DLP5534PROJQ1EVM Evaluation Module User's Guide
The DLP5534PROJQ1 Evaluation Module (EVM) is a complete electronic and optical 405 nm projector
utilizing the DLP5534-Q1 chipset. The DLP5534-Q1 chipset consists of the DLP5534-Q1, the DLPC230Q1, and the TPS99000-Q1. Electronics with the DLP5534-Q1 chipset is combined with illumination and
projection optics and a 405 nm LED to make an automotive grade projector for applications such as
transparent window display utilizing phosphor film(s) embedded in a window.
The DLP5534PROJQ1 EVM is not a production design. It is intended for evaluation only.

User Guide Overview
This user's guide presents an overview and general description of the DLP5534PROJQ1 EVM and
provides first steps for getting started using the EVM.
1.1
What is in the DLP5534PROJQ1 EVM
The DLP5534PROJQ1 EVM integrates the contents of the DLP5534Q1 electronics EVM with 405 nm
illumination and projection optics to produce a complete projector shown in Figure 1. The projector utilizes
a Luminus CBM-25X-UV 405 nm LED to produce a very bright 405 nm projector. A heatsink and fans are
provided for cooling of the LED and electronics.
Figure 1. DLP5534PROJQ1EVM Projector
The DLP5534Q1 electronics EVM that is integrated into the projector 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 DLP5534-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 DLP5534-Q1 DMD. The EVM can be
controlled with either an SPI or 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 includes a flex interface to control the Illumination
Driver PCB. The EVM has external photodiode inputs and thermistor inputs which are not used for this
application.

Illumination Driver PCB
The Illumination Driver PCB shown in Figure 3 is controlled by the Controller PCB over a flex cable.
Power can be input to the Illumination Driver from a lab supply. The Illumination driver provides reverse
bias protection and supplies power to the Controller PCB over a separate cable. The Illumination Driver
has outputs for one to three illuminators. These are typically LEDs, but it is possible other illuminators
could be used. See Section 1.2.2 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!

Input Video Specifications
The following input video resolutions are supported on the HDMI and OpenLDI interfaces. These input
video resolutions are programmed in the Extended Display Identification Data (EDID) EEPROM for the
EVM's HDMI interface allowing a connected computer to read the supported resolutions and timing. Note
that some computers may not be able to output all of these resolutions, in particular 576 × 288.
• 1152 × 1152
• 1152 × 576
• 576 × 288
The recommended input source timings for the EVM's HDMI interface are specified in the DLPC230-Q1
data sheet. These timing parameters are also recommended for the OpenLDI interface.

2.5
Steps to Reprogram the Onboard Flash Memory
The DLP5534PROJQ1 EVM 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.
