MCF5225x Embedded Controllers

Digi-Key introduces Freescale's MCF5225x family of ColdFire®
embedded controllers

MCF5225x Embedded ControllersFreescale's MCF5225x family consists of highly integrated devices with on-chip USB, Ethernet, CAN and encryption functions. The MCF5225x family is based on a 32-bit ColdFire® core with up to 80 MHz core frequency, 512 KB flash and 64 KB SRAM. The external bus interface provides flexibility to add additional memory or simple peripherals. These and other features make the MCF5225x devices ideal for industry and health care applications that require a broad range of connectivity peripherals and high performance.

The MCF5225x family is also easy to use. Freescale provides a comprehensive suite of development tools and software to help developers design quickly and easily.
