The MCF527x ColdFire Integrated Microprocessor combines high integration and low cost with a new level of performance on the popular Version 2 ColdFire core appealing to those on a tight budget.
The impressive combination of connection, protection, and peripheral selection positions the MCF527x microprocessing into cost-sensitive, power-conscious applications requiring significant control processing for file management, connectivity, data buffering, user interface, and signal processing. Additionaly,
the MCF5275 and MCF5274 are pin-to-pin compatible.
