With a packing size of 621-FBGA, FCBGA, this embedded microprocessor is ideal for international shipping. CPUs have 4 Core 64-Bit/1 Core 32-Bit cores/bus width. Be aware of the operating temperature around -40°C~105°C TA. A ARM® Cortex®-A53, ARM® Cortex®-M4 processor is present in this CPU. The CPU contains DDR3, DDR3L, LPDDR2 RAM controllers. This microprocessor is equipped with an interface of I2C, SPI, PCI, UART. 1V 1.8V 3.3V is the CPU's I/O address. I would rate this as a MICROPROCESSOR, RISC for the uPs/uCs/Peripheral ICs type. As a whole, there are 621 terminations. A 1V voltage supply should be used to turn on and run the cpu microprocessor. There is a 64-Bit architecture in it. A maximum supply current of 1.05V can be achieved by the microprocessor.
