STK16C88 32Kx8 AutoStore+ nvSRAM FEATURES 25, 45 ns Read Access & R/W Cycle Time Unlimited Read/Write Endurance Directly replaces battery-backed SRAM modules such as Dallas/Maxim DS1230 AB 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 1 Million STORE Cycles 100-Year Non-volatile Data Retention Single 5V ± 10% Power Supply Commercial and Industrial Temperatures 28-pin 600-mil PDIP Package (RoHS-Compliant) DESCRIPTION The Simtek STK16C88 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.
