1.3 Specification

When TIOL221 is connected to an IO-Link controller through a three-wire interface, the controller can initiate communication and exchange data with a remote node with the TIOL221 IO-Link transceiver acting as a complete physical layer for the communication.

The TIOL221EVM can be directly mated with many compatible TI microcontrollers, or connected to any other board through the interface headers. Standalone evaluation of the TIOL221 using standard test equipment is also possible with the TIOL221EVM.

The TIOL221 can operate in two modes: pin-mode or SPI mode. When the SPI/PIN pin is low, the device operates in pin-mode. When the SPI/PIN pin is high, the device operates in SPI mode. Placing a shunt jumper on header J9 connects the SPI/PIN to GND holding the pin low and causing the device to operate in pin-mode. Likewise, not connecting a shunt jumper on header J9 connects the SPI/PIN to VOUT through a pull-up resistor causing the device to operate in SPI mode.
