NXP | MCIMX257DJM4A

The i.MX257 integrates all features of the i.MX253 and adds a CMOS sensor interface for data input, and a touchscreen controller that lets the user interact with the device through the display enabling “smart touch”. Extra connectivity features such as Controller Area Network (CAN) and Smartcard provide endless possibilities for building plugged-in or portable, connected devices.

With its high level of integration and connectivity options, and low-power technology, the i.MX257 is ideal for building applications including “smart touch” HMI, factory automation, and data acquisition devices.
