Texas Instruments announced its TMS320F2806 Piccolo floating-point MCUs. These MCUs offer an enhanced math engine designed to simplify programming in real-time control applications that may require integrated communications. Developers of energy-efficient motor-control and renewable energy applications can use a single F2806x MCU to execute control loops as well as power line communications (PLC) protocols and modulation schemes. Features include a math engine comprised of 80 MHz floating-point C28x core, new Viterbi Complex Math Unit (VCU) and Control Law Accelerator (CLA) options. The VCU complex math unit provides 75 tailored math instructions to accelerate processing of communications algorithms, such as those for PLC, by a factor of up to 7X. Additional features include increased communications and throughput via USB 2.0 full-speed (host and device), CAN and direct memory access (DMA); fifteen+ MCUs provide an increased memory range of 52 KB to 100 KB RAM, 128 KB to 256 KB flash as well as options for 80- and 100-pin packages; and control-oriented peripherals such as high-resolution PWMSs (150 ps), 3 MSPS 12-bit analog-to-digital converter (ADC) and three analog comparators with 10-bit reference.
