SUMMARY DESCRIPTION
STM1403/4 family security supervisors power family intrusion (tamper) detection chips targeted manufacturers terminals other systems, enable them meet physical and/or environmental intrusion monitoring requirements mandated various standards, such Federal Information Processing Standards (FIPS) entitled "Security Requirements Cryptographic Modules," published National Institute Standards Technology, U.S. Department Commerce), EMVCo, ISO, ZKA, VISA PED. STM1404 will target highest security level include both physical environmental (voltage temperature) monitoring, while STM1403 will 100% pin-compatible, functional subset STM1404, target levels lower, includes functionality STM1404, except over/under temperature monitoring. STM1403 STM1404 include Automatic Battery Switchover, Output (Open Drain), Manual (Push-button) Reset Input (MR), Powerfail Comparator (PFI/PFO), Physical and/or Environmental Tamper Detect/Security Alarm, Battery Voltage Detect features. Figure Logic Diagram STM1404A STM1403A also offer VREF (1.237V) option STM1403B/C STM1404B/C this VTPU (internally switched VBAT). VOUT Modes Either part type made available three versions, corresponding three modes VOUT (Supply Voltage Out), when (Security Alarm) asserted (active-low) upon tamper detection: STM1403A, STM1404A. VOUT stays VBAT) when driven (activated). STM1403B STM1404B. VOUT HighZ when driven (activated). STM1403C STM1404C. VOUT driven Ground when activated (may used when VOUT connected directly external SRAM that holds cryptographic codes). variants (see Table Device Options) pincompatible available security-friendly, profile, 16-pin package.

TAMPER DETECTION
Physical There four high-impedance physical tamper detect input pins, normally High (NH) normally (NL). Each input designed with glitch immunity. These inputs connected externally several types actuator devices (e.g., switches, wire mesh). tamper four inputs that causes state change will trigger security alarm (SAL) drive active-low. Once tamper condition longer exists, will return normal High state. Normally High (NH). They connected externally through closed switch high-impedance resistor VOUT case STM1403/4A STM1404A) VTPU case STM1403B/C, STM1404B/C), tamper condition will detected when input pulled low. used, VOUT VTPU. Normally (NL). They connected externally through high-impedance resistor closed switch VSS. tamper condition will detected when input pulled high. used, VSS. Supply Voltage internally switched supply voltage, VINT (either input VBAT input) continuously monitored. VINT should exceed over voltage trip point, (set 4.2V, typical), should below under voltage trip point, (set 2.0v, typical). will driven active-low. Once tamper condition longer exists, will return normal High state. Temperature (STM1404 Only) STM1404 built-in, bandgap-based sensor monitor temperature. preset (customer-selectable, factory-programmed) overtemperature trip point (TH) under-temperature trip point (TL) exceeded, asserted low. When tamper condition exists, normally High (see DESCRIPTIONS, page full datasheet details). When tamper detected, activated (driven low), independent part type. VOUT driven three states, depending which variant STM1403 STM1404 being used (see Device Options, page High-Z; Ground (VSS). Note: STM1403 STM1404 must initially powered above VRST enable tamper detection alarms. example, battery while alarm condition detected until rises above VRST (and trec expires). From this point alarms detected either battery VCC. This done avoid false alarms when device goes from power operational state.
