The DS3600 is a secure supervisor with 64 bytes of SRAM for applications requiring the secure storage of encryption keys, including POS terminals. The DS3600 supports the highest security level of the FIPS 140-2, Common Criteria, PCI-PED, and EMV 4.1 certification entities. The 64B key memory is constantly complemented in the background to prevent oxide stress and memory imprinting. In the event of a qualified tamper event, the key memory is rapidly cleared and a negative bias is applied to clear SRAM external to the DS3600.
