EP7312-CR Overview
Shipping overseas is convenient since the embedded microprocessor is packed in 204-TFBGA. High reliability is achieved with advanced packaging method Tray. This CPU has 1 Core 32-Bit cores and 1 Core 32-Bit bus widths. It is important to understand the operating temperature around 0°C~70°C TA. The EP7 series contains it. The CPU is cored by a processor with a number of 0 cores. Memory controllers for this CPU are SDRAM. This microprocessor features DAI, IrDA, SSI, UART interfaces to better serve its users. This CPU runs I/O at 2.5V 2.7V 3.0V 3.3V. I would rate this as a MICROCONTROLLER, RISC for the uPs/uCs/Peripheral ICs type. Use EP7312 to search for variants of the cpu microprocessor. In total, 204 terminations have been made. Using a 2.5V voltage supply, the microprocessor should turn on and run. It has a 32-Bit architecture. There is 74MHz frequency set for the CPU. To learn about the functions of the pins 204 please refer to their datasheets. There is a maximum supply current of 2.7V in this microprocessor. For data transfer, there is 32b bandwidth available. A total of 204 pins are injected into the CPU microprocessor's body. The CPU has 1 cores. In this case, 2.5V is the starting point. It is designed with 0 RAM (Random-Access Memory). Programs on the CPU transfer data through 27 I/Os.
