PRODUCTION DATA
A Pico projector is created by using a DLP chipset with a DLP230NP/NPSE (.23 1080p) digital micromirror device (DMD), a DLPC34x6 controller, a XC7Z020-1CLG484|4493 FPGA, and a DLPAxxxx PMIC/LED driver. The DLPC34x6 controller performs the digital image processing, the DLPA2000/2005/3000/3005 provides the needed analog functions for the projector, and the DLP230NP/NPSE DMD is the display device for producing the projected image.
In addition to the three DLP chips in the chipset, other chips are needed. At a minimum, a flash part is needed to store the DLPC34x6 controller software.
The illumination light that is applied to the DMD is typically from red, green, and blue LEDs. These are often contained in three separate packages, but sometimes more than one color of LED die may be in the same package to reduce the overall size of the Pico projector.
Power to the entire Pico projector can be controlled with 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 microamps of current on SYSPWR. When PROJ_ON is set low, the 1.8-V supply can remain at 1.8 V and used by other non-projector sections of the product. If PROJ_ON is low, the PMIC/LED driver does not draw current on the 1.8-V supply.
