IA21140AF Preliminary Data Sheet PCI FAST ETHERNET LAN CONTROLLER innovASIC Features • Form, Fit and Function Compatible with the DEC™ 21140AF • Available in 144 Pin PQFP Package • Integrated Ethernet controller with PCI bus interface • Supports 10 Mb/s and 10/100 Mb/s network interface • PCS and scrambler/descrambler circuitry on chip • Supports multiple PCI features: - Unlimited PCI burst - PCI read multiple - PCI write and invalidate - PCI read line - PCI 5.0V and 3.3V environments • Multiple interrupt sources • Contains two independent 3K FIFOs to minimize external memory additions • Provides sleep or snooze low-power modes • Interfaces with MicroWire™ Serial ROM • Provides a JTAG test port with boundary scan function • Complies with IEEE 802.3, ANSI 8802-3, and Ethernet standards The IA21140AF is a "plug-and-play" drop-in replacement for the original IC. innovASIC produces replacement ICs using its MILESTM, or Managed IC Lifetime Extension System, cloning technology. This technology produces replacement ICs far more complex than "emulation" while ensuring they are compatible with the original IC. MILESTM captures the design of a clone so it can be produced even as silicon technology advances. MILESTM also verifies the clone against the original IC so that even the "undocumented features" are duplicated. This data sheet documents all necessary engineering information about the IA21140AF including functional and I/O descriptions, electrical characteristics, and applicable timing.
