2.1.1 Microcontroller

The F280049CPZS is a 32-bit floating-point microcontroller with 256KB Flash memory, 100KB RAM, and operates at 100 MHz. It includes advanced control peripherals, differentiated analog, and various communications peripherals. The devices has been optimized for high-performance applications and provides a low-cost system solution. For more details, see the TMS320F28004x Piccolo microcontrollers data sheet.

Most of the microcontroller's signals are routed to 0.1 inch (2.54 mm) pitch headers laid out to comply with the TI BoosterPack standards with a few exceptions. An internal multiplexer allows different peripheral functions to be assigned to each of the General-Purpose Input/Output (GPIO) pads. The multiplexing options can be found in the device-specific data sheet. When adding external circuitry, consider the additional load on the development board power rails.

The F28004x 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. The quick start application utilizes the integrated Analog-to-Digital Converter (ADC) module to sample the voltage on a pin, then output the results with the Serial Communications Interface (SCI) Universal Asynchronous Receiver/Transmitter (UART) through the Virtual COM port (VCP) of the XDS110 debug probe to a PC with a serial monitor running.
