TMS320F28021PTS

C2000 32-bit microcontrollers are optimized for processing, sensing, and driving to improve the closed-loop performance of real-time control applications such as industrial motor drives, photovoltaic inverters and digital power supplies, electric vehicles and transportation, motor control, and sensing and signal processing. The F2802x microcontroller series offers the power of the C28xx core, combined with highly integrated control peripherals in low-pin-count devices. The code of this series of devices is compatible with the legacy code based on C28x and has high analog integration. The internal regulator enables single power rail operation. The HRPWM module is enhanced to enable bilateral edge control (frequency modulation). An analog comparator with a 10-bit internal reference is added, which can be directly routed to control the PWM output. The ADC can perform conversions in a fixed full-scale range of 0V to 3.3V and supports the proportional operation of the VREFHI/VREFLO reference. The ADC interface is optimized for low overhead and latency.
