... Document #: 001-06543 Rev. *C PRELIMINARY 64-Kbit ( nvSRAM Functional Description The Cypress CY14E064L is a fast static RAM with a nonvol- atile 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 ® ...

... I/O lines left low, internal circuitry will turn off the output buffers t low. AutoStore Operation The CY14E064L stores data to nvSRAM using one of three storage operations. These three operations are Hardware Store, activated by HSB, Software Store, activated by an address sequence, and AutoStore, on device power down. ...

... CC RECALL cycle will automatically be initiated and will take t to complete. HRECALL If the CY14E064L WRITE state at the end of power-up RECALL, the SRAM data will be corrupted. To help avoid this situation, a 10-Kohm resistor should be connected either between WE and system V Software STORE Data can be transferred from the SRAM to the nonvolatile memory by a software address sequence ...

... RECALL, or after a STORE, the WRITE will be inhibited until a negative transition detected. This protects against inadvertent writes during power-up or brown-out conditions. Noise Considerations The CY14E064L is a high-speed memory and so must have a high-frequency bypass capacitor of approximately 0.1 µF connected between V and V , using leads and traces that ...
