A system on a chip ("SoC") developed by Apple's in-house chip design department. It is used in iPad, both models of the iPhone 4 (GSM and CDMA), Apple TV 2G and the iPod touch 4G. 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).

Specifications
- CPU: ARM Cortex-A8
- GPU: PowerVR SGX 535
- A/V Playback: PowerVR VXD
- RAM: 256 MB (Apple TV 2G, iPad, and iPod touch 4G) or 512 MB (iPhone 4)
Aside from the iPhone 4's additional RAM and an overall higher clock speed, these are the same specifications as the S5L8920 and S5L8922.
