Please consult the board-support guide or contact us for specific platform features supported.

Key features include 512 KB L2 cache, integrated security engine, 64-bit DDR1/2 scaling to 667 MHz data rate, dual 32-bit PCI or 64-bit PCI-X, 4-bit serial RapidIO fabric technology and 4-bit PCI Express (or single 8-bit PCI Express 1.0a), local bus I/O interfaces, and four GigE interfaces. The combination of these features makes this device an optimal communications processing solution for Ethernet-only or RapidIO interworking applications, such as enterprise networking, telecom transmission and switching and 3G wireless basestations.

The security engine includes Kasumi algorithm acceleration, making the MPC8548E an ideal choice for enhancing security protocol processing in 2.5G and 3G wireless network infrastructure. This device's integrated security also includes XOR acceleration, which enhances system performance by offloading the compute-intensive parity check in small-medium business enterprise (SME) and redundant array of inexpensive disks (RAID) storage applications.

Freescale designed the MPC8548/E processor to offer a wide range of high-speed connectivity options, including GigE, serial RapidIO technology and PCI Express. Support for these high-speed interfaces enables scalable connectivity to network processors and/or ASICs in the data plane while the MPC8548/E handles complex, computationally demanding control plane processing tasks. The MPC8548/E also features a next-generation double data rate (DDR2) memory controller and 3G wireless encryption.
