How big is the flash in the rp2040 keyboard controller

How big is the flash in the rp2040 keyboard controller on the FW16? Thanks.

Anwer: 0 bytes. Well, there seems to be a boot rom, but the chip itself comes with 264k of builtin RAM, which can be used for programs and data. Additionally, it can run out of an external flash device which would have up to 8 MByte.
