MCIMX251AJM4AR2 Overview
Shipping overseas is convenient since the embedded microprocessor is packed in 400-LFBGA. In order to provide high reliability, advanced packaging method Tape & Reel (TR) is used. Cores/Bus width is 1 Core 32-Bit. Recognize operating temperatures around -40°C~85°C TA. The cpu microprocessor belongs to the i.MX25 series. The CPU is cored with a ARM926EJ-S processor. The CPU uses LPDDR, DDR, DDR2 RAM controllers. This microprocessor features interfaces CAN, I2C, I2S, MMC/SD/SDIO, SAI, SPI, SSI, SSP, UART. In this CPU, I/O is set to 2.0V 2.5V 2.7V 3.0V 3.3V. In terms of uPs and uCs as well as peripheral ICs, this is a MICROPROCESSOR. The microprocessor can be searched for with MCIMX251 if you are looking for variants. In total, there are 400 terminations. When the voltage supply is 1.45V, the cpu microprocessor should be powered on and run. In terms of architecture, it is a 32-Bit system. It can supply a maximum current of 1.52V. 24MHz is the microprocessor's clock frequency. According to its datasheet, this micro processor requires 1.2/1.51.8/3.3V power supplies.
