TUSB9261-Q1: Question about capacity of external SFLASH

Part Number: TUSB9261-Q1

A minimum flash size of 512 kbits (64 k x 8) is recommended, but please be aware of any disadvantages in electrical performance when selecting a SFLASH with a larger capacity.

  • Hello,

    So long as the flash satisfies the minimum requirements of 64k x 8, any larger sized flashes should work. The flash burner utility will just leave the addresses above blank. Just do not increase the bit width of the flash, eg a 512kbit flash that is 32k x 16. 

    Best,
