Syscon Hardware

Syscon 1st Generation (BGA Packaging)

Syscon is the main power controller chip. It is responsible for powering up the various power systems and for configuring and initialising the CELL, RSX and southbridge. It communicates with these devices via seperate SPI busses. There is external access by JTAG (Which appears to have been disabled after factory programming) and Serial.

Generation 1: CXR713120-201GB

Syscon 1st Generation (BGA Packaging)

Early PS3 : up to including CECHK/DIA-002

Packaging

The first generation of the chip comes in a 200 pin BGA package as per below:

Generation 2: SW-301 / 2-2: SW2-301

Newer generation Syscons are first to be seen on PS3 FAT CECHL/VER-001 board up to CECHQ/VER-001, later replaced by an updated version (with the same pinout) on the PS3 slim CECH-20..A/DYN-001 and later.
