Overview

This is just a basic comparison of each generation's main components. For a detailed hardware analysis of a generation, click on it's link.

Generation SoC CPU Core RAM NOR/Utility Flash Device Code Name SoC Family Code Name UpdaterFamilyID
iPod nano (1st generation) PP5021C-TDF K4M56163PG (32MiB) SST39WF400A (512KiB) 14/17
iPod nano (2nd generation) S5L8701 ARM940T K4M56163PG (32MiB) SST39WF800A (1MiB) M1 19/29
iPod nano (3rd generation) S5L8702 ARM926 K4X56163PI (32MiB) SST25VF080B (1MiB) N46 M1 26
iPod nano (4th generation) S5L8720 Integrated (32MiB) none N58 M2 31
iPod nano (5th generation) S5L8730 ARM1176 Integrated (64MiB) none N33 M2 34
iPod nano (6th generation) S5L8723 Integrated none N20 36
iPod nano (7th generation) S5L8740 Cortex A5 Integrated (64MiB) none N31 H4 37
iPod classic (6th generation) S5L8702 K4X56163PI (64MiB) SST25VF080B (1MiB) 24
iPod classic (6th generation) S5L8702 K4X56163PI (64MiB) SST25VF080B (1MiB) 33
iPod classic (6th generation) S5L8702 K4X51163PE (64MiB) SST25VF080B (1MiB) 35/38

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.
