Infineon CY22E016L-SZ35XC

The Cypress CY22E016L is a fast static RAM with a nonvolatile element incorporated in each static memory cell. The SRAM is read and written an infinite number of times, while independent, nonvolatile data resides in nonvolatile elements. Data transfers from the SRAM to the nonvolatile elements (the STORE operation) takes place automatically on power down. A 68 μF or larger capacitor tied from VCAP to ground guarantees the STORE operation, regardless of power down slew rate or loss of power from “hot swapping.” Transfers from the nonvolatile elements to the SRAM (the RECALL operation) take place automatically on restoration of power. A hardware STORE is initiated with the HSB pin.
