Does such a microcontroller exist? Answered

I am looking for an easily programmed (arduino compatible preferably) chip like an atmega but with an internal 16mhz clock. does anyone know of such a thing?

More or less any micro will communicate with any other so it depends what you actually need to be "compatible"

The picaxe familly can be run at up to 30 Mhz depending on the chip - see illustration - They have shields and many accessories, easy programming in near english basic - as well as very good manuals and support and low cost - Sparkfun in the USA I think distribute them.

A lot depends on what your doing with it.

I should add that the mxx note shows the speed in mhz. so m32 is running at 32 Mhz.

A lot of the Silabs ARM and 8052 parts have a high speed internal clock. Their development kits are out of this world for price and usefulness, and include complete free toolchains, with simulators. You can also run the chip in debug mode. They are frankly, infinitely better than Arduinos, but don't have the same ecosystem. I use Silabs stuff professionally, I don't use Arduinos.

Look at Silabs EFM8 range.

Not sure any exist with a 16mhz internal oscillator. Not to mention an internal oscillator will not be accurate. It will vary based on temp which will affect how your code runs.

I can't see any reason to us an internal oscillator. If it's about board space you can get pretty small surface mount crystals and edge mount them on the board if needed. If it's a matter of cutting cost you're really not saving much dropping a crystal. You'd save more going without a solder mask or steciling on your board.
