ZPSD
Background
Portable and battery-powered systems have recently become major embedded control
application segments. As a result, the demand for electronic components having extremely
low power consumption has increased dramatically. Recognizing this trend, WSI, Inc.
developed a new lower power PSD part, denoted ZPSD211R. The Z stands for Zero-power
because ZPSD products virtually eliminate the DC component of power consumption,
reducing it to standby levels. Virtual elimination of the DC component is the basis for the
words “Zero-power” in the ZPSD name. ZPSD products also minimize the AC power
component when the chip is changing states. The result is a programmable microcontroller
peripheral family that replaces discrete circuit components, while drawing less power.
