Please provide the following information for each chip: | Please provide the following information for each chip: | ||
- | * Required: markings on the chip | ||
- | * Do not just send me the chip code name and expect me to know which one it corresponds to | ||
- | * Ex: specify " | ||
- | * Optional: alternate names | ||
- | * Ex: SWIM, Pentium 1 etc | ||
- | * These are helpful to add to wiki pages | ||
- | * Required: what you want | ||
- | * Full images of every layer so you can digitize it? | ||
- | * Do you need the whole die or just a part of it? | ||
- | * Top metal image for aesthetic purposes? | ||
- | * Are you hoping for high resolution that can see every wire or just an overview shot? | ||
- | * ROM dump? | ||
- | * Suggested method? | ||
- | * Image mask ROM only? | ||
- | * Erase fuses / laser magic? | ||
- | * Optional: datasheet is a plus, especially if I need to do something invasive | ||
- | * If applicable: any previous knowledge of things people tried that didn't work | ||
- | * Required: replaceability/ | ||
- | * Sometimes I can do something more aggressive (faster, sometimes much faster) that might have higher chance of damage | ||
- | * If they are readily available you should send me several just in case | ||
- | * Especially if you want me to do invasive analysis (ex: delayer) | ||
- | * TODO: come up with a scale, but here are some rough figures | ||
- | * Very common: < $5 or can easily get for free | ||
- | * Ex: XC2C32A | ||
- | * Common: can get more if you shell out mild cash | ||
- | * Ex: playstation 1 CPU | ||
- | * Rare: You can probably get more but it might take a while or cost >$100 | ||
- | * Ex: playstation 4 CPU | ||
- | * Very rare: $1000 or un-replaceable | ||
- | * Ex: CSG 4510 R3 (the C65 CPU) | ||

I do lots of chips for others, but I give priority to people that are able to provide funds. This section is written with open source projects as the main audience, but note I also offer services through my embedded security consulting service. |

+ | In terms of consumables, | ||
+ | |||
+ | Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). Similar issues with staining and lapping. | ||

+ | I prefer to focus on chips that I can (eventually) release on siliconpr0n.org, | ||

+ | In general I want to focus on R&D / labwork and not hand digitization. | ||
+ | |||
+ | Most of this is targeted towards small chips up to the mid 90' | ||
+ | |||
+ | Other: most of the work is in decapping, not actual imaging. If you happen to already have a bare, clean die and would be satisfied with a quick / lower quality scan, feel free to send me a few dies. This also can work out well since most of the NRE cost is in the microscope, not the decapping supplies. | ||
