INTRODUCTION
The SMR100 programmable reset controller is
designed for consumer applications specified by
Satellite-TV set-top box standards. The SMR100
provides a satellite box controller solution during initial
setup, changing programming cards and/or system
reset needs without removing power. The part can
accommodate a long-delay hold down of an external
reset push-button using an internal programmable de-
bounced timer.
however, multiplexed programming pins are also
provided for in-system programming for prototype
purposes.
The required hold down time is programmable from
0.325 to 40 Sec with an internal on-chip oscillator.
Accurate warning of a 3.1V brownout condition
(BAD_PWR#),
(RESET_OUT#) timeout period when the VDD supply
pin reaches 3.0V are also provided. During a reset
(RESET_OUT#), the part enables the “BAD_PWR#” or
brownout warning output until the reset has cleared. A
programmable glitch filter avoids nuisance tripping of
the internal comparators.

... VDD pin provides additional transient immunity. Since the BAD_PWR# and RESET_OUT# outputs are open drain, the device interfaces easily with µPs that have bidirectional-reset pins. Connecting the RESET_OUT# output directly to the µP’s RESET pin allows either the µP or the SMR100 to assert a reset. T RESET_HD 2076 1.6 06/30/04 ...
