Stellaris® LM3S9B96开发板
The Stellaris® LM3S9B96 Development Board provides a platform for developing systems around the advanced capabilities of the LM3S9B96 ARM® Cortex™-M3-based microcontroller.
The LM3S9B96 is a member of the Stellaris Tempest-class microcontroller family. Tempest-class devices include capabilities such as 80 MHz clock speeds, an External Peripheral Interface (EPI) and Audio I2S interfaces. In addition to new hardware to support these features, the DK-LM3S9B96 board includes a rich set of peripherals found on other Stellaris boards.
The development board includes an on-board in-circuit debug interface (ICDI) that supports both JTAG and SWD debugging. A standard ARM 20-pin debug header supports an array of debugging solutions.
The Stellaris® LM3S9B96 Development Kit accelerates development of Tempest-class microcontrollers. The kit also includes extensive example applications and complete source code.
