i.MX21S
  • Not Recommended for New Designs
  • This page contains information on a product that is not recommended for new designs.

Design engineers seeking the performance of a 266 MHz Arm® CPU, but who do not require high resolution video and graphics capabilities now have a compelling new choice from NXP®. the i.MX21S applications processor.

Derived from the popular i.MX21 multimedia applications processor, the i.MX21S applications processor retains many key features, including expansion slots and several connectivity options, such as USB On-The-Go (USB-OTG) for plug-and-play connectivity. This makes it well suited for a host of cost-sensitive applications including health care devices, fire and security equipment, education products and industrial automation.
