Wireless Networking
The PS3 contains two wireless technologies, Wi-Fi 802.11b/g and Bluetooth 2.0. It is not possible for both to be used at the same time, so the PS3 alternates between Wi-Fi and Bluetooth communication at a very fast frequency using time division multiplexing. Both wireless capabilities are powered by the Marvell 88W8580 chip. In models CECHL and later, this wireless module became part of the motherboard, and is no longer on a separate daughterboard.
Hardware
Marvell 88W8580 WLAN chip
The Wi-Fi module uses two internal antennas and allows the PS3 to communicate with access points and Wi-Fi devices like the Sony PSP. The Wi-Fi module contains a 16MB ISSI SDRAM memory chip, and a 64KB SPI Serial Interface NOR Macronix flash chip.
| Type | Size | Speed | Voltage | Packaging | Manufacturer | Serialnumber | Description |
|---|---|---|---|---|---|---|---|
| NOR Flash | 64KB | 85MHz | 3V | 8-pin | Macronix | MX25L512MC-12G | PS3 Wi-Fi firmware chip |
| SDRAM | 16MB | 166MHz, 6ns | 3.3V | 90-ball | ISSI | IS42S32400B-6BL | PS3 Wi-Fi working memory chip |
| RAM | 16MB | Nanya | NT5SV8M16FS-6K | PS3 Wi-Fi working memory chip (CECHJ and later models) |
Software
eCos is used to provide the Playstation's Wi-Fi support. eCos is an open source real-time operating system (RTOS). It is licensed under a modified version of GPL that allows the use of non GPL licensed code to be linked with eCos.
