NXP's Arm9™ based i.MX257 applications processor targets consumer and industrial applications that
require data acquisition or need greater levels of user interaction.
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
