SUMMARY 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 phys-
ical and/or environmental intrusion monitoring
requirements as mandated by various standards,
such as Federal Information Processing Stan-
dards (FIPS) Pub 140 entitled “Security Require-
ments for Cryptographic Modules,” published by
the National Institute of Standards and Technolo-
gy, 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 (volt-
age and temperature) monitoring.
The STM1404 include Automatic Battery Switcho-
ver, RST Output (Open Drain), Manual (Push-but-
ton) 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).
VOUT Pin Modes
The STM1404 is available in three versions, corre-
sponding to three modes of the VOUT pin (Supply
Voltage Out), when the SAL (Security Alarm) is as-
serted (active-low) upon tamper detection:
STM1404A. VOUT stays ON (at VCC or VBAT)
when SAL is driven low (activated).
STM1404B. VOUT is set to High-Z when SAL is
driven low (activated).
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 Options) are pin-
compatible and available in a security-friendly, low
profile, 16-pin QFN package.
Figure 2. Logic Diagram
Note: 1. VREF only for STM1404A; VTPU for STM1404B/C.
2. Normal Mode: Low when VOUT is internally switched to
VCC and High when VOUT is internally switched to battery.
3. SAL, RST, PFO, and BLD are Open Drain.

Note: See PIN DESCRIPTIONS of the full datasheet for details.

VCC and High when VOUT is internally switched to battery.
2. SAL, RST, PFO, and BLD are Open Drain.
3. VREF only for STM1404A; VTPU for STM1404B/C.
