Bluray Drive Revisions

This table shows all parts mounted from factory on the different PS3 models, and also the compatible replacement parts that was not mounted from factory because was released later but works. When several replacement parts are compatible you should try to aim for the newest one because it superceedes the others (probably at the time the new part started being produced the production of the older part was stopped)

• Notes
  • In lasers models with 2 lenses, one is for CD/DVD, another for Blu-ray
  • Need proper sources, drive info and which PS3 SKU's are having X drive. Please fill in the needed info if possible.
  • The BD controllers starting with CXD are manufactured by sony and the others with R are manufactured by renesas. Starting from CECHKxx every motherboard has 2 revisions of the BD drive, the first uses a sony BD controller and the second a renesas BD controller. This means for some reason (like reducing costs?) sony passes the BD controller production to renesas when they are happy with the new BD controllers

Table explained in short

CECHA, CECHB, CECHC, (some CECHE, CECHG)

Initial FAT models: With BD-400 drive, BMD-001 daughterboard capable for driving KEM-400AAA slide and KES-400A laser.

CECHE

Some have a KES-410ACA dual lens laser with BMD-003 daughterboard.

CECHG

First seen on CECHGxx: Still BD-400 drive, but now with BMD-002 or BMD-003 daughterboard

CECHH, CECHI, CECHJ, CECHK, CECHL, CECHM, CECHN, CECHO, CECHP, CECHQ

Since CECHHxx and later: Changed to BD-410 drive, with BMD-003/BMD-006/BMD-011/BMD-021/BMD-031 daughterboard and KES-410A dual lens laser

CECH2000

CECH-20xx slims introduced BD-450 with BMD-051 daughterboard, capable of driving KES-450A laser and KEM-450AAA slide

CECH2100

CECH-21xx slims also uses BD-450 with BMD-051 daughterboard, capable of driving KES-450A laser and KEM-450AAA slide (but sometimes seen with KES-460A laser)

CECH2500, CECH3000 without daughterboard

CECH-25xx (and later CECH-30xx) series moved the components from the daughterboard to the main PS3 motherboard. Thus there are more/different flatcables used to connect the drive. They are electrical inter-changable (2500<>3000), but mounting differs slightly. It can be modified to fit by cutting some plastic pins on the bottom front of the drive (to make it fit properly with the start/eject board).

KES-460A Laser will work with all slims before the CECH-30xx series.

KES-470A Laser is not backwards compatible and only with CECH-30xx series

CECH4000 toploader

CECH-40xx introduced the toploader (like ps2 slim and old ps1 had) with KEM-850 PHA 0672 assembly.

• KES-450E
• KEM-480AAA unknown PS3 model
• KEM-495AAA CECH-4301C

Remarry BluRay drive

BluRay drive daughterboard is paired with PS3 motherboard, so exchanging a BluRay drive requires remarriage of the BluRay daughterboard. See: Remarry Bluray Drive

BluRay region switcher

This makes changing the BluRay region switching possible. The method described below is using 3 region specific bytes (0x84, 0x85, 0x8C) to change the modelinfo.

Other modelinfo byte values: 0x81 Reference Tool, 0x82 Debug, 0x83 Japan (00), 0x84 North America (01), 0x85 Europe, Middle East, Africa (04), 0x86 South Korea (05), 0x87 United Kingom, Ireland (03), 0x88 Mexico (11), 0x89 Australia, New Zealand (02), 0x8A Singapore, Malaysia (06), 0x8B Taiwan (07), 0x8C Russia, India (08), 0x8D China (09), 0x8E Hong Kong (12)

Payloader method prerequisites:

• LV2 Patcher v9
• patchfiles (see below)

BD Drive IC Components

The drive controller contains a BGA-sized 2MB NOR flash memory chip for Blu-ray drive firmware code, with the contents encrypted. In addition to this, there is a 8MB SDRAM working memory chip. Each drive contains a unique identification number, possibly stored in the SPI Serial Interface Macronix EEPROM. This chip or the NOR flash chip probably stores the device key (and associated sequence keys), and the host private key. The Blu-ray drive is controlled by a Sony Digital Signal Processor chip (CXD6350GG-1, CXD5063AGG-1, CXD5065GB-1, CXD5065-1 depending the SKU) and a Sony CXA2720R Front End Processor chip. Motors/coils are driven by Rohm BA5888FP (Laser Driver - Tracking/Focus Coils driver) and Rohm BD7956FS (Motor Driver - EXP-Motor coils/sled/slot motor driver), of which the Laser Driver uses an OPAMP NJM13403V for Tracking/Focus CTRL.
