25 / 63 page  7 Detailed Description 7.1 Overview The DLPC3420 part is a display controller for the DLP160AP (0.16 QnHD) DMD. The DLPC3420 controller is part of the chipset composed of the controller, DLP160AP (0.16 QnHD) DMD, and DLPAxxxx PMIC (which includes an LED driver). To ensure reliable operation of the DLP chipset, the DLPC34xx must always be used with the supported devices shown in Table 6-1. The DLPC34xx display controller provides interfaces along with data and image processing functions that are optimized for small form factor and power-constrained display applications. Applications include projection within mobile projectors, smart displays, smartphones, tablets, augmented reality glasses, mobile accessories, smart home displays, and Pico projectors. The DLPC3420 is not a front-end processor; therefore, standalone projectors must include a separate front-end chip to interface to the outside world (for example, a video decoder, HDMI receiver, or USB I/F chip). 7.2 Functional Block Diagram Input Control Processing Test Pattern Generator Splash Screen /20 /5 /24 Parallel Video or BT656 Port Arm ® Cortex®-M3 Processor 128 KB I/D Memory JTAG I2C_0 SPI_0 GPIO SPI_1 I2C_1 LED Control Other options eDRAM (Frame Memory) Real Time Control System Clocks and Reset Generation DLP Subsystem Display Formatting DMD Interface Video Processing x Brightness Enhancement x Chroma Interpolation x Color Space Conversion x Color Correction x CAIC Processing x Contrast Adjustment x Gamma Correction x Image Format Processing x Power Saving Operations Clock (Crystal) Reset Control DMD_HS_CLK(sub-LVDS) DMD_HS_DATA(A:H)(sub-LVDS) DMD_LS_CLK DMD_LS_WDATA DMD_LS_RDATA DMD_DEN_ARSTZ / / / / www.ti.com DLPC3420 DLPS232 – OCTOBER 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 25 Product Folder Links: DLPC3420 |
