The A4 commercially debuted in 2010, in Apple's iPad tablet, and was later used in the iPhone 4 smartphone, the fourth-generation iPod Touch, and the 2nd-generation Apple TV. It combines an ARM Cortex-A8 CPU – also used in Samsung's S5PC110A01 SoC – and a PowerVR SGX 535 graphics processor (GPU), all built on Samsung's 45-nanometer silicon chip fabrication process. The Apple A4 is a PoP SoC manufactured by Samsung, the first SoC Apple designed in-house. They integrate one or more ARM-based processing cores ( CPU), a graphics processing unit ( GPU), cache memory and other electronics necessary to provide mobile computing functions within a single physical package.
The Apple "A" series is a family of SoCs used in certain models of the iPhone, iPad (latest iPads Pro and Air use the Apple M1 SOC), iPod Touch, the discontinued original HomePod, and the Apple TV digital media player. The APL2298 (also S5L8922) is a 45 nm die shrunk version of the iPhone 3GS SoC and was introduced on September 9, 2009, at the launch of the third-generation iPod Touch.Ī series Evolution of Apple "A" series It was manufactured by Samsung on a 65 nm process. It includes a 600 MHz single-core Cortex-A8 CPU and a PowerVR SGX535 GPU.
The APL0298 (also S5L8920) is a PoP SoC introduced on June 8, 2009, at the launch of the iPhone 3GS. It was manufactured by Samsung on a 65 nm process. It includes a 533 MHz single-core ARM11 CPU and a PowerVR MBX Lite GPU. The APL0278 (also S5L8720) is a PoP SoC introduced on September 9, 2008, at the launch of the second-generation iPod Touch. The iPhone 3G and the first-generation iPod Touch also use it. It was manufactured by Samsung on a 90 nm process. It includes a 412 MHz single-core ARM11 CPU and a PowerVR MBX Lite GPU. The APL0098 (also 8900B or S5L8900) is a package on package (PoP) system on a chip (SoC) that was introduced on June 29, 2007, at the launch of the original iPhone.
They combine in one package a single ARM-based processing core ( CPU), a graphics processing unit ( GPU), and other electronics necessary for mobile computing. Apple first used SoCs in early versions of the iPhone and iPod Touch.
