A Pico projector can be created by using the DLP chipset that includes the DLP3310 (.33 1080p) DMD, 2xDLPC3437 controller, a XC7Z020-1CLG484I4493 FPGA, and DLPA300X PMIC/LED driver. The DLPC3437 and FPGA do the digital image processing, the DLPA300X PMIC provides the needed analog functions for the projector, and the DMD displays the projection.

In addition to the four DLP chips in the chipset, other chips can be needed. At a minimum, flash memories are needed to store the software and firmware to control the two DLPC3437s and the FPGA.

The illumination light that is applied to the DMD is typically from red, green, and blue LEDs. These LEDs are often contained in three separate packages, but sometimes more than one color of LED die can be in the same package to reduce the overall size of the pico-projector.

The entire pico-projector can be turned on and off by using a single signal called PROJ_ON. When PROJ_ON is high, the projector turns on and begins displaying images. When PROJ_ON is set low, the projector turns off and draws just microamps of current on SYSPWR. When PROJ_ON is set low, the 1.8-V supply can continue to be left at 1.8 V and used by other non-projector sections of the product. If PROJ_ON is low, the DLPA300X does not draw current on the 1.8-V supply.
