Comparison Between C-LANCE (Am79C90)
and LANCE (Am7990) Devices
OVERVIEW
The Am79C90 C-LANCE device is a pin-for-pin equiv-
alent for the Am7990 LANCE device. Using an ad-
vanced 0.8-micron CMOS process, the C-LANCE
device consumes less power than the LANCE device,
which is implemented in an outdated NMOS process.
In addition to the inherent advantages provided by the
advanced CMOS process, the C-LANCE device in-
cludes several functional enhancements over the
LANCE device.
APPENDIX B
Am79C90
The C-LANCE device is available in both 48-pin plastic
DIP and 68-pin PLCC packages. These packages are
socket-compatible with the LANCE packages.
This document provides a comparison of the C-LANCE
and LANCE devices. Table B-1 provides a summary of
the comparison between the two devices. The remain-
der of the document gives details on each item listed in
Table B-1.
