DLP® LightCrafter™ Display 160CP Evaluation Module 1

1 Evaluation Module Overview

1.1 Introduction

This user’s guide presents an overview of the DLP® LightCrafter™ Display 160CP evaluation module (EVM)

(DLPCLCR160CPEVM) and a general description of the main features and functions. The guide explains the

first steps to get started, and shows a detailed description of onboard LEDs, connectors, and overall EVM

assembly.

The EVM can be used by itself to display nHD (640x360) resolution graphics or images either generated by the

DLPC3421 display controller or the MSPM0G3507 MCU (microcontroller). Images can also be added from a

Micro-SD card through the MSPM0 MCU.

This guide provides the user with further information on how to successfully operate the EVM and get content

projected on the wall.

1.2 Kit Contents

The DLPDLCR160CPEVM is shipped as a fully assembled unit. The only component required to power up the

unit is a compatible power adapter (not included).

A 5 V power adapter with a 1 A minimum output and a USB-C connector is required.

1.3 DLPDLCR160CPEVM Subsystems

The DLP LightCrafter Display module consists of two subsystems:

•Formatter Board: includes the DLP chipset (DLPC3421 display controller and DLPA2005 PMIC/LED driver).

The MSPM0G3507 MCU, SSD1963 video interface driver, and Micro-SD card connector are also included.

•Light Engine: includes optics, RGB LEDs, and DLP160CP DMD displaying 640 × 360 pixels (nHD) on

screen.

The DLPDLCR160CPEVM is designed to operate at a maximum ambient temperature of 30°C. A block diagram

of the DLPDLCR160CPEVM is shown in Figure 1-1.

1.4 Device Information

•DLPC3421 (Figure 2-1): display controller controls the DLPA2005 (Figure 2-1) PMIC/RGB illumination driver

and the DLP160CP DMD (digital micromirror device).

•DLP160CP DMD is assembled with an Elephant optical module using SFM-03X-CG and SFM-03X-RAB

LEDs from Luminus with a brightness of 20L out of the box (the module is capable to deliver 50L, but requires

additional thermal designs for proper operation).

•MSPM0G3507 (Figure 2-1): MCU provides control application, nHD image generation through the SSD1963

(Figure 2-1), and UART (Universal Asynchronous Receiver/ Transmitter) (Figure 2-1) communication

programmable capabilities. The MCU can be programmed using ARM® SWD (Serial Wire Debug) interface

through the JTAG (Joint Test Action Group) connector (Figure 2-1).

•SSD1963 (Bridge IC) video interface driver gets 8080 commands from the MCU and outputs RGB666 parallel

interface signals to the DLPC3421 DLP display controller.

•DSI input (Figure 2-1): to the DLPC4321 controller provided through an external interface connector. Video

can be input through an external interface connector over the DSI interface. (Not tested)

•Power button (Figure 2-1) is used to gently power up and power down the DLP display system.

•Programmable push button (Figure 2-1) is used to provide user input controlled by the MCU.

•MicroSD card slot (Figure 2-1) is provided to add custom images controlled by the MCU (MicroSD card not

included).

•USB Type-C power supply interface (Figure 2-1) is used to power the EVM unit (USB Type-C cable and

power supply not included).

This DLP chipset is combined with illumination, projection optics, and RGB LEDs to create a projector that offers

brightness of approximately 20 lumens out of the box for image or informational video display in a very small

volume form factor.

The DLPDLCR160CPEVM is not a production design, and is intended for evaluation only.
