EP7312-IV Overview


The microprocessor is conveniently packaged in 208-LQFP, making it easy to ship internationally. 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. K-40°C~85°C TAw what the operating temperature is around -40°C~85°C TA. EP7 is its series number. The CPU is cored with a ARM7TDMI processor. Memory controllers for this CPU are SDRAM. With its DAI, IrDA, SSI, UART interfaces, this microprocessor will be able to serve you better. In this CPU, I/O is set to 2.5V 2.7V 3.0V 3.3V. In terms of uPs and uCs as well as peripheral ICs, this is a MICROCONTROLLER, RISC. Try searching for variants of the cpu microprocessor with EP7312. To date, there have been 208 terminations. When the voltage supply is 2.5V, the cpu microprocessor should be powered on and run. It is an architecture with 32 bits. A CPU operates at a frequency of 74MHz. 2.7V is its maximum supply current. An external data bus width of 32 is available on this CPU. There are 208 pins injected into the embedded microprocessor body. The CPU has 1 cores. A 48kB amount of RAM (Random-Access Memory) is designed. A CPU program transfers data by using 27 I/Os.
