Description of tms320f28027
C2000 ™ 32-bit microcontrollers are optimized in processing, sensing and driving to improve closed-loop performance in 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. C2000 product line includes Delfino ™ High performance family and piccolo ™ Entry level performance family.
F2802x Piccolo ™ Series microcontrollers are packaged with low pin count devices and combined with highly integrated control peripherals to provide powerful functions of c28x core. The code of this series of devices is compatible with the old code based on c28x, and has high analog integration.
An internal regulator enables single power rail operation. The hrpwm module is enhanced to realize double edge control (frequency modulation). An analog comparator with 10 bit internal reference is added, which can be directly routed to control PWM output. ADC can implement conversion within the fixed full scale range of 0V to 3.3V, and support the proportional operation of vrefhi/vreflo benchmarks. ADC interfaces have been optimized for low overhead and latency.
