EP7309-CBZ Product Details

EP7309-CBZ Overview


Since the microprocessor is packed in 256-LFBGA, shipping overseas is convenient. High reliability is achieved by using advanced packaging methods Tray. This CPU has 1 Core 32-Bit cores and 1 Core 32-Bit bus widths. K0°C~70°C TAw what the operating temperature is around 0°C~70°C TA. In the series EP7, it is found. ARM7TDMI processors are embedded in this CPU. Microprocessors with DAI, IrDA, SSI, UART interfaces are designed to serve users better. 2.5V 2.7V 3.0V 3.3V is the I/O speed of this CPU. Use EP7309 to search for variants of the cpu microprocessor. The total number of terminations is 256. Turning on and running the embedded microprocessor with a 2.5V voltage supply should be possible. A CPU operates at a frequency of 74MHz. Detailed functions for 256 pins can be found in the datasheets. 2.7V is its maximum supply current. For data transfer, there is 32b bandwidth available. Injection of 256 pins into the body of the embedded microprocessor is carried out. A 1-core CPU is used here. In this case, 2.5V is the starting point. In this case, the amount of RAM (Random-Access Memory) is set to 48kB. In CPU programs, data is transferred by 27 I/Os.
