2 / 16 page The data is then clocked out serially. The address pointer is automatically incremented after the data is output and, if the Chip Select input (S) is held High, the ST93CS66/67 can output a sequential stream of data words. In this way, the memory can be read as a data stream of 16 to 4096 bits, or continuously as the address counter automatically rolls over to 00 when the highest address is reached. Within the time required by a programming cycle (tW), up to 4 words may be written with the help of the Page Write instruction; the whole memory may also be erased, or set to a predetermined pattern, 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 clock signal on C input may be disconnected or left running after the start of a Write cycle) and does not require an erase cycle prior to the Write instruc- tion. The Write instruction writes 16 bits at one time into one of the 256 words, the Page Write instruc- tion writes up to 4 words of 16 bits to sequential locations, assuming in both cases that all ad- dresses are outside the Write Protected area. After the start of the programming cycle, a Ready/Busy signal is available on the Data output (Q) when the Chip Select (S) input pin is driven High.

Except for the rating ”Operating Temperature Range”, stresses above those listed in the Table ”Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of 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. 2.
