A4.jpg

A system on a chip ("SoC") developed by Apple's in-house chip design department. Publicly, Apple refers to this chip as the A4. Internally, this processor is also based on the S5L8920X family, which can also be seen through the reuse of several MMIO devices and MMIO device registers (i.e: chipid). This was the last SoC revision on mobile devices manufactured for Apple that has a publicly known exploitable bootrom vulnerability until the title was taken by checkm8.

Specifications

Aside from the iPhone 4's additional RAM and an overall higher clock speed, these are the same specifications as the S5L8920 and S5L8922.
