1.4 Device Information
The TMS320F28P550SJ9PZ is a 32-bit floating-point microcontroller with 1088KB Flash memory, 133KB
RAM, a programmable Control Law Accelerator (CLA) for offloading tasks, and operates at 150MHz.
The TMS320F28P550SJ9PZ includes advanced control peripherals, differentiated analog, and various
communications peripherals. The device has been optimized for high-performance real-time control applications.
For more details, see the
Most of the signals of the microcontroller are routed to 0.1 inch (2.54mm) pitch headers laid out to comply
with the TI BoosterPack standards, with a few exceptions. The F28P55x internal multiplexer of the MCU allows
different peripheral functions to be assigned to each of the General-Purpose Input/Output (GPIO) pins. The
multiplexing options can be found in the device-specific data sheet. When adding external circuitry, consider the
additional load on the development board's power rails.
The F28P55x LaunchPad is factory-programmed with a quick start demo program. The quick start program
resides in the on-chip flash memory and executes each time power is applied, unless the application has been
replaced with a user program. For details on the demo program of the LaunchPad, see
