EP9307-CR Overview
Due to its 272-LFBGA packaging, it is convenient to ship overseas. High reliability can be achieved by using the advanced packaging method Tray. Cores/Bus width of the CPU is 1 Core 32-Bit . Obtain a basic understanding of operating temperature around 0°C. From the EP9 series. ARM920T is the processor core of this CPU. Memory controllers for this CPU are SDRAM. Featuring AC'97, I2S, IrDA, SPI, UART interfaces, this microprocessor can better serve you. There is 1.8V 3.3V I/O running on this CPU. The type MICROPROCESSOR, RISC belongs to uPs/uCs/Peripheral ICs. EP9307 is a good way to search for variants of the microprocessor. Total terminations are 272. Using a 1.8V voltage supply, you should be able to operate the cpu microprocessor. 32-Bit is its architecture. A 200MHz frequency is used by the CPU. The datasheets for 272 pins provide details. To transfer data, there are 32b bandwidths available. Embedded microprocessor bodies have 272 pins injected into them. It has 1 cores. From 1.8V onwards, the CPU microprocessor can operate. There is 4B RAM (Random Access Memory) built in.
