MCIMX257CJM4AR2 Overview
The microprocessor is convenient for international shipping since it is packaged in 400-LFBGA. The packaging method Tape & Reel (TR) provides high reliability. There are 1 Core 32-Bit cores per bus width on the CPU. The operating temperature around -40°C~85°C TA should be understood. This is part of the i.MX25 series. The CPU is powered by a ARM926EJ-S core. There are LPDDR, DDR, DDR2 RAM controllers on this CPU. This microprocessor features CAN, I2C, I2S, MMC/SD/SDIO, SAI, SPI, SSI, SSP, UART interfaces to better serve its users. The CPU runs I/O at 2.0V 2.5V 2.7V 3.0V 3.3V. uPs/uCs/Peripheral ICs are a MICROPROCESSOR. To date, there have been 400 terminations. You should be able to turn on and run the embedded microprocessor with a voltage supply of 1.45V. An architecture based on 32 bits is used. A maximum supply current of 1.52V is available. With a width of 16, this CPU has a wide external data bus. There is a clock frequency of 24MHz on the microprocessor.
