Company Overview
A5The A5 refers to a system-on-a-chip (SoC) designed by Apple Inc. and introduced in 2011, notably powering the iPad 2 and iPhone 4S. It marked a significant advancement in Apple's custom silicon capabilities. While A5 is an Apple product line, its technological lineage and the team's expertise were heavily influenced by Apple's 2008 acquisition of PA Semi, a company founded in 2003 that specialized in designing low-power, high-performance Power Architecture processors. Post-acquisition, the PA Semi team became integral to Apple's in-house chip design efforts, leading to the A-series processors. Therefore, current company data reflects Apple Inc., while historical funding and investor data pertains to PA Semi.
