STK15C88 32Kx8 PowerStore nvSRAM FEATURES 25, 45 ns Read Access & R/W Cycle Time Unlimited Read/Write Endurance Pin compatible with industry standard SRAMs Automatic Non-volatile STORE on Power Loss Automatic RECALL to SRAM on Power Up Non-Volatile STORE or RECALL under Software Control Unlimited RECALL Cycles 1 Million Store Cycles 100-Year Non-volatile Data Retention Single 5V +10% Power Supply Commercial and Industrial Temperatures 28-pin 300-mil and 330 mil SOIC Packages (RoHS-Compliant) DESCRIPTION The Simtek STK15C88 is a 256Kb fast static RAM with a non-volatile Quantum Trap storage element included with each memory cell. The SRAM provides the fast access & cycle times, ease of use and unlimited read & write endurance of a normal SRAM. Data transfers automatically to the non-volatile storage cells when power loss is detected (the STORE operation). On power up, data is automatically restored to the SRAM (the RECALL operation). Both STORE and RECALL operations are also available under software control. PowerStore nvSRAM products depend on the intrinsic system capacitance to maintain system power long enough for an automatic store on power loss. If the power ramp from 5 volts to 3.6 volts is faster than 10 ms, consider our 14C88 or 16C88 for more reliable operation. The Simtek nvSRAM is the first monolithic non-volatile memory to offer unlimited writes and reads. It is the highest performance, most reliable non-volatile memory available. BLOCK DIAGRAM QUANTU……
