Levii is a small and easy-to-use level shifter for the I2C bus. This is indispensable in applications where two I2C buses have to communicate with different bus voltage levels.
Additionally, Levii offers two bi-directional pins for general purposes including a second I2C bus.
Features:
- Full bi-directional level shifting including stretching and multimaster arbitration
- Four channels: SDA, SCL plus two additional bi-directional pins
- I2C range of 1,8 V up to 5,5 V
- No external supply required; Levii uses the voltage on the VCC lines of the connected I2C buses
- Transmissions specified up to 800 kbit/s SCL-frequency
Check the product page for more details. Levii is available for 190 Euro.
We have now complemented our I2C product line with Optii, a multi-purpose I2C galvanic isolation and level shifting device. Optii comes in a solid housing and provides substantial protection against problems related to differing electrical potentials. Features:
- Provides galvanic isolation for the I2C bus
- Provides an integrated level shifter for voltages between 1.5 V and 5.5 V
- Provides support for unidirectional test pins which are also isolated
Check the product page for more details. Optii is available for 695 Euro.
We are proud to announce the availability of I2C Slave support for Tracii XL with the latest release of I2C Studio. This feature is free for all Tracii XL users with a valid service contract. With this new functionality you can instruct Tracii XL to act as an I2C slave at a configurable address. Both, read and write operations are possible. The behaviour is identical to a typical I2C memory i.e. combined transfers are supported. Note that absolutely no hardware modification is necessary to enable the slave mode. In addition to this generic I2C RAM behaviour telos can implement custom specific device simulations for more complex ICs like tuners, sensors, video processors etc. Please ask for details.
Starting with I2C Studio release 1.9 it is possible to share and access telos I2C interfaces via the Internet.
- Each application can control I2C interfaces all over the world.
- Each I2C interface can be shared by several applications.
- Of course this is valid for user applications written with our I2C framework, too.
