2.3.7.2Intel 82559
The Ethernet interface is based on an Intel 82559 Ethernet controller that supports both 10BASE-T and 100BASE-TX. The 82559 consists of both the Media Access Controller (MAC) and the physical layer (PHY) interface combined into a single component solution.
The 32-bit PCI controller provides enhanced scatter-gather bus mastering capabilities and enables the 82559 to perform high speed data transfers over the PCI bus. Its bus master capabilities enable the component to process high level commands and perform multiple operations, which lowers CPU utilization by off-loading communication tasks from the CPU. Two large transmit and receive FIFOs of 3 Kbyte each help prevent data under runs and overruns while waiting for bus accesses. This enables the 82559 to transmit data with minimum interframe spacing (IFS).
2.3.8ITE IT8712F-A
The Winbond W83977TF-AW Super I/O chip provides most input / output interfaces of the system as the following:
COM 1/2. RS-232/RS-422/RS-485 driver are used whereby RS-232, RS-422 and RS- 485 are provided. Mode can be selected by setting hardware jumper. Drivers use charge pumps whereby only +5V is required
LPT. Support for SPP, EPP and ECP modes
Floppy interface
Keyboard interface
PS/2 Mouse interface
IrDA interface for infrared communication. This interface shares the controller of COM2
Provision of buffered ISA databus for BIOS (denoted XDBus)
NVRam with battery backup for BIOS configuration and real time clock
2.3.9M-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.
