The data is then clocked out serially. The address
pointer is automaticallyincremented after the data
is output and, if the Chip Select input (S) is held
High, the ST93CS66/67 can output a sequential
streamof data words. In this way, the memory can
be read as a data stream of 16 to 4096 bits, or
continuouslyas the addresscounterautomatically
rolls over to 00 when the highest address is
reached.
Within the time required by a programming cycle
(t
W
), up to 4 words may be written with the help of
the PageWrite instruction; the whole memory may
alsobe erased,or set to a predeterminedpattern,
by using the Write All instruction.
Within the memory, an user defined area may be
protected against further Write instructions. The
size of this area is defined by the content of a
Protect Register, located outside of the memory
array. As a final protection step, data may be per-
manently protected by programming a One Time
Programing bit (OTP bit) which locks the Protect
Register content.
Programming is internally self-timed (the external
clocksignal on Cinput may be disconnectedor left
running after the start of a Write cycle) and does
notrequirean erasecycle priorto the Writeinstruc-
tion.The Writeinstructionwrites 16bitsat onetime
into one of the 256 words,the PageWrite instruc-
tion writes up to 4 words of 16 bits to sequential
locations, assuming in both cases that all ad-
dressesareoutsidetheWrite Protectedarea.After
the start of the programming cycle, a Ready/Busy
signalis availableon the Data output (Q)when the
ChipSelect (S) input pin is driven High.

Notes:
1. Except for the rating ”O(jiān)perating Temperature Range”, stresses above those listed in the Table ”Absolute MaximumRatings”
may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other
conditions abovethose indicated in the Operating sectionsof this specification is not implied. Exposure to Absolute Maximum
Rating conditions for extended periods may affect device reliability.Refer also to the SGS-THOMSON SURE Program and other
relevant quality documents.
