Private Data Bus
This is the data bus for the static RAM, the Boot PROM,
and the Address PROM.
Input/Output
SLEEP
Sleep
When
SLEEP
input is asserted (active LOW), the
PCnet-ISA controller performs an internal system reset
and proceeds into a power savings mode. All outputs
will be placed in their normal reset condition. All PCnet-
ISA controller inputs will be ignored except for the
SLEEP
pin itself. Deassertion of
SLEEP
results in
wake-up. The system must delay the starting of the net-
work controller by 0.5 seconds to allow internal analog
circuits to stabilize.
Input
SMA
Shared Memory Architecture
This pin is sampled after the hardware RESET se-
quence. The pin must be pulled permanently LOW for
operation in the shared memory mode.
Input
SMAM
Shared Memory Address Match Input
This pin indicates an access to shared memory when
active. The type of access is decided by
MEMR
or
MEMW
.
SROE
Static RAM Output Enable
This pin directly controls the external SRAM’s
OE
pin.
Output
SRWE
Static RAM Write Enable
This pin directly controls the external SRAM’s
WE
pin.
Output
TE
Test Enable
This pin is for factory use only. It has a default value of
HIGH if left unconnected. It is strongly recommended
that this pin always be connected to V
DD
.
Input
XTAL1
Crystal Connection
The internal clock generator uses a 20 MHz crystal that
is attached to pins XTAL1 and XTAL2. Alternatively, an
external 20 MHz CMOS-compatible clock signal can be
used to drive this pin. Refer to the section on External
Crystal Characteristics for more details.
Input
XTAL2
Crystal Connection
The internal clock generator uses a 20 MHz crystal that
is attached to pins XTAL1 and XTAL2. If an external
clock is used, this pin should be left unconnected.
