The SRAM can be read and written an unlimited number of times, while independent, non- volatile data resides in the nonvolatile elements. Data transfers from the SRAM to the nonvolatile ele- ments (the STORE operation) can take place auto- matically on power down. A 68 µF or larger capacitor tied from V CAP 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. Initiation of STORE and RECALL cycles can also be software controlled by entering specific read sequences. A hardware STORE may be initiated with the HSB pin.
