TK71-1221: Marvell Kirkwood 1.2GHz ARM5 512/128MB QSeven Computer on Module

 TK71

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

• Network security engine with various encryption algorithm support

• Audio and MPEG Transport Stream Interface

• Two TDM Channels, SDIO, NAND flash, SPI, TWSI, and Two UART interfaces

   

The innovative, on-chip crossbar architecture with any-to-any connectivity enables concurrent transactions among multiple units that results in high system throughput allowing system designers to create high-performance scalable systems. Tightly integrated CPU and memory controller significantly improves application performance.
