There are (at least) 3 variants of this chip (note the suffixes "GB" (seems to be related with the hardware packaging) and "101" (seems to be the syscon ROM BOOTLOADER & I/O ports config revision ?) was used later in retail syscon models but in different order. See Syscon_Hardware#Non_retail

• CXR713F120A GB-000 (unknown SoftID) reported for CEB-2040/MPU-501 ...literally as "CXR713F120GB-000" but i guess that was a typo (it was missing the "A" and a space)
• CXR713F120A GB-004 (unknown SoftID) reported above
• CXR713F120A GB-101 (for SoftID 0F3B) used in DECR1000(A/J)

It's very tricky to assign a soft id to the flash syscons, since you can just change the firmware but the label won't change (and Sony reuses these chips).

• CEB-203x GB-000 (000 or 001 is just a placeholder, sometimes these chips ship with a very late firmwares)
• DECR-1000 GB-101 0F3B (also 06DA, 073E, 07FF, 086C, 08F1, 0955, 0AF4, 0B48, 0B74, 0B9D, 0C23, 0D79, 0E4E)
• DEH-H1000A(S)-E GB-201 0B67 (was flashed to 0B8E on some later revisions, no matching label - DEH-H1001-D also reports 0B67)
• CBEH-1004-G GB-004 0B8E (was reused from a CEB prototype console, no matching label)
• unknown GB-202 0C16 (for COK-002 based prototypes)

I think the GB-000 indicates that the flash area is empty, in other words, the syscon manufacturer shipped the chips to sony with the flash area filled either with 0's or 1's and it was sony who wrote the flash (so i agree is a placeholder, but also seems to indicate that it was "empty" when it was sent to sony). In GB-004 the syscon manufacturer wrote something in the flash area and sent the syscons "programmed" to sony (and sony was free to overwrite the flash). And the others starting with GB-10x, GB-20x, GB-30x follows the same name conventions used later in retails, you know... 101, 102, 103 ---> 201, 202, 203 ---> 301, 302, 303 etc...--Sandungas (talk) 22:33, 13 April 2021 (UTC)

The CXR flash chips are never completly empty since you can't overwrite the bootloader/backup bank (seems to be always v0.4.5_b4, no "SoftID"). Also they're made by Sony. If the chip is meant for development they'll put XXX instad of the 000 or 301 but we've never seen one because there needs to be a firmware on the syscon to test the PS3 at the factory, so these are only for internal use. My point is just that you can't use the GB-... label to deduce the version of the firmware which is stored on the chip. M4j0r (talk) 10:31, 14 April 2021 (UTC)

Ok, i thought all the syscons was made by NEC/renesas but after reviewing the info in wiki i reminded are only the sherwood ones, and this talk started talking only about the mullion ones with a Sony SR11/ARM7TDMI CPU, but to be honest even with the mullions sony could have ownership of the patent of the circuitry but ask other manufacturer to build them... and that manufacturer is who "prints" the GB-xxx (with values smaller than 101) based on whatever version they programmed in the EEPROM. With values equal or bigger than 101 this rule doesnt seems to apply though, anyway this talk has been interesting, it was worthy to be mentioned incase someone wonders about that numbers in the old syscons, the reason why i started writing here was mostly because i was wondering about the groups at top of the Template:Motherboard_Components related with syscon, the splitting "by series" is something made lot of time ago that was working fine, the other day i splitted it again "by codename" and i created a new group for the CXR713F120A just as a suggestion for a posible expansion of that pages for the "F" models (incase someone decides to create more pages under that group, im not going to do it), btw, do you know if exists a CXR714F120A ? --Sandungas (talk) 05:59, 16 April 2021 (UTC)

Sony never developed or produced a CXR714F120(A) since the CXR714 is just a downgraded CXR713. The only difference is that the CXR713 has an 32KB data eeprom and the CXR714 only has 20KB. All retail chips do have 384KB of ROM, the flash version does have an 128KB ROM for the bootloader/backup bank and 384KB of flash for the main firmware. So:

• CXR713F120A: 128KB ROM + 384KB Flash + 32KB EEPROM
• CXR713120: 384KB ROM + 32KB EEPROM
• CXR714120: 384KB ROM + 20KB EEPROM

(all of them have 64KB of RAM)
