It automatically monitors the device’s VCC level and will generate a reset output on two complementary open drain outputs. In addition to the VCC monitoring, the S42xxx also 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. The S42xxx also has an integrated 4k/16k-bit nonvolatile 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.
