Non Volatile RAM (F-RAM & NVSRAM)

Anonymous
Not applicable

The block diagram on the front page of the STK11C68 datasheet shows the /HSB pin, but this pin is never mentioned anywhere else, or shown in the pinout. Is there or isn't there an /HSB pin?

   

Page 9 mentions AutoStore, but the document implies that the chip does not have the AutoStore feature. Does the chip have AutoStore or not?

   

Page 11 mentions 10 years or 10^5 cycles retention/endurance, but the table on page 5 mentions 100 years and 10^6 cycles. Which is it?

   

Thank you.

Q1. The block diagram on the front page of the STK11C68 datasheet shows the /HSB pin, but this pin is never mentioned anywhere else, or shown in the pinout. Is there or isn't there an /HSB pin?

   

A. HSB option is not available in this part.

   

Q2. Does the chip have AutoStore or not?

   

A. STK11C68 is a SoftStore nvSRAM and it doesn't have Autostore Operation. Data transfers under software control from SRAM to the nonvolatile elements (the STORE operation). Please refer to the datasheet in this link - http://www.cypress.com/?docID=15505

   

Q3. Page 11 mentions 10 years or 10^5 cycles retention/endurance, but the table on page 5 mentions 100 years and 10^6 cycles. Which is it?

   

A. In the datasheet link above, it tells only 1,000,000 STORE cycles & 100 year data retention.
