Download the AM79C970A datasheet PDF. This datasheet also covers the AM7 variant, as both devices belong to the same pcnet-pci ii single-chip full-duplex ethernet controller for pci local bus product family and are provided as variant models within a single manufacturer datasheet.

General Description

The 32-bit PCnet-PCI II single-chip full-duplex Ethernet controller is a highly integrated Ethernet system solution designed to address high-performance system application requirements.

Key Features

  • Automatic retransmission with no FIFO reload.
  • Automatic receive stripping and transmit padding (individually programmable).
  • Automatic runt frame rejection.
  • Automatic selection of received collision frames Microwire EEPROM interface supports jumperless design and provides through-chip programming Advanced Micro Devices Supports optional Boot PROM for diskless node.
