The VarioTAP model contains all relevant access information for the respective target processor. Based on this, users can select the processor and then test and validate connected hardware units and program Flash memories.
The TI microcontrollers are designed for safety-critical transport applications. Main application fields of the processor family are automotive, railway technology and aviation. The processors are based on a 32-bit ARM Cortex R4F RISC architecture with clock frequencies up to 160MHz and are integrated into miniaturised housings as nFPGA (new Fine Pitch Ball Grid Array) with up to 337 pins.
Designs of this type do not allow direct contacting to external instruments. The aim of VarioTAP is to provide design-integrated tools for test, hardware debug, Flash programming and design validation after chip mounting.
