DLP5530Q1EVM Evaluation Module User's Guide
The DLP5530Q1EVM Evaluation Module (EVM) is a complete electronic subsystem designed to control
the DLP5530-Q1 chipset. The DLP5530-Q1 chipset consists of the DLP5530-Q1, the DLPC230-Q1, and
the TPS99000-Q1. When combined with illumination and projection optics, RGB LEDs and a photodiode,
this EVM can be used to develop an automotive grade projector for applications such as augmented
reality head-up display (AR HUD) or interior projection systems.
Except for the DMD, there are no optical elements provided with this EVM. It is expected that this EVM is
procured in order to mount to a custom designed picture generation unit (PGU) or projector.
The DLP5530Q1EVM is not a production design. It is intended for evaluation only.

The DLP5530Q1EVM electronics EVM pairs with 3 different optical module configurations, all available as
standalone EVMs. The different options are listed below in Table 1.

1 User Guide Overview
This user's guide presents an overview and general description of the DLP5530Q1EVM and provides first
steps for getting started using the EVM.
1.1 What is in the DLP5530Q1EVM EVM
The DLP5530Q1EVM consists of a controller PCB, an illumination driver PCB, cables, and a USB to SPI
adapter.
1.1.1 Controller PCB
The controller PCB shown in Figure 2 includes the DLP5530-Q1 DMD, the DLPC230-Q1 DMD Controller,
and the TPS99000-Q1. It supports video inputs from either a micro HDMI or OpenLDI interface and
provides the formatting and control to display the video on the DLP5530-Q1 DMD. The EVM can be
controlled with either a SPI or an I2C interface. The SPI or I2C interface can also be used to reprogram the
serial Flash that is used to store DLPC230-Q1 software and configuration. An optional second SPI port is
provided for monitoring the TPS99000-Q1. The EVM has an external photodiode input that is used to
control white point and brightness over a wide dimming range. An optional second photodiode input is also
provided. The EVM includes a flex interface to control and monitor the illumination driver PCB. It also
provides an optional interface for thermistors on the red, green and blue illuminator PCBs that can be
used to monitor the temperatures of the illuminators.
Figure 2. DLP5530Q1EVM Controller PCB
The controller PCB contains the ports listed in Table 2. Indicator LEDs are listed in Table 3.

1.1.2 Illumination Driver PCB
The illumination driver PCB shown in Figure 3 is controlled and monitored by the controller PCB over a
flex cable. Power can be input to the illumination driver from a bench top supply. The illumination driver
provides reverse bias protection and supplies power to the controller PCB over a separate cable. The
illumination driver PCB regulates the input power to 6.5 V or 8 V prior to the illumination driver circuitry.
The illumination driver has outputs for red, green and blue illuminators. These are typically LEDs, but it is
possible other illuminators could be used. See Section 1.2.1 for input and output specifications of the
EVM. Depending on operating conditions, some parts and surfaces of the PCB can be hot.
CAUTION
Hot surface. Contact may cause burns. Do not touch!

The illumination driver PCB contains the ports listed in Table 5.

2.2 Software Installation
1. Download and install the DLPC230-Q1 Control Program Lite from ti.com.
2. Install Total Phase Cheetah USB adapter drivers from the Total Phase website.
2.3 Powering-Up EVM
1. Connect input power cable to a power supply that meets input power specifications defined in Table 8.
The red wire is the V+ terminal and black wire is the V– terminal.
2. Turn on the supply power. Once powered up, a controller PCB LED indicator (D4) should illuminate
green.
3. Turn the PROJ_ON switch (SW4) ON. The ON position is away from the board, and OFF is toward the
board. A controller PCB LED indicator (D5) should illuminate green.
2.4 Connecting EVM to the DLPC230-Q1 Control Program
1. Start the DLPC230-Q1 Control Program Lite.
2. On the connection page set the DLPC230-Q1 Host to SPI and select the Cheetah from the drop down
menu (see Figure 6). Note, the Cheetah must be connected to computer with USB cable for it to show
up in the drop down box.

3. Select "Connection Settings" to confirm the SPI configuration shown in Figure 7 matches the controller
PCB switch settings described in Table 4. Specifically, SPI mode and CRC/Checksum may vary based
on switch settings. Press "OK" once configuration is complete.
Figure 7. DLPC230-Q1 Automotive Control Program Communication Settings
4. Click the Connect button. The green circle next to the Connect button should then light up to indicate
that connection was successful to the Cheetah Adapter.
2.5 Steps to Reprogram the Onboard Flash Memory
The DLP5530Q1EVM comes with onboard serial Flash that is pre-programed with software and basic
configuration. The software and configuration can be updated by reprogramming the serial Flash with the
DLPC230-Q1 Automotive Control Program. Steps to re-program the serial Flash are listed below.
1. Using the DLPC230-Q1 Automotive Control Program, which is connected to the EVM, navigate to the
"Flash Program" tab.
2. Using the folder icon, select an Image File (.bin) and open it.
3. Click "Program and Verify Flash Memory."
Note that if the device is in Display mode, it will automatically be switched to Standby during programming.
3 Optical Engine Requirements
The DLP5530Q1EVM can be coupled to an optical engine (not included) to implement a head-up display
function or an automotive interior projection system. The detailed requirements of the optical engine are
beyond the scope of this document, but the optical engine should have separate red, green and blue
illuminators. These are typically LEDs. The optical engine will also need to provide a photodiode in the
illumination path before the DLP5530-Q1 DMD. The photodiode is used to control white point and
brightness output. A heatsink for the DLP5530-Q1 DMD might be needed for operation in high
temperature ambient environments, but is not included in the DLP5530-Q1 Electronics EVM.

WARNING
When choosing your LED component (not included with this EVM)
the end user must consult the LED data sheet supplied by the LED
manufacturer to identify the EN62471 Risk Group Rating and
review any potential eye hazards associated with the LED chosen.
Always consider and implement the use of effective light filtering
and darkening protective eyewear and be fully aware of
surrounding laboratory-type set-ups when viewing intense light
sources that may be required to minimize or eliminate such risks in
order to avoid accidents related to temporary blindness.
