SPEAR320-2 Overview
Since the microprocessor is packed in 289-LFBGA, shipping overseas is convenient. High reliability can be achieved by using the advanced packaging method Tray. There are 1 Core 32-Bit cores per bus width on the CPU. Identify the operating temperature around -40°C~85°C TC. This is a member of the SPEAr? series. The CPU is cored with a ARM926EJ-S processor. It has LPDDR, DDR2 RAM controllers. This microprocessor has CAN, I2C, IrDA, Microwire, MMC/SDIO, SPI, UART interfaces to serve you better. I/O is run at 3.3V on this CPU. I would rate this as a MICROCONTROLLER, RISC for the uPs/uCs/Peripheral ICs type. Use SPEAR320 when searching for variants of the embedded microprocessor. There are 289 terminations totally. You should be able to turn on and run the embedded microprocessor with a voltage supply of 1.2V. It is an architecture with 32 bits. At 333MHz, the CPU operates. 289 pin functions are described in the datasheets. An example of a Microprocessors embedded microprocessor. It is important to note that there is 16b bandwidth available for data transfer. Micro processor body consists of 289 pins. There are many applications for this CPU, since it is Surface Mount mounted. From 1.2V, the micro processor can be used. It is specified in the datasheet that this micro processor requires 1.21.83.3V power supplies. There is 3.6V voltage at the CPU core. In this case, the amount of RAM (Random-Access Memory) is set to 8kB. normal operation of the microprocessor should not require the device to be powered by a voltage higher than 2.5V. It is recommended that the lowest voltage be fed to the micro processor is 1.14V. CPU programs transfer data via 29 I/Os. 32kB bytes of memory are allocated to the CPU. 4 counters are used to help tell how busy the CPU is.
