DLP2021-Q1: Flash size for DLP2021

Part Number: DLP2021-Q1
Other Parts Discussed in Thread: DLP2010

Hi team,

I don't find any information on our datasheet that clarify the size of the flash for DLP2010 DGP system, but our EVM has a 2Gb one. We can only support the 2Gb size flash? My customer hope it could be extended to 4Gb. Is it possible?

  • Hello Sophie,

    I talked with our systems engineer and he mentioned the following:

    SPI nor flash is only manufactured up to 2Gb. If the customer wants to use 4Gb, they will need to multiplex between two 2Gb flash. 

    Because the bit-planes are decompressed and streamed directly from SPI flash to the DMD, the speed of the SPI flash affects the load time of the DMD. To meet the minimum load time requirement, the high speed octal SPI NOR flash is required to sustain the transfer rate of greater than 300MB/s.

    Here is a proposed design:
