6 / 28 page Description M93S66-125 M93S56-125 M93S46-125 6/28 Doc ID 022567 Rev 1 Chip Select Input (S) is held High, the M93Sx6-125 can output a sequential stream of data words. In this way, the memory can be read as a data stream from 16 to 4096 bits (for the M93S66-125), or continuously as the address counter automatically rolls over to 00h when the highest address is reached. Within the time required by a programming cycle (tW), up to 4 words may be written with 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, a user defined area may be protected against further Write instructions. The size of this area is defined by the content of a Protection register, located outside of the memory array. As a final protection step, data may be permanently protected by programming a One Time Programming (OTP) bit which locks the Protection register content. Programming is internally self-timed (the external clock signal on Serial Clock (C) may be stopped or left running after the start of a Write cycle) and does not require an erase cycle prior to the Write instruction. The Write instruction writes 16 bits at a time into one of the word locations of the M93Sx6-125, the Page Write instruction writes up to 4 words of 16 bits to sequential locations, assuming in both cases that all addresses are outside the Write protected area. After the start of the programming cycle, a Busy/Ready signal is available on Serial Data Output (Q) when Chip Select Input (S) is driven High. An internal Power-on Data Protection mechanism in the M93Sx6-125 inhibits the device when the supply is too low.
