SUMMARY DESCRIPTION
The STM1001 MICROPROCESSOR RESET Cir-
cuit is a low-power supervisory device used to
monitor power supplies. It performs a single func-
tion: asserting a reset signal whenever the VCC
supply voltage drops below a preset value and
keeping it asserted until VCC has risen above the
preset threshold for a minimum period of time
(trec).
