25, 45 ns Read Access & R/W Cycle Times Unlimited Read/Write Endurance Automatic Non-Volatile STORE on Power Loss Non-Volatile STORE Under Hardware Control Automatic RECALL to SRAM on Power Up Unlimited RECALL Cycles 1 Million STORE Cycles 100-Year Non-volatile Data Retention Single 5V + 10% Operation Commercial, Industrial, and Military Temperatures 28-Pin 300 mil SOIC or 330 mil SOIC (RoHSCompliant) DESCRIPTION The Simtek STK22C48 is a 16Kb fast static RAM with a nonvolatile 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. 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.
