MCIMX257CJM4A

The i.MX25 series Applications Processor extends ARM® ARM9™ core-based portfolio and introduces several key new features such as DDR2, two embedded USB PHYs, 3.3 V I/O support, three general-purpose 12-bit ADCs and a touchscreen controller that allows customers to reduce their overall system bill of materials cost. In addition, the i.MX25 continues to make the industrial and general embedded market a key focus of i.MX with the integration of 10/100Mbps Ethernet MAC, SD/SDIO/MMC connectivity, up to SVGA (800 x 600) resolution TFT LCD support, camera sensor interface and 400MHz CPU speed grade. Improving on the strength of previous i.MX platforms, the i.MX25 applications processor provides additional tamper detection security that monitors and helps prevent system integrity attacks from hackers, making it the right choice for any type of secure device, whether it's a wired or wireless payment terminal (POS) or secure residential gateway for smart metering.
