Freescale’s MPC8640D processor debuts as a lower power, lower cost version of the MPC8641D device


Available in single or dual core versions, the MPC8640D delivers AltiVec processing and high performance for less

AUSTIN, Texas.– Freescale Semiconductor introduces the MPC8640D – a lower cost, lower power version of the MPC8641D dual core processor. The device is available in single and dual core versions and is ideal for networking, telecom, pervasive computing, aerospace and defense applications.

The MPC8640D enables customers to utilize high performance e600 Power Architecture® cores and AltiVec® 128-bit vector processing at lower price points and power requirements. The MPC8640D processor runs at 1.0/1.25 GHz per core while consuming up to 27 percent less power and costing up to 37 percent less than its MPC8641D predecessor.

The MPC8640D processor features software, package and pin-for-pin compatibility with the MPC8641D processor. It is also compatible with Freescale’s forthcoming QorIQ™ devices, and Freescale simplifies development via an available MPC8641D development platform which comes with a Linux® board support package (BSP).

“This device continues Freescale’s track record of delivering high levels of integration and performance while keeping power requirements low,” said Glenn Beck, marketing manager with Freescale’s Networking Systems Division. “We expect the MPC8640D to prove especially attractive to markets where power/performance ratios are critical.”

A highly integrated device, the MPC8640D processor incorporates two e600 cores each with 1 MB of L2 cache. Each core also features the industry benchmark 128-bit AltiVec vector processing engine. The AltiVec engine commonly achieves a 2x to 12x performance increase as demonstrated by EEMBC benchmarks (

High-speed I/O connectivity is delivered via an integrated DDR1/DDR2 memory controller, dual PCI Express® and RapidIO® controllers and quad Ethernet controllers. With dual core performance as well as integrated northbridge and southbridge functionality, this single chip can replace what could take up to four chips using typical solutions. Additionally, all core-to-peripheral connections are internal, so board designers avoid difficulties related to laying out high-speed parallel buses.

A standard temperature range of 0-105 degrees C is now qualified and the extended temperature range of 40-105 degrees C is expected to follow soon.

The MPC8640D processor is supported by extensive enablement solutions from software vendors including Green Hills, MontaVista, QNX and Wind River. Additionally, leading high performance embedded computing solution providers Curtiss-Wright and GE Fanuc both plan to deliver products based on the device during the second half of 2008.

Pricing and availability
The dual core version of the MPC8640D (MC8640DVU1000HC) is available at a suggested retail price of $120 in 10K quantities, and the single core version (MC8640HX1000HC) is available at a suggested retail price of $90 in 10K quantities. The MPC8641D Reference Design Board (MCEVALHPCN-8641D) is available at a suggested retail price of at $3,075. All pricing is in USD.
