Overview
SPEED provides various interfaces to the PS2, including Ethernet (using an external Ethernet transceiver), IDE/ATA and an UART (to which the modem connects in case of the US-only SCPH-10281 Network Adaptor). It's connected to the PS2-side via SSBUS. 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). It is also used in all PSX models. 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.
Additionaly, it is connected to an external 1k Bit / 128 Bytes EEPROM in both, the Network Adaptor and in SCPH-700XX consoles (what about the PSX?).
Revisions
- 1.1: CXD9624GG (used in some earlier Network Adaptor revisions, including the SCPH-10190 PCMCIA Network Adaptor)
- 1.2: CXD9624AGG (used in some earlier Network Adaptor revisions, including the SCPH-10190 PCMCIA Network Adaptor)
- Adds UART interface for modem (also available in all later revisions)
- 1.3: CXD9731GP (used in later Network Adaptor revisions)
- 1.3: CXD9731AGP (same version reported as the non-PSX CXD9731GP, used in all K-chassis/SCPH-700XX slim consoles)
- 1.4: CXD9731GP (same chip identifier as 1.3, used in all PSX revisions, provides additional PSX-specific interfaces: DVR and Flash)
- Additionaly has interfaces to on-board flash memory and the DVR-portion of the console enabled
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.
