EP7312-IBZ Product Details

EP7312-IBZ Overview


The embedded microprocessor ships overseas conveniently packed in 256-LFBGA. A high level of reliability is provided by using an advanced packaging method Tray. In the CPU, there are 1 Core 32-Bit cores and 1 Core 32-Bit bus width. It is important to understand the operating temperature around -40°C~85°C TA. EP7 is its series number. Core-wise, this CPU has a ARM7TDMI processor. It has SDRAM RAM controllers. A DAI, IrDA, SSI, UART interface has been added to this microprocessor in order to serve the user better. As far as I/O is concerned, this CPU runs at 2.5V 2.7V 3.0V 3.3V. There is MICROCONTROLLER, RISC MICROCONTROLLER, RISC in the uPs, uCs, or peripheral ICs categories. To find variants of the microprocessor, try searching with EP7312. A total of 256 terminations have been recorded. Turn on the cpu microprocessor and let it run with a 2.5V voltage supply. There are 32 bits in its architecture. 74MHz is the frequency of the CPU. 256 pin functions are described in the datasheets. With a maximum supply current of 2.7V, it has a maximum power consumption. Data transfer has 32b bandwidths. Injecting pins into the embedded microprocessor body results in 256 pins. There is only 1 core in this processor. Micro processors can be used from 2.5V. It is designed to have RAM (Random-Access Memory) of 48kB. CPU programs transfer data via 27 I/Os.
