Outline
May 21, 2009
In various CPU systems or other logic systems, when the time of a power supply injection and a power supply are
severed for a moment, this IC detects supply voltage and applies reset to a system.
To ±1.5% of detection voltage accuracy of the conventional product, a maximum of ±0.5% of super-high precision
is realized, and it is more suitable for battery detection etc. The accuracy from elegance is conventionally raised from
+100/-50% to ±10% also about delay resistance.
Moreover, the component-side product is realizing the small space using SSON-4.

In a single-chip computer, writing 1 clears it to 0, and writing 0 clears it to 0. What is the difference?
In the microcontroller documentation, the registers are generally of type rw, and some are r or w. For some special registers, the setting of 1 is automatically implemented by hardware, such as the fl...
