1 / 21 page STK14EC16 1 Jan, 2008 Document Control #ML0061 Rev 1.1 This is a product in development that has fixed tar- get specifications that are subject to change pend- ing characterization results. SIMTEK Confidential & Proprietary Preliminary FEATURES • 15, 25, 45 ns Read Access and R/W Cycle Time • Unlimited Read/Write Endurance • Automatic Non-volatile STORE on Power Loss • Non-Volatile STORE Under Hardware or Software Control • Automatic RECALL to SRAM on Power Up • Unlimited RECALL Cycles • 200K STORE Endurance • 20-Year Non-volatile Data Retention • Single 3.0V +20%, -10% Operation • Commercial, Industrial Temperatures • 44-pin or 54-pin 400-mil TSOPII Packages (RoHS- Compliant) • 48-ball Fine Pitch Ball Grid Array (FBGA) DESCRIPTION The Simtek STK14EC16 is a 4MB 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 stor- age 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 highest performance, most reliable non-volatile memory available.
