Page 3 of 18 STK11C68-5 SMD5962-92324 Device Operation The STK11C68-5 SMD5962-92324 is a versatile memory chip that provides several modes of operation. The STK11C68-5 SMD5962-92324 can operate as a standard 8K x 8 SRAM. It has an 8K x 8 Nonvolatile Elements shadow to which the SRAM information can be copied or from which the SRAM can be updated in nonvolatile mode. SRAM Read The STK11C68-5 SMD5962-92324 performs a Read cycle whenever CE and OE are LOW while WE is HIGH. The address specified on pins determines the 8,192 data bytes accessed. When the Read is initiated by an address transition, the outputs are valid after a delay of tAA Read cycle If the Read is initiated by CE or OE, the outputs are valid at tACE or at tDOE, whichever is later Read cycle The data outputs repeatedly respond to address changes within the tAA access time without the need for transitions on any control input pins. They remain valid until another address change or until CE or OE is brought HIGH, or WE is brought LOW. SRAM Write A Write cycle is performed whenever CE and WE are LOW. The address inputs must be stable before entering the Write cycle and must remain stable until either CE or WE goes HIGH at the end of the cycle. The data on the common I/O pins are written into the memory if it has valid tSD. This is done before the end of a WE controlled Write or before the end of an CE controlled Write. Keep OE HIGH during the entire Write cycle to avoid data bus contention on common I/O lines. If OE is left LOW, internal circuitry turns off the output buffers tHZWE after WE goes LOW. Software STORE Data is transferred from the SRAM to the nonvolatile memory by a software address sequence. The STK11C68-5 SMD5962-92324 software STORE cycle is initiated by executing sequential CE controlled Read cycles from six specific address locations in exact order. During the STORE cycle, an erase of the previous nonvolatile data is first performed followed by a program of the nonvolatile elements. When a STORE cycle is initiated, input and output are disabled until the cycle is completed. Because a sequence of Reads from specific addresses is used for STORE initiation, it is important that no other Read or Write accesses intervene in the sequence. If they intervene, the sequence is aborted and no STORE or RECALL takes place. To initiate the software STORE cycle, the following Read sequence is performed Read address 0x0000, Valid READ address 0x1555, Valid READ address 0x0AAA, Valid READ address 0x1FFF, Valid READ address 0x10F0, Valid READ address 0x0F0F, Initiate STORE cycle The software sequence is clocked with CE controlled Reads. When the sixth address in the sequence is entered, the STORE cycle commences and the chip is disabled. It is important that Read cycles and not Write cycles are used in the sequence. It is not necessary that OE is LOW for a valid sequence. After the tSTORE cycle time is fulfilled, the SRAM is again activated for Read and Write operation.
