1 DLPC7540EVM, DLP471TEEVM, and DLP650TEEVM Overview
1.1 Welcome
The DLP Products DLPC7540EVM, DLP471TEEVM and DPL650TEEVM evaluation modules (EVMs) offer a
reference design to enable faster development cycles for users of the DLPC7540 chips and allow evaluation of
TI’s DLP471TE and DLP650TE UHD chipsets. These consist of one controller EVM (DLPC7540EVM) and two
DMD EVMs (DLP471TEEVM and DLP650TEEVM).
These evaluation kits bring together a set of components providing a great starting point to evaluate a UHD DLP
system for:
• Laser TV
• Enterprise Projectors
• Digital Signage
• Gaming Machines
• Smart Projectors
• Stage Lighting Systems
1.2 What is in the DLP471TEEVM, DLP650TEEVM, and DLPC7540EVM Evaluation Modules?
The DLP471TEEVM, DLP650TEEVM and DLPC7540EVM are designed to be used in pairs. The DMD EVMs
cannot be operated without the Controller EVM, DLPC7540EVM.
The DLP471TEEVM, which includes the DLP471TE display chip, and the DLP650TEEVM, which includes the
DLP650TE display chip, include the two flex cables required to connect to the DLPC7540EVM. DLPC7540EVM
includes all circuitry required to drive the DLP471TE and DLP650TE display chips.
The DLPC7540EVM which consists of a formatter board (Figure 1-1) and an HDMI input processing front-end
board (Figure 1-2), includes a DLPC7540 controller, three DLPA100s which serve as the power management
and motor drivers, and other system circuitry such as the Vx1 interface front-end and system fan control.
The DLPC7540EVM can be programmed with either the DLP471TE or DLP650TE firmware which is available on
the DLPC7540 product page. This firmware allows the DLPC7540EVM to drive either display chip. Figure 1-1,
Figure 1-2, and Figure 1-3 show the top side of all boards making up the EVMs.
Note
Figure 1-1, Figure 1-2, and Figure 1-3 do not show the necessary flex cables needed to pair to
DLPC7540EVM.

1.4 Other Items Needed for Operation
The DLP471TEEVM, DLP650TEEVM, and the DLPC7540EVM are evaluation modules (EVM) that are capable
of displaying images on to the DMD. However, these EVMs do not ship with optics, illumination source, cables,
power supplies, or additional hardware components. These are system parameters that are left for the user to
design, the EVMs are meant to accelerate initial system design.
• Power supply - Required for EVM operation (See Section 4.1)
• Micro-USB cable: A to Micro B USB cable - Required for GUI interface
• Optics
• Illumination module and source
• XPR actuator
The firmware provided on ti.com is for the sole purpose of operating the electronic components that make up the
DLP471TEEVM, DLP650TEEVM, and the DLPC7540EVM evaluation modules. Any additions made to the EVMs
such as illumination, optics, actuator, and so on will require contacting Texas Instruments for additional support
in including these elements specific to customer application.
1.5 DLPC7540EVM, DLP471TEEVM, and DLP650TEEVM EVM Flex Cable
Electrical malfunctions can occur by stressing the flex cable(s) connecting the DMD circuit board to the
DLPC7540EVM formatter board. Stressing the flex cable can be caused by:
• Bending sharply the flex cable(s).
• Repeatedly bending the flex cable(s).
• Excessive insertion and extraction of flex cables to/from board connectors.
Note
Minimize any handling/movement on the flex cables during operation

2 Quick Start
This chapter offers a quick start guide on how to connect the DLP471TEEVM or DLP650TEEVM to the
DLPC7540EVM, how to power up the DLPC7540EVM, and how to program the DLPC7540EVM to display a
SPLASH image on the DMD.
2.1 Downloading the Software
Before programming the DLPC7540EVM, ensure the DLPDLC-GUI and DMD firmware are both downloaded
on the PC. The DLPDLC-GUI will allow for operation of the EVM. The DMD firmware is required so the
DLPC7540EVM knows which DMD is being controlled. The DLP471TEEVM comes with a DLP471TE DMD
which is for 4K display applications. The EVM when installed with DLP471TE DMD can operate using
DLP471TE (4K) or DLP471NE (1080p) based firmware. Similarly, the DLP650TEEVM comes with a DLP650TE
DMD for 4K display applications and can operate with DLP650TE (4K) or DLP471NE (1080p) based firmware.
Any of the two types of DMD EVMs can also be retrofitted with their corresponding 1080p DMDs (DLP471NE/
DLP651NE) but will not have XPR operation enabled. See Table 2-1 for summary of firmware compatibility.

