On this basis, users can select a processor corresponding to their design and be able to test and validate the connected hardware unit as well as program Flash memories.
The microcontrollers offer an extremely good balance of connectivity, power and performance. They are mainly used in the field of industrial control, automation, process control, data collection and consumer. The processors are based on a 32-bit ARM Cortex M4 RISC architecture with clock frequencies up to 120 MHz.
They are integrated in miniaturised packages such as BGA (Ball Grid Array) with up to 157 pins, not allowing direct contacting to external instruments. Therefore, the aim of VarioTAP technology is to provide access for test, hardware debugging, Flash programming and design validation after chip mounting.
