SPEAR300-2 Overview
Since the microprocessor is packed in 289-LFBGA, shipping overseas is convenient. High reliability is provided by the advanced packaging method Tray. The CPU has 1 Core 32-Bit cores/Bus width. The operating temperature around -40°C~85°C TC should be understood. SPEAr? is its series number. ARM926EJ-S processors are embedded in this CPU. The CPU contains LPDDR, DDR2 RAM controllers. Microprocessors with I2C, I2S, IrDA, Microwire, MMC/SDIO, SPI, UART interfaces are designed to serve users better. 3.3V is the CPU's I/O address. uPs/uCs/Peripheral ICs type is MICROCONTROLLER, RISC. Use SPEAR300 when searching for variants of the embedded microprocessor. Total terminations are 289. Turn on the cpu microprocessor and let it run with a 1.2V voltage supply. An architecture based on 32 bits is used. At 333MHz, the CPU operates. For information about 289 pins, please refer to the datasheet. Typical Microprocessors cpu microprocessor. For data transfer, there is 16b bandwidth available. The CPU microprocessor body is injected with 289 pins. In many applications, this CPU is mounted with a Surface Mount bus. In this case, 1.2V is the starting point. The micro processor requires 1.21.83.3V power supplies according to the datasheets. 3.6V is the core voltage of the CPU. Random-Access Memory (RAM) is designed with an amount of 56kB KB. The embedded microprocessor should not be supplied with a voltage higher than 2.5V. In order for the micro processor to work at its best, it should be fed a voltage of 1.14V. By using 62 I/Os, CPU programs transfer data. The CPU has memory sized 32kB. Counters 6 indicate how busy the CPU is.
