The Cypress STK15C88 is a 256Kb fast static RAM with a

nonvolatile element in each memory cell. The embedded

nonvolatile elements incorporate QuantumTrap™ technology

producing the world’s most reliable nonvolatile memory. The

SRAM provides unlimited read and write cycles, while

independent, nonvolatile data resides in the highly reliable

QuantumTrap cell. Data transfers from the SRAM to the

nonvolatile elements (the STORE operation) takes place

automatically at power down. On power up, data is restored to

the SRAM (the RECALL operation) from the nonvolatile memory.

Both the STORE and RECALL 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.
