STM1403

SUMMARY 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 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. STM1403 supports target

levels 3 and lower

Pin Modes

OUT

The STM1403 is available in three versions, corre-

sponding to three modes of the V pin (Supply

Voltage Out), when the SAL (Security Alarm) is as-

serted (active-low) upon tamper detection:

The STM1403 includes Automatic Battery

Switchover, RST Output (Open Drain), Manual

(Push-button) Reset Input (MR), Power-fail Com-

parator (PFI/PFO), Physical and/or Environmental

Tamper Detect/Security Alarm, and Battery Low

Voltage Detect features.

is activated (may be used when V

is connected

OUT

directly to the V

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.

The STM1403A also offers a V

(1.237V) as an

REF

option on pin 9. On the STM1403B/C, this pin is

(internally switched V or V ).
