AMD’s AM79C940B series MACE chip re-introduced by Rochester
The Media Access Controller for Ethernet (MACE) chip is a CMOS VLSI device designed to provide flexibility in customised LAN design. The MACE device addresses applications where multiple I/O peripherals are present, and a centralised or system specific DMA is required. The high speed, 16-bit synchronous system interface is optimised for an external DMA or I/O processor system.
