SPEED provides various interfaces to the PS2, including Ethernet, where it functions as a MAC (using an external Ethernet transceiver/PHY), IDE/ATA and an UART (to which the modem connects in case of the north-american-only SCPH-10281 [[Network Adaptor]] and some north-american SCPH-700XX PS2 slim variants).

It's connected to the PS2-side via [[SSBUS_controller|SSBUS]] (PCMCIA in SCPH-1X000 consoles). For fat models, it comes inside the network adaptor. For slim models, it comes on the motherboard for SCPH-700XX consoles, with the IDE pins still exposed on the PCB, making it possible to connect a hard drive (which is, however, not practical in most cases, as it requires a lot of wires and soldering). Starting with SCPH-750XX consoles, SPEED was not used anymore, as its functions of an network controller were integrated into the newly developed PPC405-based [[IOP/Deckard]], with the IDE interface being removed entirely. | ||

Later slim consoles don't have a dedicated SPEED chip anymore, as the functionality has been integrated into [[IOP]]. These consoles report SPEED version 1.3. | Later slim consoles don't have a dedicated SPEED chip anymore, as the functionality has been integrated into [[IOP]].
