SMS2916

3 and 5 Volt Systems

Precision Voltage Supervisory Circuit

With Watchdog Timer and 16K I²C Memory

FEATURES

•

Precision Voltage Monitor

OVERVIEW

– Automatic V_CCSupply Monitor

- Complementary reset outputs for complex

microcontroller systems

TheSMS2916isapowersupervisorycircuitthatmonitors

V_CC(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
