MCIMX257DJM4AR2 Overview
Packed in 400-LFBGA, the microprocessor is convenient for shipping overseas. Advanced packaging method Tape & Reel (TR) is used to provide high reliability. The CPU has 1 Core 32-Bit cores/Bus width. Extended operating temperature around -20°C~70°C TA. It comes from the i.MX25 series. This CPU is cored with a ARM926EJ-S processor. This CPU uses LPDDR, DDR, DDR2 RAM controllers. To serve better this microprocessor features CAN, I2C, I2S, MMC/SD/SDIO, SAI, SPI, SSI, SSP, UART interfaces. This CPU runs I/O at 2.0V 2.5V 2.7V 3.0V 3.3V. As far as the uPs/uCs/Peripheral ICs type is concerned, this is a MICROPROCESSOR. There are 400 terminations totally. With a 1.45V voltage supply, the part should be turned on and run. It has a 32-Bit architecture. The supply voltage should not exceed 1.52V. This CPU has a wide external data Bus width of 16. The embedded microprocessor has a clock frequency of 24MHz. As specified in datasheets, the embedded microprocessor requires 1.2/1.51.8/3.3V power supplies.
