T he ADM1232 is a superior, pin-compatible upgrade for the
MAX 1232 and the DS1232L P and DS1232. T he Analog
Devices ADM1232 is a microprocessor monitoring circuit that
can monitor:
1. Microprocessor Supply Voltage.
2. Whether a Microprocessor has locked-up.
3. An External Interrupt.
T he ADM1232 is available in four different packages:
1. T he ADM1232ARM in an 8-lead microSOIC (RM-8).
2. T he ADM1232AN in an 8-lead PDIP (N-8).
3. T he ADM1232ARW in a 16-lead wide SOIC (R-16).
4. T he ADM1232ARN is an 8-lead narrow SOIC (R-8).
