Product Summary
The STK15C88-NF45I is a 256Kb fast static RAM with a non-volatile Quantum Trap storage element included with each memory cell. The STK15C88-NF45I 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 STOREoperation). On power up, data is automatically restored to the STK15C88-NF45I (the RECALL operation). The STK15C88-NF45I 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.
