HANDLING PRECAUTIONS

STATIC ELECTRICITY

The CMOS integrated circuits on the 4I60 can be damaged by exposure to electrostatic
disch arges. The fol l owing precautions sh ould be taken when h andl in g the 4I60 to prevent possib le
damage.

A. Leave the 4I60 in its antis tatic bag until needed.

B. Al l work should be perf ormed at an antistatic workstation.

C. Ground equi pment in to which 4I60 w ill be i nstal led.

D. Ground handl ing personnel with conductiv e bracelet through 1 megohm resistor to ground.

E. Avoi d wearing syntheti c fabri cs, particul arly Nyl on.

INTRODUCTION

GENERAL

The 4I60 is a high performance PCI 100BaseT Ethernet card in a PC/104-PLUS form factor.
PC/104-PLUS is a new embedded system card format that adds a st ackable PCI connector to t he
PC/104 standard.

The 4I60 is a bus ma steri n g PCI Ethernet card using the Di gital Sem iconductor 21143 Ethernet
chi p. The bus masteri ng architecture of the 21143 m ini mi zes CPU inv olvement i n packet transmiss ion

and reception. The large receive and transmit FIFOs permit efficient operation even with high
system latencies. The 21143 chip was chosen for its high performance, advanced feature set, and
wide range of avail able drivers.

The 4I60 supports full autonegot iation for automatic selection of all twisted media types. Full
duplex operation is supported on 100BaseT and 10BaseT modes. The 4I60 is a universal type
PC/104-PLUS card and will work with 3.3V and 5V bus systems. Only 5V power is required by the
4I60 (+12V is used only for the AUI connector) Unused circuitry is powered down when not needed,
in cludi ng the on card DC-DC converter. The 100BaseT interface of the PHY i s powered down when
usin g 10BaseT.

All options are software selectable except the PCI slot number. A MII compatible connector is
available for use with other media types. A socket for a 32 pin boot ROM of up to 256K bytes is
provided. 5V flash ROMs, can be used, simplifying software upgrades. Various 4I60 options are
available including a lower cost and lower power 10BaseT only model. A low cost external panel
mount transceiver option i s avail able f or 10Base2 (BNC) operation.
