EM043C is a small random number module that includes a processor to facilitate easy integration into your project. The output is conveniently formatted according to your specification including serial port, SPI (master or slave unit), or I2C. Parallel output is also possible using a handshake protocol. Pins may tri-state when not in active use. Test pins may optionally be included for analogue noise signal, digital sampled unprocessed random numbers, logic self-test signal, or a combination of these.

The price tag is for a license solution, where the customer supply all components, mount the components and download software to the processor(s).
We include schematics and also a layout. For adjustments and customer specific software we add a fee for the development time. The binary and the software source code is included.

The paid license may be applied to several products, but is restricted to a single customer.
