Power Supply for A/D converter
The power supply for the A/D converter must not be
turned on before the power supply VCC.
If the A/D converter is not used, connect the pins as
follows: AVCC = AVREF = VCC, AVSS = VSS.
Input / output pins
All input and output pins for digital signals are active
low. This means for input pins, that inverted pin level
is mapped to PDO. For output pins the inverted byte
value from received PDO is written to the ouput pins.
Additional inverting capabilities are supported.
Pull up/down resistors
The CO4011 does not support internal pull up/down
resistors. Use external components where needed.
Pin Description
All input / output pins are high impedance during
reset. The CO4011 does not support internal pull
up/down resistors. Use external components where
needed. All input pins have Schmitt trigger
characteristics. See chapter “Typical Applications”
for additional information.
IN0 to IN11: Digital or analog input pins
The function of IN0 to IN7 depends on setting of
configuration bits CFG0 to CFG2. See also chapter
“Mapping I/O to Object Dictionary” for details.
Note: Digital input pins are active low. This
means that digital input pins are mapped with
inverted values to transmit PDO data.
All digital inputs use internal Schmitt trigger circuits.
The CO4011 provides optional input inverters and
internal noise filtering for all inputs with individual
setting for each channel. See chapter “Object
Dictionary” for details.
OUT0 to OUT12: Digital output pins
All output pins have high current drive capabilities of
approximate 4 mA for direct interfacing for
optocouplers without additional drivers.
Note: Digital output pins are active low. This
means that received output data from PDO is
written with inverted values to output pins.
The CO4011 provides optional output inverters with
individual setting for each channel. See chapter
“Object Dictionary” for details.
IO0 to IO7: Digital input or output pins
The function of IO0 to IO7 depends on the settiong
of CFG2. See also chapters “Device Configuration”
and “Mapping I/O to Object Dictionary” for details.
For IOx the description of INx or OUTx is valid,
dependant to CFG2 setting.
CF: Filter Capacitor input
For correct operation of the CO4011 a ceramic
capacitor of 100 nF or 220 nF must be connected
between Pin 57 (CF) and VSS. Place this component
as close as possible to the CO4011.
X0, X1: Crystal oscillator input
Connect a crystal of 4 MHz between X0 and X1. Use
additional ceramic capacitors of 22 pF between X0
and X1 to VSS.
