EP7311-CB Product Details

EP7311-CB Overview


Shipping overseas is convenient thanks to the embedded microprocessor's packaging in 256-LFBGA. High reliability is achieved using advanced packaging method Tray. 1 Core 32-Bit cores/Bus width are present in the CPU. Identify the operating temperature around 0°C~70°C TA. In the EP7 series, it is found. The CPU is cored by a processor with a number of 0 cores. A total of SDRAM RAM controllers are used by this CPU. The microprocessor features interfaces DAI, IrDA, SSI, UART for better service. At 2.5V 2.7V 3.0V 3.3V, the CPU runs its I/O. A MICROCONTROLLER, RISC represents the uPs/uCs/Peripheral ICs type. Search EP7311 for variants of the embedded microprocessor. In total, 256 terminations have been made. Using a 2.5V voltage supply, the microprocessor should turn on and run. It is an architecture with 32 bits. CPUs operate with a frequency of 74MHz Hz. You can refer to the datasheets for the functions of 256 pins. The maximum supply current of this microprocessor is 2.7V. It is important to note that there is 32b bandwidth available for data transfer. An injection of 256 pins is performed inside the body of the micro processor. 1 cores are present in this processor. From 2.5V on, the CPU microprocessor will function. In general, RAM (Random-Access Memory) is designed with a 48kB of 0MB. A CPU program transfers data by using 27 I/Os.
