SPEAR320-2 Product Details

SPEAR320-2 Overview


Due to its 289-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 SPEAr® series. ARM926EJ-S is the processor core of this CPU. Memory controllers for this CPU are LPDDR, DDR2. Featuring CAN, I2C, IrDA, Microwire, MMC/SDIO, SPI, UART interfaces, this microprocessor can better serve you. There is 3.3V I/O running on this CPU. The type MICROCONTROLLER, RISC belongs to uPs/uCs/Peripheral ICs. SPEAR320 is a good way to search for variants of the microprocessor. Total terminations are 289. Using a 1.2V voltage supply, you should be able to operate the cpu microprocessor. 32-Bit is its architecture. A 333MHz frequency is used by the CPU. The datasheets for 289 pins provide details. To transfer data, there are 16b bandwidths available. Embedded microprocessor bodies have 289 pins injected into them. As a result of its Surface Mount mounting, this CPU is widely used in a wide variety of applications. From 1.2V onwards, the CPU microprocessor can operate. According to datasheets, the micro processor requires 1.21.83.3V power sources. There is 3.6V voltage present in the CPU core. There is 8kB RAM (Random Access Memory) built in. Users should not supply a microprocessor with more voltage than 2.5V under normalcircumstances. In order for the micro processor to work at its best, it should be fed a voltage of 1.14V. Data is transferred through 29 I/O ports by CPU programs. There is 32kB memory on the CPU. The CPU's idle time can be determined by 4 counters.
