The STM1403/1404 is a family of low power intrusion (tamper) detection security supervisors for the Point of Sale (POS) terminal market. They enable manufacturers to meet security standards such as FIPS-140 (NIST, US Dept. of Commerce), EMV Co, ISO, ZKA (Germany) and Visa PED. Until recently, many of these intrusion detection functions were implemented by using several discrete devices. The STM1403/1404 integrates all these functions into a small profile security-friendly QFN package. The STM1403/1404 meets most price, performance and board space objectives while ensuring customers are able to meet current and future security certification requirements for physical and environmental tamper detection.
