EP7312-IB Product Details

EP7312-IB Overview


The embedded microprocessor has been packed in 256-LFBGA for convenient overseas shipping. Using advanced packaging techniques Tray, high reliability is ensured. A CPU with 1 Core 32-Bit cores and width 1 Core 32-Bit busses is used. Understand how the operating temperature around -40°C~85°C TA is determined. This is a member of the EP7 series. With a core count of ARM7TDMI, this CPU is multicore. A CPU with this architecture uses SDRAM RAM controllers. With its DAI, IrDA, SSI, UART interfaces, this microprocessor will be able to serve you better. The CPU runs at 2.5V 2.7V 3.0V 3.3V when it comes to I/O. uPs/uCs/Peripheral ICs type is MICROCONTROLLER, RISC. Use EP7312 when searching for variants of the embedded microprocessor. Overall, there are 256 terminations. The microprocessor should be turned on and run with a voltage supply of 2.5V volts. This microprocessor has an architecture of 32 bits. 74MHz Hz is the frequency at which the CPU operates. To learn about the functions of the pins 256 please refer to their datasheets. There is a maximum supply current of 2.7V in this microprocessor. Its external data bus width is 32. Micro processor body consists of 256 pins. In this case, we have a CPU with only 1 core. A 48kB amount of RAM (Random-Access Memory) is designed. There are 27 input/output (I/O) channels on the CPU that transfer data.
