STM1404
3V 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 (V
CC
switch output)
– Low when switched to V
CC
– High when switched to V
BAT
(BATT ON
indicator)
■
Battery low voltage detector (power-up)
■
Optional V
REF
(1.237V)
– (Available for STM1404A only)
■
Low battery supply current (5.3μA Typ)
■
Secure low profile 16-pin, 3x3mm, QFN
package
■
RoHS compliance
– Lead-free components compliant with the
RoHS directive
QFN16, 3x3mm (Q)

Normal mode: low when V
OUT
is internally switched to V
CC
and high when V
OUT
is internally switched to battery.
