STK11C68-5 (SMD5962-92324) 64 Kbit (8 K x 8) SoftStore nvSRAM Features Functional Description ■ 35 ns, 45 ns, and 55 ns access times ■ Pin compatible with industry standard SRAMs ■ Software initiated nonvolatile STORE ■ Unlimited Read and Write endurance ■ Automatic RECALL to SRAM on power-up ■ Unlimited RECALL cycles ■ 1,000,000 STORE cycles The Cypress STK11C68-5 is a 64 Kb fast static RAM with a nonvolatile element in each memory cell. The embedded nonvolatile elements incorporate QuantumTrap technology to produce the world’s most reliable nonvolatile memory. The SRAM provides unlimited read and write cycles, while independent nonvolatile data resides in the highly reliable QuantumTrap cell. Data transfers under software control from SRAM to the nonvolatile elements (the STORE operation). On power-up, data is automatically restored to the SRAM (the RECALL operation) from the nonvolatile memory. RECALL operations are also available under software control. ■ 100 year data retention For a complete list of related documentation, click here. ■ Single 5 V ± 10% operation ■ Military temperature ■ 28-pin (300 mil) CDIP and 28-pad LCC packages Logic Block Diagram A5 A7 A8 A9 A 11 STATIC RAM ARRAY 128 X 512 RECALL STORE/ RECALL CONTROL DQ 0 DQ 4 DQ 5 DQ 6 A0 - A12 COLUMN I/O COLUMN DEC INPUT BUFFERS DQ 2 DQ 3 HSB SOFTWARE DETECT A 12 DQ 1 VCAP POWER CONTROL STORE ROW DECODER A6 VCC Quantum Trap 128 X 512 A 0 A 1 A 2 A 3 A 4 A 10 DQ 7 OE CE WE Cypress Semiconductor Corporation Document Number: 001-51001 Rev. *E • 198 Champion Court • San Jose, CA 95134-1709 • 408-943-2600 Revised April 2, 2015 STK11C68-5 (SMD5962-92324) Contents Pinouts ..............................................................................

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 A0–12 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 1). If the Read is initiated by CE or OE, the outputs are valid at tACE or at tDOE, whichever is later (Read cycle 2). 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 DQ0–7 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: 1. Read address 0x0000, Valid READ 2. Read address 0x1555, Valid READ 3. Read address 0x0AAA, Valid READ 4. Read address 0x1FFF, Valid READ 5. Read address 0x10F0, Valid READ 6. Read address 0x0F0F, Initiate STORE cycle Document Number: 001-51001 Rev. *E 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. Software RECALL Data is transferred from the nonvolatile memory to the SRAM by a software address sequence. A software RECALL cycle is initiated with a sequence of Read operations in a manner similar to the software STORE initiation. To initiate the RECALL cycle, the following sequence of CE controlled Read operations is performed: 1. Read address 0x0000, Valid READ 2. Read address 0x1555, Valid READ 3. Read address 0x0AAA, Valid READ 4. Read address 0x1FFF, Valid READ 5. Read address 0x10F0, Valid READ 6. Read address 0x0F0E, Initiate RECALL cycle Internally, RECALL is a two step procedure. First, the SRAM data is cleared; then, the nonvolatile information is transferred into the SRAM cells. After the tRECALL cycle time, the SRAM is again ready for Read and Write operations. The RECALL operation does not alter the data in the nonvolatile elements. The nonvolatile data can be recalled for an unlimited number of times. Hardware RECALL (Power Up) During power up or after any low-power condition (VCC < VRESET), an internal RECALL request is latched. When VCC once again exceeds the sense voltage of VSWITCH, a RECALL cycle is automatically initiated and takes tHRECALL to complete. If the STK11C68-5 (SMD5962-92324) is in a Write state at the end of power-up RECALL, the SRAM data is corrupted. To help avoid this situation, a 10 k resistor is connected either between WE and system VCC or between CE and system VCC. Hardware Protect The STK11C68-5 (SMD5962-92324) offers hardware protection against inadvertent STORE operation and SRAM Writes during low voltage conditions. When VCAP < VSWITCH, all externally initiated STORE operations and SRAM Writes are inhibited. Noise Considerations The STK11C68-5 (SMD5962-92324) is a high-speed memory. It must have a high frequency bypass capacitor of approximately 0.1 µF connected between VCC and VSS, using leads and traces that are as short as possible. As with all high-speed CMOS ICs, careful routing of power, ground, and signals reduce circuit noise. Page 4 of 18 STK11C68-5 (SMD5962-92324) Low Average Active Power Figure 4. Current Versus Cycle Time (Write) CMOS technology provides the STK11C68-5 (SMD5962-92324) the benefit of drawing significantly less current when it is cycled at times longer than 50 ns. Figure 3 and Figure 4 shows the relationship between ICC and Read or Write cycle time. Worst case current consumption is shown for both CMOS and TTL input levels (commercial temperature range, VCC = 5.5 V, 100% duty cycle on chip enable). Only standby current is drawn when the chip is disabled. The overall average current drawn by the STK11C68-5 (SMD5962-92324) depends on the following items: ■ Duty cycle of chip enable ■ Overall cycle rate for accesses ■ Ratio of Reads to Writes ■ CMOS versus TTL input levels ■ Operating temperature ■ VCC level Best Practices Cypress nvSRAM products have been used effectively for over 15 years. While ease of use is one of the product’s main system values, the experience gained from working with hundreds of applications has resulted in the following suggestions as best practices: ■ The nonvolatile cells in an nvSRAM are programmed on the test floor during final test and quality assurance. Incoming inspection routines at customer or contract manufacturer’s sites sometimes reprograms these values. Final NV patterns are typically repeating patterns of AA, 55, 00, FF, A5, or 5A. The end product’s firmware must not assume that an NV array is in a set programmed state. Routines that check memory content values to determine first time system configuration. ■ Cold or warm boot status, and so on must always program a unique NV pattern (for example, complex 4-byte pattern of 46 E6 49 53 hex or more random bytes) as part of the final system manufacturing test. This is to ensure these system routines work consistently. I/O loading Figure 3. Current Versus Cycle Time (Read) ■ Table 1.
