Part Number: TUSB9261

Hi I am using TUSB9261 in my design when i checked SPI flash recommendations in the TUSB9261 implementation guide document all the 5 flash options shown in the document are Obsolete. can you recommend me a  flash chip that is can use and program it in the same way as your demo board (in circuit programming: connecting TUSB9261 chip to a PC using usb port and programming flash using TUSB9261 SPI lines).

thank you.