1. The DMD supporting firmware and DLPDLC-GUI can be found in the EVM tool folder and in the product
pages on TI.com. These are the product pages for the DLP471TE, DLP471NE, DLP650TE, DLP651NE, and
the DLPC7540.
2. XPR operation which is required for 4K resolution is disabled.
2.2 Connecting the DLP471TEEVM, or DLP650TEEVM, to the DLPC7540EVM
Before connecting the DLP471TEEVM/DLP650TEEVM to the DLPC7540EVM, locate the two flex cables that
are packaged with the DLP471TEEVM/DLP650TEEVM. Ensure the flex cables are not torn or damaged before
connecting the DMD EVMs or the DLPC7540EVM.
The flex cables are exactly the same, meaning there is not a right or left cable. The cables are interchangeable.
Connect the DLP471TEEVM or DLP650TEEVM to the DLPC7540EVM formatter board by connecting the two
flex cables matching the board connectors as listed in Table 2-2.

2.3 Powering-up the DLPC7540EVM and Preparing to Program the DLPC7540EVM
There's only one jumper that is included with the DLPC7540EVM. This jumper is installed on J67 during normal
operation between formatter and front-end boards. Before powering up the EVM for programming, ensure the
included jumper is installed on J9 instead. The jumper locations are listed in Section 3.1.
Table 2-3. Reference Designators
Jumper Description (Bold Indicates Default Position)
J67 - Front End 5 V Uninstalled - 5 V not supplied to J3
Installed - Formatter board provides 5 V to Front-end board over J3 connection
J9 - Hold in Boot Loader Uninstalled - Normal Operation
Installed - Hold in Boot Loader
Jumper J9 is the Hold BL jumper. This jumper is used to put the DLPC7540EVM into boot loader mode, which
allows the DLPC7540 controller to be programmed. Connect this jumper to prepare the DLPC7540EVM to be
programmed.
To power up the DLPC7540EVM, a 12-V, 5-A power supply is needed. Ensure the power supply is functional and
the switch SW5 and SW1 on the formatter board are set to off before connecting the power supply to the EVM.
Connecting the power supply when the switch is in the off position may prevent damage to the DLPC7540EVM
from poor power connections. The image below shows SW5 and SW1 and their operating positions.

Figure 2-2. ON/OFF Switches
Once the power supply has been connected to the DLPC7540EVM, the switches SW5 and SW1 in that order
can be flipped to the on position. You can then plug in the USB cable to J2 of the board to prepare for
programming the board. Verify that D5, D6, D7 and D15 LEDs are on.
2.4 Programming the DLPC7540EVM and Displaying a SPLASH Image
Follow these steps in order to download and configure the DLPDLC-GUI for DLPC7540 operation:
1. Download the DLPDLC-GUI and the Firmware SW package that includes the Firmware binary (.img) files for
DLP471TE and DLP650TE.
2. Install and open the DLPDLC-GUI
3. Setting up Communication Preferences:
a. DLPDLC-GUI supports USB and I2C communication. To change these settings in GUI, please go to
Debug screen and select Connection tab.
b. For USB, please select the USB interface and click Connect Figure 2-3. Note: USB is the preferred
interface to download the firmware flash image to the EVM as it is much faster than I2C and won't
require any additional hardware.

c. Verify that EVM Status shown at bottom left of GUI says Connected, Bootloader Mode indicating you are
ready to load image file into EVM.
4. Flash Loader Configuration:
a. Go to Firmware screen, select Update Firmware tab. Click on the folder icon to browse for the applicable
firmware depending on the actual DMD that is connected to DLPC7540EVM. Once firmware image file is
selected, click on Start Update Figure 2-4.
b. Wait for the programming progress to indicate that firmware update is complete.
c. Turn off the EVM by toggling the SW1 and SW5 switches in that order to off position. Remove the
jumper from J9 and install it back to J67.
d. Turn on the EVM by toggling the SW5 and SW1 switches in that order to on position. After about 3
seconds you should see D5, D6, and D7 LEDs steadily on and D15 LED flashing. The DLP Texas
Instruments logo should be visible on the DMD Figure 2-5.
