1 DLP3021-Q1 Electronics EVM Overview
This user's guide presents an overview of the DLP3021-Q1 electronics EVM, a general description of the
main features and functions, and quick start procedure for out-of-box evaluation. TI recommends users to first
read the
Dynamic Ground Projection Application Requirements ( DLPA116 ) and DLP3021-Q1 Dynamic Ground
Projection System Design ( DLPA086 ) reports to become familiar with the terminology, variables, application
considerations, and system design requirements for dynamic ground projection as they relate to the DLP3021-
Q1 chipset.
1.1 Introduction
The DLP3021LEQ1EVM Evaluation Module (EVM) is a complete electronic and optical subsystem designed
to control and interface with the DLP3021-Q1 chipset. The DLP3021-Q1 interfaces with an FPGA based DMD
controller. This chipset is combined with illumination and projection optics, and RGB LEDs to create a projector
that offers brightness of up to 30 lumens with full motion video playback in a small volume form factor. The
DLP3021LEQ1EVM is not a production design, and is intended for evaluation only.
1.2 What is in the DLP3021-Q1 Light Engine EVM
The DLP3021-Q1 Light Engine EVM consists of three subsystems and two boards:
• DLP3021LEQ1EVM board:
– Formatter — Includes the DLP3021-Q1 DMD, FPGA based DMD controller, the MSP430G2553 MCU,
external flash memory, and the TPS65100-Q1 PMIC.
– Illumination Driver — Includes illumination drivers and FETs.
– Light Engine — Compact light engine designed to display images from the formatter.
• FTDI C232HM-DDHSL-0 USB to MPSSE serial cable for 3.3V logical level SPI communication with the
FPGA based DMD controller and external flash memory. The Cheetah™ USB-to-SPI interface can be used
as a faster alternative for USB-to-SPI communication, but must be purchased separately.
• SPI Adapter board — intermediate board between the FTDI USB-to-SPI cable and DLP3021LEQ1EVM
electronics board required for Host Mute and Flash Programming operating modes. Includes toggle switches
to change the operating mode of the EVM.
