Designed to meet demands for low cost, easy implementation and superior network performance, the ETRAX FS is Axis' seventh-generation optimized system-on-a-chip solution for putting peripherals directly on the network.

The ETRAX FS includes, within a single system-on-chip device, a 200 MIPS 32-bit RISC processor plus dual on-chip 10/100 megabit Ethernet controllers, a wide range of device interfaces including multiple high speed serial ports and an integrated USB 1.1 PHY. The device comes in a 256-pin PBGA package and uses 465 mW power (typical). The ETRAX FS was developed using 0.13 m ASIC technology, giving it one of the best price/performance ratios available today.

The ETRAX FS runs the standard Linux 2.6 kernel and Axis provides a tested distribution with associated software components, all available in the SDK on the Axis developer website.

High Performance, Low Power Consumption
With its improved instruction set, ETRAX FS has 2.7-3 times more CPU performance and 8 times more internal bandwidth than its predecessor ETRAX 100LX. The CRIS CPU core (CRIS v32) now has a 5 stage pipeline, separate instruction and data caches (16 kbyte each) with 256-bit wide data buses.
For extra demanding applications or drivers, ETRAX FS also has an on-chip RAM of 128 kbytes, 256 bit wide, with 20 ns cycle time. Several power-save modes are also available.
Designed for Networking
Dual 10/100 Mbit/s full duplex Ethernet controllers make the ETRAX FS ideal for networking high performance devices.
Crypto Accelerator
Hardware accelerated wire-speed cryptography allows efficient implementation of cryptography protocols and applications. Supported crypto algorithms are AES, DES, 3DES. Supported hashing algorithms are SHA-1 and MD-5. Throughput 200 - 3000 Mbit/s depending on selected operations.
Built in Memory Controllers for Low Product Cost
The ETRAX FS has 4 GB of address space. It supports SDRAM, SRAM, EPROM, EEPROM, and NOR/NAND Flash PROM without external logic for fewer components and lower cost.
I/O Protocol Processor for Flexible Device Attachment
A patented micro-code programmable I/O protocol processor adds great flexibility to the product as it can be used to connect many types of devices to the system. Examples of protocols that can run in the I/O Processor are parallel and serial ports, PC-Card, CardBus, PCI, USB FS/HS host, USB FS device, SCSI and ATA. The I/O Processor has real-time performance and consists of three 200 MHz 32-bit processors with local memory and hardware accelerators.
Runs the Real Linux - Rapid Development
Thanks to the included MMU, ETRAX FS can run the real Linux 2.6 kernel. All the familiar Linux tools greatly reduces the up-front investment and learning time for developers. Free powerful debugging features available include:
  • Strace is used on an application to trace which system calls it makes and which signals it receives from the kernel. It is a standard system tool, available on Linux host systems.
  • GDB, both user mode and kernel mode
  • Stub-less debug via JTAG TAP (requires a Xilinx Parallel Cable IV)
  • Watchdog timer for self-diagnostics and increased reliability
