PIN NAME
PIN DESCRIPTION
1
41
MODE
Mode input. Used to select between Synchronous Self Clocking (MODE = 1) or Synchronous Ex-
ternal Clocking (MODE = 0) for the Serial Port.
2
42
SCLK
Serial interface clock. Synchronizes serial data transfers. Data is input on the rising edge and out-
put on the falling edge.
3
43
SDO
Serial Data Out. Serial data is read from this line when using a 3-wire serial protocol such as the
Motorola Serial Peripheral Interface.
4
44
SDIO
Serial Data IN or OUT. This line is bidirectional programmable and interfaces directly to the Intel
Standard Serial Interface using a 2-wire serial protocol.
5
1
OSC
1
Oscillator clock input for the device. A crystal connected between OSC
1
and OSC
2
will provide a
clock to the device, or an external oscillator can drive OSC
1
. The oscillator frequency should be
3.6864MHz to maintain Line Noise Rejection.
6
2
OSC
2
DV
DD
DGND
Used to connect a crystal source between OSC
1
and OSC
2
. Leave open otherwise.
Positive Digital supply (+5V).

EOS
Logical channel count output (LSB).
36
35
Logical channel count output.
37
36
Logical channel count output (MSB).
38
37
End of scan output. Signals the end of a channel scan (all active channels have been converted)
and data is available to be read. Remains low until data RAM is read.
39
38
RSTI/O
I/O reset (active low) input. Resets serial interface state machine only.
40
40
CS
Active low chip select pin. Used to select a serial data transfer cycle. When high the SDO and
SDIO pins are three-state.
