AMD Lance Am7990 IEEE 802.3[1] Ethernet media access controller (MAC) controller were introduced in 1985.[2] Its architecture is the basis for AMD's PCnet Family of highly integrated single-chip Ethernet controllers. The one exception is the Am79C940 MAC.
The Am7990 chip was fabricated in NMOS technology and has no integrated Manchester encoder/decoder (ENDEC) nor does it have an integrated 10BASE-T transceiver.
