- Snippet from Wikipedia: Apple A4
The Apple A4 is a 32-bit package on package (PoP) system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series, and manufactured by Samsung. It was the first SoC Apple designed in-house. The first product to feature the A4 was the first-generation iPad, followed by the iPhone 4, fourth-generation iPod Touch, and second-generation Apple TV.
The last operating system update Apple provided for a mobile device containing an A4 (iPhone 4) was iOS 7.1.2, which was released on June 30, 2014 as it was discontinued with the release of iOS 8 in September 2014.
The iPad (1st generation) was discontinued earlier than the iPhone 4 with the release of iOS 5.1.1 on May 7, 2012 because it only had 256 MB of RAM compared to 512 MB on the iPhone, and the fact that applications would crash more frequently with the graphics using a large portion of the RAM.
The last operating system update Apple provided for an Apple TV containing an A4 (second-generation Apple TV) was Apple TV Software 6.2.1, which was released on September 17, 2014.
