1.2.1 Driver Board

The controller or illumination board shown in Figure 1-2 includes the DLP4620S-Q1 DMD, the DLPC231S-Q1 DMD Controller, and the TPS99000S-Q1. For the rest of the document, this board is interchangeably called the driver board and controller PCB. The driver board supports video inputs from either an HDMI™ or OpenLDI interface and provides the formatting and control to display the video on the DLP4620S-Q1 DMD. The EVM can be controlled with a USB-to-SPI port, which can also be used to reprogram the serial Flash that is used to store DLPC231S-Q1 software and configuration. The EVM has an external photodiode input that is used to control white point and brightness over a wide dimming range. A flex cable connects to the optical or light engine in this kit. This allows the driver board to communicate with the DMD found inside the optical or light engine. The driver board provides an interface for thermistors on the red, green and blue illuminator PCBs that can be used to monitor the temperatures of the illuminators.

The controller PCB contains the ports listed in Table 1-1. Indicator LEDs are listed in Table 1-2. Switches are defined inTable 1-3.

Table 1-1 Controller PCB Ports
Schematic Reference Function
J1 LED common anode (6-pin) - high current output up to 6A, locking and keyed connector
J2 Photodiode (3-pin)
J3 RGB LEDs and Thermistors (8-pin)
J4 OpenLDI (Flex connector)
J5 HDMI
J6 Header (6-pin): Texas Instruments internal use
J7 USB: Texas Instruments internal use
J8 USB-to-SPI (micro USB-B connector)
J9 DMD (Flex connector)
J10 12V Power input
Table 1-2 Controller LED Indicators
Schematic Reference Function
D5 (Red) HOST_IRQ

Off: Interrupt not asserted

On: Interrupt asserted
D6 (Green) PROJ_ON – Indicates PGU power has been turned ON
D7 (Green) 3.3V Power Good - input power to the driver board

Off: No power connected

On: Power connected
D30 (Green) LED0 System heartbeat
D31 (Blue) LED1 MCU Power Good

The controller PCB switches are listed in Table 1-3. SW2 is a toggle switch for PROJ_ON which is used to turn on and off the electronics. Note that parts of the board are still powered when PROJ_ON is in the off position. SW1, SW2 and SW3 are dip switches that control the states of configuration signals the DLPC230-Q1 reads when the device comes out of reset. These switches must be set based on the desired configuration options.

Table 1-3 Controller PCB Switches
Schematic Reference or Signal Number Function
SW1 HW/SW PROJ_ON Toggle Selection SwitchHW Mode: Toggle PROJ_ON using physical toggle switch (SW2)SW Mode: Toggle PROJ_ON using software commands
SW2

PGU Power (Toggle) - Turns on system when SW1 is set to HW control mode
SW3

HOLD_BOOTZ (DIP Switch)

ON: Low state - holds software in bootloader

Normal: High state - normal operation
SW4 Key0: Texas Instruments internal use
SW5 Key1: Texas Instruments internal use
SW6 Key2: Texas Instruments internal use
SW7 MCU Reset (momentary switch)
SW8 DMD Select: Set to DLP4620 -- Texas Instruments internal use
SW9 SPI download or command:

Set to OFF position - Texas Instruments internal use
