Description
The STM1403 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. STM1403 supports target levels 3 and lower.
The STM1403 includes 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 STM1403A also offers a V

The STM1403 is available in three versions, corresponding to three modes of the V
(supply voltage out), when the SAL (security alarm) is asserted (active-low) upon tamper
detection:
