OVERVIEW
The S24042 and S24043 are power supervisory devices
with 4,096 bits of serial E
2
PROM. They are fabricated
using SUMMIT’s advanced CMOS E
2
PROM technology
and are suitable for both 3 and 5 volt systems.
The memory is internally organized as 512 x 8. It features
the I
2
C serial interface and software protocol allowing
operation on a simple two-wire bus.
The S24042 provides a precision V
CC
sense circuit and
two open drain outputs: one (RESET) drives high and the
other (RESET#) drives low whenever V
CC
falls below
V
TRIP
. The S24043 is identical to the S24042 with the
exception being RESET is not bonded out on pin 7.
