EP7309-CVZ Overview
Packed in 208-LQFP, the microprocessor is convenient for shipping overseas. Advanced packaging method Tray is used to provide high reliability. CPUs have 1 Core 32-Bit cores/bus width. Obtain a basic understanding of operating temperature around 0°C. This is part of the EP7 series. This CPU is cored with a ARM7TDMI processor. To serve better this microprocessor features DAI, IrDA, SSI, UART interfaces. 2.5V 2.7V 3.0V 3.3V is the CPU's I/O address. The microprocessor can be searched for with EP7309 if you are looking for variants. Total terminations are 208. In the case of a 2.5V voltage supply, the embedded microprocessor should be turned on and run. 74MHz is the frequency of the CPU. Please refer to the datasheets for 208 pins functions. A maximum supply current of 2.7V is available. Generally, data transfer takes place at a rate of 32b bandwidth. 208 pins are injected into the part body. In this case, we have a CPU with only 1 core. The micro processor can function from 2.5V. There is 48kB RAM (Random Access Memory) built in. Data is transferred through 27 I/O ports by CPU programs.
