Description
The AT75C140 Smart Internet Appliance Processor (SIAP
鈩?/div>
) is a high-performance
processor specially designed for network-enabling consumer and industrial applica-
tions, such as printers, fax machines, industrial automation, data acquisition
equipment and test equipment.
The AT75C140 is built around an ARM7TDMI microcontroller core running at 40 MHz
with a dual Ethernet 10/100 Mbps MAC interface. The specific architecture of the
AT75C140 delivers unmatched performance for low power consumption.
On top of the AT75C140 hardware platform, Atmel provides a special port of the Linux
kernel as the proposed operating system with device drivers for the peripherals.
