General Description
The USB to MAC Ethernet Controller is a unique
solution to interface 10/100 Base-T Ethernet devices
to the Universal Serial Bus (USB-2.0).
This device has been specifically designed to
provide a simple solution to communicate with
Ethernet applications. This is accomplished by its
highly integrated functionality.
Ordering Information
Commercial Grade (0 °C to +70 °C)
MCS7830CQ-DA 128-LQFP RoHS
MCS7830CV-DA
80-TQFP RoHS
It is ideal for LAN (Local Area Network) applications.
It provides internal buffering to enable parallel
operations from USB ports on the host side, and
MAC ports on the Ethernet side.
It also provides a serial interface for an EEPROM
for storing the MAC-ID, VID, PID, and other
configurable settings.
