SMS2916  
3 and 5 Volt Systems  
Precision Voltage Supervisory Circuit  
With Watchdog Timer and 16K I2C Memory  
FEATURES  
Precision Voltage Monitor  
OVERVIEW  
– Automatic VCC Supply Monitor  
- Complementary reset outputs for complex  
microcontroller systems  
TheSMS2916isapowersupervisorycircuitthatmonitors  
VCC (eitherina5Vsystemor3Vsystem)andwillgenerate  
complementary reset outputs. The reset pins also act as  
I/Os and may be used for signal conditioning. The  
SMS2916 also has an on-board watchdog timer that has  
a nominal time out period of 1.6 seconds.  
- Integrated memory write lockout function  
- No external components required  
Watchdog Timer  
– Nominal 1.6 second Timeout  
Memory Internally Organized 2K X 8  
– Two Wire Serial Interface (I2C™)  
High Reliability  
The SMS2916 integrates a 16K-bit nonvolatile serial  
memory. It features the industry standard I2C serial  
interface allowing quick implementation in an end-users’  
system.  
– Endurance: 1,000,000 erase/write cycles  
– Data retention: 100 years
