EP7312-CBZ Overview


Due to its 256-LFBGA packaging, it is convenient to ship overseas. Advanced packaging method Tray is used to provide high reliability. A CPU with 1 Core 32-Bit cores and width 1 Core 32-Bit busses is used. Recognize operating temperatures around 0°C~70°C TA. A EP7 series item. The CPU is cored by a processor with a number of 0 cores. Memory controllers for this CPU are SDRAM. This microprocessor is equipped with an interface of DAI, IrDA, SSI, UART. 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. The microprocessor can be searched for with EP7312 if you are looking for variants. As a whole, there are 256 terminations. Using a 2.5V voltage supply, you should be able to operate the cpu microprocessor. It is an architecture with 32 bits. CPUs operate at 74MHz Hz. To learn about the functions of the pins 256 please refer to their datasheets. A maximum supply current of 2.7V is available. Data can be transferred over 32b bandwidths. 256 pins are injected into the part body. There is only 1 core in this processor. As of 2.5V, the CPU microprocessor is capable of functioning. RAM (Random Access Memory) is designed to be 48kB. A CPU program transfers data by using 27 I/Os.
