Pin Number
Pin Name
Type
Pin Function
15
SRDYN
Opu
Synchronous Ready Not
Ready signal to interface with synchronous bus for both EISA-like and VLBus-like extend
accesses.
For VLBus-like mode, the falling edge of this signal indicates ready. This signal is
synchronous to the bus clock signal BCLK.
For burst mode (32-bit interface only), the KSZ8841M drives this pin low to signal wait
states.
16
INTRN
Opd
Interrupt
Active Low signal to host CPU to indicate an interrupt status bit is set, this pin need an
external 4.7K pull-up resistor
17
LDEVN
Opd
Local Device Not
Active Low output signal, asserted when AEN is Low and A15-A4 decode to the
KSZ8841M address programmed into the high byte of the base address register. LDEVN
is a combinational decode of the Address and AEN signal.
18
RDN
Ipd
Read Strobe Not
Asynchronous read strobe, active Low.
19
EECS
Opu
EEPROM Chip Select
This signal is used to select an external EEPROM device.
20
ARDY
Opd
Asynchronous Ready
ARDY may be used when interfacing asynchronous buses to extend bus access cycles. It
is asynchronous to the host CPU or bus clock. this pin need an external 4.7K pull-up
resistor.
21
CYCLEN
Ipd
Cycle Not
For VLBus-like mode cycle signal; this pin follows the addressing cycle to signal the
command cycle.
For burst mode (32-bit interface only), this pin stays High for read cycles and Low for write
cycles.
22
NC
Opd
No Connect
23
DGND
Gnd
Digital IO ground
24
VDDCO
P
1.2V digital core voltage output (internal 1.2V LDO power supply output), this 1.2V output
pin provides power to VDDC, VDDA and VDDAP pins. It is recommended this ball should
be connected to 3.3V power rail by a 100 ohm resistor for the internal LDO application.
Note: Internally generated power voltage. Do not connect an external power supply to this
pin. This pin is used for connecting external filter (Ferrite bead and capacitors).
25
VLBUSN
Ipd
VLBus-like Mode
Pull-down or float: Bus interface is configured for synchronous mode.
Pull-up: Bus interface is configured for 32-bit asynchronous mode or EISA-like burst
mode.
26
EEEN
Ipd
EEPROM Enable
EEPROM is enabled and connected when this pin is pull-up.
EEPROM is disabled when this pin is pull-down or no connect.
27
P1LED3
Opd
Port 1 LED indicator
See the description in pins 3, 4, and 5.
28
EEDO
Opd
EEPROM Data Out
This pin is connected to DI input of the serial EEPROM.
29
EESK
Opd
EEPROM Serial Clock
A 4
s (OBCR[1:0]=11 on-chip bus speed @ 25 MHz) or 800 ns (OBCR[1:0]=00 on-chip
bus speed @ 125 MHz) serial output clock cycle to load configuration data from the serial
EEPROM.
