The MatchPort b/g Pro embedded device server is a complete network-enabling solution
on a 1.75"x1.75" PCB. This miniature device server empowers original equipment
manufacturers (OEMs) to go to market quickly and easily with networking and web page
serving capabilities built into their products.
The MatchPort b/g Pro has the following features:
u Power Supply: Regulated 3.3V input required. There are step-down converters
to 1.8V and 1.5V for ICs on board. All voltages have LC filtering to minimize
noises and emissions.
u Controller: A Lantronix DSTni-FX 32-bit microprocessor, running at 166 MHz
internal bus and 83 MHz external bus.
u Memory: 64 Mbits Flash and 64 Mbits SDRAM.
u Ethernet: 10/100 Base TX with auto-negotiation and HP auto-MDIX. On- board
100-ohm terminations included. Users just need an RJ45 jack and 1:1 Ethernet
magnetics with a minimal numbers of discrete components.
u Integrated Ethernet LED Drivers: For connections to Ethernet Link and
Activities LEDs.
u Serial Ports: Two full RS232 serial ports with all hardware handshaking signals.
Baud rates can be standard or customized up to 230 Kbps. RS232/422/RS485
functionalities can also be configured on Serial Port 1.
u Configurable IO Pins (CPs): Up to 7 pins are configurable as general purpose
I/Os if no DTR or DCD is used on serial ports.
u Interface Signals: 3.3V-level interface signals.
u Temperature Range: Operates over an extended temperature range.
