The Marvell® 88F6281 SoC with SheevaTM embedded CPU technology, is a high-performance integrated controller. It integrates the Marvell Sheeva CPU core which is fully ARMv5TE-compliant with a 256KB L2 Cache. The 88F6281 builds upon Marvell’s innovative Feroceon® family of processors, improves performance, and adds new features to reduce bill of materials (BOM) costs. The 88F6281 is suitable for a wide range of applications such as routers, gateway, media server, storage, set-top-box, networking, point of service and printer products. The 88F6281 offers unparalleled integration that makes system design simple and cost efficient. The SoC integrates: 

  • High-performance single-issue CPU>

  • 1.0 Ghz - 1.2 Ghz operating speed

  • 16KB-Instruction and 16KB-Data 4-way, set-associative L1 cache

  • 256KB unified 4-way, set-associative L2 cache

  • 16-bit DDR2 memory interface (up to 800 MHz data rate)

  • Two Gigabit Ethernet MACs with interface options

  • Precise Timing Protocol and Audio Video Bridging

  • Single PCI-Express port

  • Single USB 2.0 port with integrated PHY

  • Two SATA 2.0 ports with integrated PHYs
