                                                ATSAMA5D27A-CU Overview
Shipping overseas is convenient since the embedded microprocessor is packed in 289-LFBGA. High reliability is achieved using advanced packaging method Tray. CPUs have 1 Core 32-Bit cores/bus width. Understand the operating temperature around -40°C~85°C TA. It comes from the SAMA5D2 series. The CPU is cored with a ARM? Cortex?-A5 processor. It has LPDDR1, LPDDR2, LPDDR3, DDR2, DDR3, DDR3L, QSPI RAM controllers. The microprocessor features interfaces I2C, SMC, SPI, UART, USART, QSPI for better service. 3.3V is the I/O speed of this CPU. You can search for variants of a microprocessor with ATSAMA5D27. CPUs operate at 500MHz Hz. For functions of 289 pins, please refer to the datasheets. In order to transfer data, there is a bandwidth of 32b. As a result of its Surface Mount mounting, this CPU is widely used in a wide variety of applications. In this case, 1.2V is the starting point. The amount of RAM (Random-Access Memory) is designed 128kB. The embedded microprocessor should not be supplied with a voltage higher than 1.32V. There should be 1.1V voltage applied to the CPU microprocessor below 1.1V. 128 I/Os are used by CPU programs to transfer data. 160kB is the size of the CPU's memory. The CPU's idle time can be determined by 6 counters. The CPU is connected to DMA, LCD, POR, PWM, WDT peripheral devices.
