FEATURES
The M52221DEMO is a low-cost development board for the Freescale MCF52221 ColdFire
microcontroller. Application development is quick and easy with the included DB9 serial cable,
integrated BDM, and USB cable. A 128 MB flash-drive and 6-in-1 USB cable provide support
for the integrated USB PHY. CodeWarrior Development Tools provide application develop-
ment and debug support. The integrated BDM allows easy application development and de-
bugging. An optional BDM port compatible with standard ColdFire BDM / JTAG interface ca-
bles and hosting software is also provided but not installed.
