The PS4 contains at least one Serial Flash chip, and depending on the motherboard model (for example those that have the Aeolia Southbridge) can also have one flash for a SATA Bridge, one flash for a USB 3.0 Hub, one flash for a Communication Processor in the DevKit case or even more flash chips on prototype motherboards.
Main Serial Flash[edit | edit source]
SATA Bridge Serial Flash[edit | edit source]
A serial flash chip contains the firmware and configuration for the SATA bridge device to which it is connected.
SATA Bridges models on PS4:
- MB86C311B: uses MX25L1006E or 25X10CLYA1 serial flash chips
USB 3.0 Hub Serial Flash[edit | edit source]
A serial flash chip contains the firmware and configuration for the USB 3.0 hub device to which it is connected.
USB 3.0 Hubs models on PS4:
- GL3520: uses MX25L1006E or 25X10CLYA1 serial flash chips
- CYUSB3312-88LTXC: no known serial flash
- CYUSB3314-88LTXC: no known serial flash
Remarks[edit | edit source]
Serial flash chips used in PS4 have several OTP/blocking options according to datasheets, but they seem not used, as seen when handling flash or replacing flash itself.
