The MCF5249 and MCF5249L microprocessors deliver a new level of performance on the popular Version 2 ColdFire core with over 125 (Dhrystone 2.1) MIPS @ 140MHz (MCF5249) and the lowest ever power consumption (1.3mW/MHz) on a ColdFire device.These highly integrated microprocessors build upon the widely used ColdFire peripheral mix by adding new audio enhancements and analog functionality, in addition to an enhanced Multiply Accumulate Unit (eMAC), large on-chip memory (96K SRAM, 8K I-Cache), and a SDRAM controller. The devices are ideal for applications requiring significant control processing for file management, data buffering, and user interface, as well as signal processing in a variety of key markets such as security, gaming, medical, and digital audio. This leading package of integration, high performance, and low power consumption allows fast time to market through access to high quality software modules, easy code reuse, and extensive third party tool support.
