Description
The MT9080 is a flexible memory module suitable for
use as a basic building block in the construction of
large digital switching matrices. It can be configured
as either a Data Memory or a Connection Memory.
Interface to the device is via 16 bit wide data and
address busses. The MT9080 can operate with
variable clock rates up to 16.7 MHz.
