XA Zynq-7000 SoC First Generation Architecture

The XA Zynq™-7000 Automotive family is based on the Xilinx®SoC architecture.These products integrate a feature-rich dual-core ARM®Cortex™-A9 based processing system(PS)and 28 nm Xilinx programmable logic(PL)in a single device.The ARM Cortex-A9 CPUs are the heart of the PS and also include on-chip memory,external memory interfaces,and a rich set of peripheral connectivity interfaces.This highly integrated,flexible,and power-optimized solution is ideal for high computationally intensive and performance demanding applications.The automotive family focuses on automotive applications and consists of the Z-7010,Z-7020,and Z-7030 devices.
