The SMR101 is a programmable reset controller
especially
designed
for
electronics. The device provides dual outputs that can
be used to implement “soft” and “hard” system resets.
Both resets can be triggered by an external reset input,
and an internal voltage monitor can trigger the soft
reset. Typically a “soft” reset applies to volatile registers
in an embedded controller while a hard reset is
equivalent to a full power cycle without the associated
power-up delays. The SMR101 receives an external
push-button input using an internal programmable de-
bounced timer. The push button input hold down time is
programmable up to 40 seconds with an internal on-chip
timer. A “short” hold down time (0.125-10 sec) asserts
the SOFT_RST# pin while a long hold down time (0.5-
40 sec) asserts the HARD_RST# pin. Both reset
outputs have programmable output durations from 1-
200ms. Additionally, voltage monitoring is provided via a
programmable threshold detector (2.30V – 4.50V) on
the VDD pin. This voltage detector asserts the
SOFT_RST# pin for the same 1-200ms output duration
as above. A 15us glitch filter avoids nuisance tripping
that can result in unnecessary system resets. The
SMR101 is factory programmed, to default values;
however, multiplexed programming pins are also
provided for in-system programming for prototype
purposes.
