Due to the two UARTs integrated on the E981.12, for the first time users can use microcontrollers without integrated UARTs in cost-sensitive applications. This generally results in a significant reduction of the system costs. However, if UARTs integrated in the microcontroller already exist, these can obviously continue to be used.
The E981.12 dual IO-Link master transceiver comes in a space-saving QFN44L7 package and has an input voltage range from 8 V to 32 V. The power supply and configurable current limiting of the sensors (L+) can optionally be provided through external power FETs, thus lowering power loss considerably below 100 mW per channel.
The E981.12 has a SPI interface for configuration, programming and diagnostic functions. The safety functions include, among others, over-current and short-circuit protection with configurable thresholds.
Samples and evaluation boards of the E981.12 as well microcontrollers for the control with the possibility of an easy porting of TMG's IO-Link V1.1 master stacks are available now from Gleichmann Electronics.
