Texas Instruments’ Stellaris LM4F120H5QRC microcontroller is based on an 80MHz copy of the ARM Cortex-M4F processor core with an integrated single-precision floating-point unit. It also includes 256Kbytes of Flash memory, 32Kbytes of SRAM, 2Kbytes of EEPROM, and a host of analog and digital peripherals. That’s a ton of capability packed into an incredibly small package.

TI has developed an eval board to support design-in of this microcontroller and there’s a timer on TI’s Web site that’s counting down to the day of introduction for this board, dubbed the “LaunchPad”. As of this writing, the timer’s at 20 days and counting.
As a promotion, TI is currently offering the Stellaris LaunchPad eval board for $4.99 including shipping as a pre-introductory price. The eval board includes:
- A Stellaris LM4F120H5QRC microcontroller
- An on-board, in-circuit debug interface
- A Micro-B USB interface
- A pre-loaded RGB quickstart app
- A USB and peripheral driver library
There are support and development tool chains available from:
- Keil
- Sourcery CodeBench
- IAR Tools
- CodeComposer Studio
Again, the price is $4.99 including shipping. The expected ship date is September 25 or thereabouts. You can buy as many as two at this price. Click here.
