Product Description

The CM3132 provides an integrated power solution for a CPU core and DDR-I memory for consumer and other embedded applications. It features three independent linear regulators for VCORE, VDDQ and VTT supply regulation. The default voltage for VCORE is 1.5V. The SENSE_CORE pin can be tied to GND for the default voltage, or through a resistor divider for setting the CPU core in the range 1.2V to 1.8V. VDDQ is internally set to 2.50V and the VTT voltage is always half the VDDQ voltage. A capacitor should be connected to each of the three outputs.
