STM1404
3 V FIPS-140
security supervisor with battery switchover
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 factory-
programmed
■ 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 A typ)
■ Secure low profile 16-pin, 3 x 3 mm, QFN
package
■ RoHS compliance
– Lead-free components compliant with the
RoHS directive
QFN16, 3 mm x 3 mm (Q)

1.
Reset output, power-fail comparator, battery low detection (SAL, RST, PFO, and BLD are open drain).
2.
Normal mode: low when VOUT is internally switched to VCC and high when VOUT is internally switched to battery.
3.
Contact local ST sales office for availability.
4.
Pin 9 is the VREF pin for STM1404A. It is the VTPU pin for STM1404B/C.
