSM has
completed all pending operations), or 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
Disable command is issued.
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 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 ENABLE: BYTE# low places device in x8 mode. All data is then
input or output on DQ
the high and low byte. BYTE# high places the device in x16 mode, and
turns off the A
address.
3.3/5.0 VOLT SELECT: 3/5# high configures internal circuits for 3.3V
operation. 3/5# low configures internal circuits for 5V operation.
Reading the array with 3/5# high in a 5V system could damage the
device. Reference the power-up and reset timings (Section 5.7) for 3/5#
switching delay to valid data.
PROGRAM/ERASE POWER SUPPLY (12V ± 0.6V, 5V ± 0.5V) : For
erasing memory array blocks or writing words/bytes/pages into the flash
array. V
connection to 12V ± 0.6V maximizes Program/Erase Performance.
Successful completion of program and erase attempts is inhibited with
V
and 4.5V, between 5.5V and 11.4V, and above 12.6V produce spurious
results and should not be attempted.
DEVICE POWER SUPPLY (3.3V ± 0.3V, 5V ± 0.5V, 5.0 ± 0.25V):
To switch 3.3V to 5V (or vice versa), first ramp V
then power to the new V
Do not leave any power pins floating.
GROUND FOR ALL INTERNAL CIRCUITRY:
