2.3.3 TMS320F28023

The Piccolo F2802x family of microcontrollers provides the power of the C28x core coupled with highly integrated control peripherals in low pin-count devices. This family is code-compatible with previous C28x based code, and also provides a high level of analog integration. The internal comparators and high resolution PWM signals are both utilized to implement a very high speed LED driver. This microcontroller, when combined with the DLP3030-Q1 chipset, can support 1-µs long LED pulses and 10-ns rise and fall times required by the 5000:1 dimming ratio.

Note:

The TMS320F280023 MCU is recommended for new designs. This product is from the latest generation of C2000™ real-time MCUs with enhanced features and performance at a lower cost structure. Refer to the TMS320F2802x/TMS320F2803x to TMS320F28002x Migration Overview application report for a list of differences between the two devices.
