Power Reduction
AT89LP microcontrollers include two power-saving modes of operation: Idle and Power-
down. These modes can be exited through a variety of interrupt conditions.
The majority of embedded applications continue to be based on 8-bit devices. AT89LP
microcontrollers provide high levels of integration leading to reduced system cost, lower
power consumption, smaller packages, and faster time-to-market. These devices are ideal
for communications, consumer, and industrial products, ranging from battery-powered
devices to white goods. Some example uses include:
