C2000 Piccolo F2807x multipoint control units (MCUs) from Texas Instruments improve execution speeds of control tasks in hybrid-electric and electric vehicles. Analog and control peripherals integrate control applications and are scalable with other MCU generations. A real-time control accelerator increases system performance and throughput, providing an additional 120 MHz of floating-point processing capability and allowing parallel math-intensive or time-sensitive signal processing tasks to run so the central processing unit (CPU) can focus on diagnostics, communications, and motion profiling. A trigonometric math unit accelerator, also integrated in the main CPU, allows the chip to execute trigonometric-based algorithms used in transforms and control functions. A flexible pulse-width modulator supports all digital power topologies to decrease digital control system complexity. Software development includes examples, header files, and application libraries.
