GL852 USB-Hub 64-pin as seen on CECHCxx


USB 2.0[edit]

Depending on the SKU Models the PS3 is equiped with 6x (Tool/DECR), 4 or 2 USB (Universal Serial Bus) 2.0 ports with maximum bandwidth of 480 Mbit/s (~57 MB/s), connected internally to a USB-Hub chip.

Note: On PS3 Slim CECH-20xx/DYN-001 and later, the USB port datalines are directly connected to South Bridge without a USB-Hub chip (port is initialised via DC switch IC connected to South Bridge and TH3301 thermistor protect 5V input).

53 39 B This pin is default put in input mode after power-on reset. Individual/gang mode is strapped during this period. After the strapping period, this pin will be set to output mode, and then output high for normal mode. When GL852 is suspended, this pin will output low. *For detailed explanation, please see Chapter 5

Gang input:1, output: 0@normal, 1@suspend
Individual input:0, output: 1@normal, 0@suspend
