Freescale Semiconductor MPC8555E Block Diagram

The MPC8555E PowerQUICC III processor targets wired and wireless communications applications and imaging applications, such as VPN and firewall routers, branch office and enterprise routers, switches, printing and imaging systems, telecommunications systems, wireless infrastructure, integrated access devices, multi-service access platforms and media gateways. The MPC8555E processor is a high-performance integrated communications processor. The MPC8555E, like the MPC8541E, offers a security engine supporting a wide variety of algorithms, public key, and a random number generator, making it suitable for network security applications, such as VPN and firewall routers.

The MPC8555E contains a Communications Processor Module (CPM) that provides up to two 10/100 Ethernet ports, up to two UTOPIA interfaces for OC-3 ATM support, up to 2 TDMs, HDLC, transparent and other legacy protocols. Other key features include the e500 core built on Power Architecture technology running up to 1 GHz, 256-kbytes L2 cache, dual 10/100/1000 Ethernet controllers, a DDR memory controller, a 32/64-bit PCI controller, a 4-channel DMA, a multi-channel interrupt controller and a DUART serial interface. The MPC8555E support CPU speeds from 533 MHz to 1 GHz. Versions with or without the security engine are available. Extended temperature (-40 to 105C) is available at 667 MHz.

Freescale's PowerQUICC III processors are supported by CodeWarrior development tools from Freescale and by an ecosystem of development tools, operating systems, and applications from third-party vendors. The MPC8555CDS development system and CWH-PPC-8555N-VX QUICCstart development system are available for the MPC8555E.
