A Seamless Migration Path Protects Your

Technology Investment

By leveraging your existing development tools

and software, the MCF5249 protects the

resources you’ve already invested in 68K and

ColdFire microprocessor technology and

training. For example, when you move from 68K

to ColdFire microprocessors, you can use code

translation and emulation tools, free of charge to

registered users, to modify and reuse 68K

assembly code.

The 100-percent synthesizable ColdFire Family

secures your investment in technology and

training well into the future. Even better, the

ColdFire family of microprocessors, including

the MCF5249, gives you the freedom to

experiment with powerful capabilities for

visionary electronic products, without

sacrificing system costs or time to market.
