EP7311-IB Overview


The embedded microprocessor has been packed in 256-LFBGA for convenient overseas shipping. High reliability can be achieved by using the advanced packaging method Tray. Cores/Bus width of the CPU is 1 Core 32-Bit . Understand the operating temperature around -40°C~85°C TA. In the EP7 series, it is found. A ARM7TDMI processor powers this CPU. There are SDRAM RAM controllers on this CPU. This microprocessor is equipped with an interface of DAI, IrDA, SSI, UART. As far as I/O is concerned, this CPU runs at 2.5V 2.7V 3.0V 3.3V. As far as the uPs/uCs/Peripheral ICs type is concerned, this is a MICROCONTROLLER, RISC. Use EP7311 to search for variants of the cpu microprocessor. In total, there are 256 terminations. Turning on and running the embedded microprocessor with a 2.5V voltage supply should be possible. In terms of architecture, it is a 32-Bit system. A CPU operates at a frequency of 74MHz. For information about 256 pins, please refer to the datasheet. There is a maximum supply current of 2.7V in this microprocessor. Data can be transferred over 32b bandwidths. Injection of 256 pins into the body of the embedded microprocessor is carried out. A 1-core CPU is used here. Micro processors can be used from 2.5V. There is 48kB RAM (Random Access Memory) built in. By using 27 I/Os, CPU programs transfer data.
