STM1404 3 V FIPS-140 security supervisor with battery switchover

The STM1404 family of security supervisors are a low power family of intrusion (tamper) detection chips targeted at manufacturers of POS terminals and other systems, to enable them to meet physical and/or environmental intrusion monitoring requirements as mandated by various standards, such as Federal Information Processing Standards (FIPS) Pub 140 entitled “Security Requirements for Cryptographic Modules,” published by the National Institute of Standards and Technology, U.S. Department of Commerce), EMVCo, ISO, ZKA, and VISA PED.

STM1404 will target the highest security level 4 and include both physical and environmental (voltage and temperature) monitoring.

The STM1404 include automatic battery switchover, RST output (open drain), manual (push-button) reset input (MR), power-fail comparator (PFI/PFO), physical and/or environmental tamper detect/security alarm, and battery low voltage detect features.

The STM1404A also offers a VREF (1.237V) as an option on pin 9. On STM1404B/C this pin is VTPU (internally switched VCC or VBAT).
