Hi Orville,
The answer really depends on which CodeWarrior product you plan to use within the suite, because the feature sets vary from product to product. You can find a table listing what features are included in each suite level here. This list is divided by product, so just find the tab for the one you'll be using.
With an annual subscription, you can expect all of the features of the tool to stop working at the end of the subscription period. The exception is, if there is a free Special Edition for the product you'll be using, the features that are included in the Special Edition will work after your annual subscription expires.
You'll see on the table that there is a Flash Programmer Only tool within the Basic Suite for PowerQUICC, QorIQ, and MobileGT. The code size that can be programmed is not limited in each of these products. In all other products, the code size supported by the Flash Programmer is the same as the code size supported by the Debugger in each suite level.
If you still have questions after reviewing the table, please let me know which product you plan to use, and I'll look at it specifically to try to help you out.
