ADE3700
1 General Information
The ADE3700 family of devices is capable of implementing all of the advanced features of today’s
LCD monitor products. For maximum flexibility, an external microcontroller (MCU) is used for
controlling the ADE3700 and other monitor functions.

The ADE3700 architecture unburdens the MCU from all data-intensive pixel manipulations,
providing an optimal blend of features and code customizing without incurring the cost of a 16-bit
processor or memory. The key interactions between the monitor MCU and the ADE3700 can be
broken down into the features shown in the table below.

When power is first applied, the ADE3700 is asynchronously reset from a pin. GLBL

The MCU typically programs the ADE3700 with a number of default values

When the monitor has been powered on, the inputs can be monitored for

input or power down state.
