DP83932C-20/25/33 MHz SONIC^TM

Systems-Oriented Network Interface Controller

General Description

The SONIC (Systems-Oriented Network Interface Control-

ler) is a second-generation Ethernet Controller designed to

meet the demands of today’s high-speed 32- and 16-bit sys-

tems. Its system interface operates with a high speed DMA

that typically consumes less than 3% of the bus bandwidth

(25 MHz bus clock). Selectable bus modes provide both big

and little endian byte ordering and a clean interface to stan-

dard microprocessors. The linked-list buffer management

system of SONIC offers maximum flexibility in a variety of

environments from PC-oriented adapters to high-speed

motherboard designs. Furthermore, the SONIC integrates a

fully-compatible IEEE 802.3 Encoder/Decoder (ENDEC) al-

lowing for a simple 2-chip solution for Ethernet when the

SONIC is paired with the DP8392 Coaxial Transceiver Inter-

face or a 10BASE-T transceiver.

management uses two areas in memory: one for indicating

status and control information and the other for fetching

packet data. The system can create a transmit queue allow-

ing multiple packets to be transmitted from a single transmit

command. The packet data can reside on any arbitrary byte

boundary and can exist in several non-contiguous locations.

Features

32-bit non-multiplexed address and data bus

High-speed, interruptible DMA

Linked-list buffer management maximizes flexibility

Two independent 32-byte transmit and receive FIFOs

Bus compatibility for all standard microprocessors

Supports big and little endian formats

Integrated IEEE 802.3 ENDEC

For increased performance, the SONIC implements

Complete address filtering for up to 16 physical and/or

multicast addresses

unique buffer management scheme to efficiently process,

receive and transmit packets in system memory. No inter-

mediate packet copy is necessary. The receive buffer man-

agement uses three areas in memory for (1) allocating addi-

tional resources, (2) indicating status information, and (3)

buffering packet data. During reception, the SONIC stores

packets in the buffer area, then indicates receive status and

control information in the descriptor area. The system allo-

cates more memory resources to the SONIC by adding de-

scriptors to the memory resource area. The transmit buffer

Full-duplex loopback diagnostics

Fabricated in low-power CMOS

132 PQFP package
