Functional Description
(Continued)
Write (WRITE):
The WRITE instruction is followed by 16 bits of data to be
written into the specificed address. After the last bit of data
is put on the data-in (DI) pin, CS must be brought low before
the next rising edge of the SK clock. This falling edge of CS
initiates the self-timed programming cycle. The DO pin indi-
cates the READY/BUSY status of the chip if CS is brought
high after the t
CS
interval. DO
e
logical 0 indicates that
programming is still in progress. DO
e
logical 1 indicates
that the register at the address specified in the instruction
has been written with the data pattern specified in the in-
struction and the part is ready for another instruction.
Erase All (ERAL):
The ERAL instruction will simultaneously program all regis-
ters in the memory array and set each bit to the logical ‘‘1’’
state. The Erase All cycle is identical to the ERASE cycle
except for the different op-code. As in the ERASE mode,
the DO pin indicates the READY/BUSY status of the chip if
CS is brought high after the t
CS
interval.
Write All (WRALL):
The WRALL instruction will simultaneously program all reg-
isters with the data pattern specified in the instruction. As in
the WRITE mode, the DO pin indicates the READY/BUSY
status of the chip if CS is brought high after the t
CS
interval.
Write Disable (WDS):
To protect against accidental data distrub, the WDS instruc-
tion disables all programming modes and should follow all
programming operations. Execution of a READ instruction is
independent of both the WEN and WDS instructions.
Note:
NSC CMOS EEPROMs do not require an ‘‘ERASE’’ or ‘‘ERASE ALL’’ operation prior to the ‘‘WRITE’’ and ‘‘WRITE ALL’’ instructions. The ‘‘ERASE’’ and
‘‘ERASE ALL’’ instructions are included to maintain compatibility with earlier technology EEPROMs.
