Realtek RTL8100B Ethernet Controller
The Realtek RTL8100B is one of the Realtek RTL8139A/B/C/8130 family, the highly
integrated and cost-effective single-chip Fast Ethernet controller that provides 32-bit
performance, PCI bus master capability, and full compliance with IEEE 802.3u 100Base-T
specifications and IEEE 802.3x Full Duplex Flow Control. It also supports Advanced
Configuration Power management Interface (ACPI), PCI power management for modern
operating systems that is capable of Operating System Directed Power Management
(OSPM) to achieve the most efficient power management.
2.3.8.2
Intel 82559ER Ethernet Controller (Optional)
The 82559ER is part of Intel's second generation family of fully integrated 10BASE-
T/100BASE-TX LAN solutions. The 82559ER consists of both the Media Access Controller
(MAC) and the physical layer (PHY) combined into a single component solution. 82559
family members build on the basic functionality of the 82558 and contain power
management enhancements.
The 82559ER is a 32-bit PCI controller that features enhanced scatter-gather bus
mastering capabilities which enables the 82559ER to perform high-speed data transfers
over the PCI bus. The 82559ER bus master capabilities enable the component to process
high-level commands and perform multiple operations, thereby off-loading communication
tasks from the system CPU. Two large transmit and receive FIFOs of 3 Kbytes each help
prevent data underruns and overruns, allowing the 82559ER to transmit data with
minimum interframe spacing (IFS).
The 82559ER can operate in either full duplex or half duplex mode. In full duplex mode the
82559ER adheres to the IEEE 802.3x Flow Control specification. Half duplex performance
is enhanced by a proprietary collision reduction mechanism.
The 82559ER includes a simple PHY interface to the wire transformer at rates of 10BASE-
T and 100BASE-TX, and Auto-Negotiation capability for speed, duplex, and flow control.
These features and others reduce cost, real estate, and design complexity.
The 82559ER also includes an interface to a serial (4-pin) EEPROM and a parallel
interface to a 128 Kbyte Flash memory. The EEPROM provides power-on initialization for
hardware and software configuration parameters.
2.3.9
M-Systems DiskOnChip
M-Systems' DiskOnChip 2000 is a high performance single-chip flash disk in a standard
32-pin DIP package. This unique data storage solution offers cost effective data storage
beyond that of traditional hard disks. Perfect for applications with limited space and varying
capacity requirements. The DiskOnChip 2000 is simply inserted into a 32-pin DIP socket
on your platform board and you have a bootable flash disk.
