The DLP® products DLP2021AM263Q1EVM evaluation module (EVM) is an electronic-only system designed to enable accelerated evaluation of the DLP2021-Q1 chipset. The DLP2021-Q1 digital micromirror device (DMD) interfaces with a Sitara MCU-based DMD controller to enable a graphics processing unit (GPU) free system architecture. The 4bit-wide eMMC flash interface of the Sitara MCU allows for fast memory reads to support 25fps playback, and fast writes to enable on-the-fly re-programming of image and video content. Daughtercard sockets on this EVM enable automotive- and industrial-centric interfaces such as 10BASE-T1S Ethernet or CAN-FD. This EVM is compatible with white and RGB LED illumination sources. The DLP2021LEQ1EVM is not a production design and is intended for evaluation only.
Features
- Sitara MCU's Programmable Realtime Unit (PRU) repurposed as a direct drive interface to emulate the DMD's DDR2 timing specification.
- eMMC flash memory used to store uncompressed bitplane and DMD control signal data to fully offload the Sitara MCU from having to perform any additional processing or manipulation of the bitplane data.
- Single LED driver available to support white or RGB LED illumination sources.
- DMD interposer and mounting holes allow the DLP2021LEWQ1EVM optical light engine to be attached to create a fully operational projector system.
- Though SPI is the primary host interface, Ethernet, CAN, UART, I2C and LIN interface options are also accessible.
