Although iPods have many other components, here we are only listing the components that might be relavent to cracking firmware encryption. If you have any suggestions for any other components to add, just post on the talk page or IRC. Links to datasheets are important if they can be found. For a visual hardware reference, visit the [[Hardware annotation]] page.

| Samsung S5L8701 System On Chip (SoC), includes ARM940T central processor, advanced DSP, 50kB boot ROM, 256kB SRAM, external RAM, flash and LCD controllers, USB(1.1-host; 2.0-function) and some other parts. Package: [http://www.samsung.com/global/business/semiconductor/support/PackageInformation/downloads/SystemLSI/FBGA/232_FBGA_1010_12_05.pdf 232-pin FBGA 10x10mm] or 224/226-pin 9x9mm. Similar chips: [http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=212&partnum=SA58700 SA58700X07].  Some documentation available for the S5L series can be found [[S5L8700 datasheet|here]]. The processor itself is Apple-branded and marked 337S3291 8701.

* '''SoC Family Code Name''': device family code name, seems to follow large generational changes in SoC. Mostly seen around hardware (init) code, eg. flash interface, diags, etc.

Explanations

  • Device Code Name: product code name, from early prototype phases to production run device. Most commonly used internal reference.
  • SoC Family Code Name: device family code name, seems to follow large generational changes in SoC. Mostly seen around hardware (init) code, eg. flash interface, diags, etc.
