S4242/S42WD42/S4261/S42WD61

Dual Voltage Supervisory Circuit

With Watchdog Timer(S42WD61) (S42WD42)

•

High Reliability

FEATURES

– Endurance: 100,000 erase/write cycles

– Data retention: 100 years

•

Precision Dual Voltage Monitor

– V_CCSupply Monitor

- Dual reset outputs for complex

microcontroller systems

- Integrated memory write lockout function

- No external components required

OVERVIEW

The S42xxx are a precision power supervisory circuit. It

automatically monitors the device’s V_CClevel and will

generatearesetoutputontwocomplementaryopendrain

outputs.InadditiontotheV_CCmonitoring,theS42xxxalso

provides a second voltage comparator input. This input

has an independent open drain output that can be wire-

OR’ed with the RESET I/O or it can be used as a system

interrupt.

•

Second Voltage Monitor Output

– Separate V_LOWoutput

– Generates interrupt to MCU

– Generates RESET for dual supply systems

- Guaranteed output assertion to V_CC- 1V

Watchdog Timer (S42WD42, S42WD61)

– 1.6s

The S42xxx also has an integrated 4k/16k-bit nonvolatile

•

Memory Internally Organized 2 x8

memory. The memory conforms to the industry standard

two-wire serial interface. In addition to the reset circuitry,

the S42WD42/S42WD61 also has a watchdog timer.
