　　The QorIQ P1 platform series, which includes the P1016 and P1025 communications processors, offers extensive integration and extreme power for a wide variety of applications in the networking, telecom, defense and industrial markets. Based on 45 nm technology for low-power implementation, the P1016 and P1025 processors provide single- and dual-core solutions for the 400 MHz to 667 MHz performance range, along with advanced security, QUICC Engine for multiprotocol support and a rich set of interfaces.

　　The QorIQ P1016 and P1025 processors are pin-compatible with the QorIQ P1015, P1024 products, and software compatible with the P1011/P1020 and P2010/P2020 offering a six-chip range of cost-effective solutions. Scaling from a single core at 400 MHz (P1015) to a dual core at 1.2 GHz per core (P2020), the two QorIQ platforms deliver an impressive 4.5x aggregate frequency range.
