Freescale Semiconductor Inc. is sampling new communications processors based on its 45nm process technology.

The 45nm PowerQUICC, dual-core QorIQ and six-core StarCore DSP announced at the Embedded Systems Conference (ESC) Silicon Valley aim to help OEMs build higher performance 3G and 4G wireless base stations that consume less power, Freescale said.

"OEMs building wireless infrastructure equipment with Freescale's new 45nm parts should reap a significant boost in performance as well as a reduction in both cost and power consumption over previous generation parts," said Linley Gwennap, principal analyst with The Linley Group.

Freescale said it is seeding OEMs with samples of its new 45nm processors, which are currently being designed into a variety of wireless infrastructure equipment. The company expects to begin volume deliveries in the 2H 09.

"We are working very hard to accelerate the delivery schedule for our higher performance 45nm communications processors," said Lisa Su, senior VP and general manager of Freescale's networking and multimedia group. "Even in this economic environment, customers are looking for ways to reduce costs and power consumption in 3G and 4G broadband infrastructure equipment."

Freescale's processors use a 32bit, e500-based PowerPC architecture operating at speeds of up to 1.3GHz, while consuming less than 10W, the company claimed. In Freescale's benchmark tests, power consumption in a typical three-sector, 10MHz LTE base station was reduced by more than 50 percent.

Also at ESC, Mocana Corp. said it will supply security software to OEMs building network equipment using Freescale's PowerQUICC communications processors. Mocana's Device Security Framework leverages integrated encryption and other security acceleration capabilities in the comms processor.

Mocana's API is designed to integrate its software into PowerQUICC-based devices running Linux or other real-time operating systems from Wind River, MontaVista, Green Hills, QNX and ThreadX.
