DLP9500: Difference EVM of DLP9500 and DLP6500

Part Number: DLP9500

Hi,

I am planning to use DMD as a spacial light modulator and now considering the EVM of DLP6500 and DLP9500. However, I am a bit confused. For DLP LightCrafter 6500, the "Driver" and "Configuration PROM" options are set as "n/a" compared to DLP Discovery 4100 for DLP9500. Is that means that I need to order extra "Driver" and "Configuration PROM" if I want to use DLP LightCrafter 6500?

Thanks.

  • Hello Mingyang,

    First, welcome to the DLP section of the TI-E2E forums.

    The architecture of both the DMD and their controllers is very different for these two platforms.  

    The DLP9500 requires and external driver (the DLPA200) and for the DLP6500 DMDs an equivalent of this driver is inside the DMD package and does not require a separate driver chip.  This is why the for the LightCrafter 6500 EVM (DLPLCR6500EVM) the "Driver" is set as "n/a".

    The DLP9500 is driven by the DLPC410 controller which is simply an Xilinx Virtex-5 LX30 FPGA loaded with our controller configuration which is securely stored in the associated DLPR410 PROM.  The DLPR410 contains the TI IP that configures the Virtex 5 as a DLPC410 controller.  That is why the DLP9500 requires a "Configuration PROM"

    The DLP6500 in the DLPLCR65000EVM is driven by the DLPC900 controller, which is a special TI ASIC.  There is some configuration data stored in the firmware that is provided for this platform, but it is stored in the on board parallel flash memory, and does not require a separate "PROM".  There are several flash memories that can be used and is a choice of the end user when designing their own platform. 

    Therefore when the DLPC900 is used to drive a DLP6500 DMD no "PROM" is required.  However, when designing a DLPC900 / SLP6500 system, an appropriate flash memory will have to be designed into the system.
