The above mentioned programmable ADC features can be configured by the SoC via a serial peripheral interface (SPI). The ADC-frontend is available in a compact 9-mm by 9-mm QFN package.
As the name indicates the TDA3x is a 3rd generation SoC family developed for Driver Assistance applications. The family is designed from ground up with functional safety and ISO 26262 in mind and is available in different configurations and speed grades. The TDA3xR members of TDA3x family are most suited for Radar applications, as the ‘R’ indicates. The designator ‘x’ is a placeholder for various speed grades allowing a scalable implementation of radar sensors. The TDA3x family comprises a heterogeneous combination of processing elements optimized for the different software tasks. A dual Cortex-M4 sub-system, an Embedded Vision/Vector Engine (EVE) sub-system and up to two C66x floating point DSP sub-systems allow a power efficient implementation of the radar signal processing steps. EVE is a RISC controller with a vector coprocessor that is optimized for high throughput, high processing performance at a low power footprint. It can conduct in real time all range and Doppler FFTs as well as perform digital beam forming for multiple beams. In addition, EVE can re-sort the channel-interleaved ADC data and perform the parity check on the fly at a very low additional load.
