Description
STM1404
1
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.
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).
1.1
VOUT pin modes
The STM1404 is available in three versions, corresponding to three modes of the VOUT pin
(supply voltage out), when the SAL (security alarm) is asserted (active-low) upon tamper
detection:
1.1.1
STM1404A
VOUT stays ON (at VCC or VBAT) when SAL is driven low (activated).
1.1.2
STM1404B
VOUT is set to High-Z when SAL is driven low (activated).
1.1.3
STM1404C
VOUT is driven to ground when SAL is activated (may be used when VOUT is connected
directly to the VCC pin of the external SRAM that holds the cryptographic codes).
All variants (see Table 1: Device summary) are pin-compatible and available in a security-
friendly, low profile, 16-pin QFN package.
