Description

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.

Features

■ STM1404 supports FIPS-140 security level 4

– Four high-impedance physical tamper inputs

– Over/under operating voltage detector

– Security alarm (SAL) on tamper detection

– Over/under operating temperature detector

– Over/under temperature thresholds are customer-selectable and factoryprogrammed

■ Supervisory functions

– Automatic battery switchover

– RST output (open drain)

– Manual (push-button) reset input (MR)

– Power-fail comparator (PFI/PFO)

■ Vccsw (VCC switch output)

– Low when switched to VCC

– High when switched to VBAT (BATT ON indicator)

■ Battery low voltage detector (power-up)

■ Optional VREF (1.237 V)

– (Available for STM1404A only)

■ Low battery supply current (5.3 μA typ)

■ Secure low profile 16-pin, 3 x 3 mm, QFN package

■ RoHS compliance

– Lead-free components compliant with the RoHS directive
