TMS320F28051PNT

The C2000 real-time control MCUs are optimized for processing, sensing, and driving, which can 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, as well as sensing and signal processing. The C2000 series includes high-performance MCUs and entry-level performance MCUs. The F2805x series of microcontrollers (MCUs) power the C28x core and the CLA coupled with highly integrated control peripherals in devices with fewer pins. The code of this series of devices is compatible with legacy C28x-based code while offering high analog integration. An internal voltage regulator enables single power rail operation. An analog comparator with a 6-bit internal reference is added and can control the PWM output through direct connection. The ADC can perform conversions within a fixed full-scale range of 0V to 3.3V and supports the proportional operation of VREFHI/VREFLO references. The ADC interface is optimized for low overhead and latency. The analog front end (AFE) contains up to seven comparators, up to three integrated DACs, a VREFOUT buffered DAC, up to four PGAs, and up to four digital filters. The PGA can amplify the input signal in three discrete gain modes. The actual number of AFE peripherals will depend on the number of TMS320F2805x devices.
