STK16C88-3 32Kx8 AutoStore+ nvSRAM FEATURES Fast 35 ns Read Access & R/W Cycle Time Directly Replaces Battery-Backed SRAM Modules such as Dallas/Maxim DS1230W Unlimited Read/Write Endurance Automatic Non-volatile STORE on Power Loss Automatic RECALL to SRAM on Power Up Non-Volatile STORE and RECALL Under Software Control 1 Million STORE Cycles 100-Year Non-volatile Data Retention Single 3.3V ± 10% Power Supply Commercial and Industrial Temperatures 28-pin 600-mil PDIP Package (RoHS-Compliant) DESCRIPTION The Simtek STK16C88-3 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. 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.
