The MB86965B EtherCoupler
Ethernet Controller is a
high–performance, highly integrated monolithic device, a
superset of the Fujitsu MB86965A, that incorporates a
network controller with buffer management, Manchester
encoder/decoder, 10BASE–T transceiver with on–chip
transmit and receive filters, and bus interface for a
PC/XT/AT/ISA bus. New features of the MB86965B not
present in its predecessor, the MB86965A, are summarized
below. The EtherCoupler allows implementation of adapter
solutions with as few as four chips. With its optional generic
bus mode, it is suitable for use directly on a microprocessor
bus, local bus or expansion bus.
A serial EEPROM can be interfaced to the chip for storage of
Ethernet ID and configuration settings. The EtherCoupler is
designed to be configured electronically, thus eliminating
the jumpers typically used to configure system network
adapters. When either the reset pin is activated, or a
‘
software reset’ is issued by writing any value to any
on–chip address in the range x18 to x1F(hex), the
MB86965B will download three essential configuration
parameters from the EEPROM to BMPR19.
New Features of the MB86965B EtherCoupler
Full–duplex capability
External loopback mode allows testing of all 10BASE–T
interface circuits
Write support for an external Flash boot PROM
Software Reset now enables the system to fully reset and
re–initialize the controller without the need to activate the
system reset line
24 mA drive capability for IOCHRDY and IOS16 pins to
allow direct connection to the ISA bus
ADDITIONAL FEATURES
Optional, generic host interface to connect to industry–
standard microprocessor busses
Built–in interface for PC/XT
/AT
or compatible
busses
Interface to serial EEPROM for Node ID and configura-
tion storage allows construction of jumperless, electroni-
cally–configurable adapters
