|Designed to meet demands for low cost, easy implementation and superior network performance, the ETRAX 100 is Axis' fifth-generation optimized system-on-a-chip solution for putting peripherals on the network. The ETRAX 100 was developed using 0.35µm ASIC technology with the best price/performance ratio available today. It is a member of the ETRAX RISC chip family with more than 1 million units shipped, making it the most widely used network-attached architecture. Applications include networked printers, copiers, multi-function peripherals and network-attached storage.|
RISC CPU Delivers Exceptional Performance with Low Power Consumption
|The innovative 100 MIPS 32-bit RISC design delivers compact code and exceptional price/performance at low power consumption. An 8-kbyte on-chip cache helps to take full advantage of the CPU performance. An optimized C/C++ compiler is available.|
|Network Controller Simplifies Design and Improves Throughput||The on-chip Fast Ethernet controller simplifies the hardware design as most logical and physical connectivity is on one chip. The controller also provides excellent network throughput and supports zero copy network protocol stacks.|
|Feature-rich I/O Makes It Suitable for a Wide Range of Applications||Intelligent DMA-driven ports provide cost-effective connections to devices with SCSI-2, SCSI-3, EIDE/ATA-2, parallel, and serial interfaces. The ETRAX 100 has a DMA data transfer rate of up to 200 Mbytes/second, which supports the most demanding of network applications today and in the future.|
|Memory Bus Interfaces Lower Product Design Costs||The ETRAX 100 has 2 Gigabytes of address space and supports SRAM, DRAM, EPROM, EEPROM, and Flash PROM without external logic, which lowers cost and makes design easy.|
|Network Bootstrap Provides Extra Reliability for Thin Servers||The ETRAX 100 features a patent-pending network bootstrap function which enables ETRAX 100-based products to be booted remotely over the network, even if they have no executable program code in memory.|
Management Tools and Multiple OS Support Complete the Solution
ETRAX is a part of Axis' ThinServer Technology, which consists of protocol stacks, server software, "thin" versions of real-time operating systems and Web-based management tools. Axis' core architecture supports open standards such as SLP, Sun's Jini and the Ericsson-led "Bluetooth" wireless initiative.
|32-BIT RISC CPU||
RISC CPU with 32-bit data and address format. 15 general 32-bit registers. Instruction set optimized for compact code and high speed with 16/32-bit bus width. Peak performance of 100 MIPS.
8 kbyte on-chip direct mapped unified instruction/data cache memory.
|Ethernet Controller||Ethernet controller supporting 100 Mbit and 10 Mbit (compatible with IEEE 802.3 and Fast Ethernet standards). ETRAX 100 interfaces to 100 Mbit/10 Mbit MII and 10 Mbit NS DP8391A Serial Network Interface.|
Ten internal DMA channels provide handling of data within the chip as well as to and from external units. The channels are unidirectional, five in each direction. Two channels for external I/O are provided. Each of those uses two internal channels, one in each direction.
Eight of the DMA channels have a 64 byte FIFO. The two channels used for serial port 1 do not have FIFOs.
The ten DMA channels can be configured for connecting to SCSI, EIDE/ATA-2, parallel ports, serial ports, and memory. These applications are multiplexed on the same pins. Combinations where the applications do not overlap are allowed. There are two additional serial ports that are always available. Channel usage is decided by setting internal registers.
|Initiator (host) mode SCSI controller that supports either two 8-bit wide or one 16-bit wide SCSI interface. Synchronous and asynchronous data transfer are supported. External bus drivers are required. The disk interface can also be configured as an EIDE/ATA-2 port with support for up to 8 disk drives. The SCSI ports and the EIDE/ATA-2 interface are multiplexed on the same pins as the parallel ports and two of the serial ports. Configuration is decided by internal registers.|
|Two Parallel I/O Ports
FastInterface based on 1284.4
The ports can be configured to support various parallel printer protocols, including
|FOUR Serial Ports||
Supports baud rates from 300 up to 1843200 baud and a non-standard baud rate of 6.25 Mbaud. Two of the ports are constantly available and two are multiplexed with other I/O. Baud rate and operating mode can be set independently for each channel. Operating modes:
|Bootstrap Program Download||Support for initial loading to internal cache memory from serial port and network. Code, loaded to cache, can be designed to enable download of program to initially empty Flash PROM or other external memory.|
16-bit/32-bit bus interface supporting SRAM, DRAM, EPROM, parallel EEPROM, and FlashPROM without external logic.
A 25-bit address bus, using bits 1 to 25, gives an address space of 64 MB per memory bank. The bus width and number of waitstates can be configured individually for EPROM, SRAM and DRAM banks. Maximum bus cycle frequency is 50 MHz.
|General Purpose Ports||Two general purpose ports that each contain 8 bits of individually controlled I/O-pins|
|Clock Generator||Internal 100 MHz operating frequency, generated by a PLL from an external 20 MHz clock signal.|
ETRAX 100 provides vectorized interrupt, internal (I/O ports, network interface, DMA, and timer) and external (IRQ and NMI).
C, C++ compiler: Cross compiler running on SUN SPARC platform. (Based on GNU CC from Free Software Foundation.)
Logic Analyzer support: Specially designed logic analyzer from Axis Communications enables tracing of code execution from internal cache.
