USA - Piccolo microcontrollers from Texas Instruments (www.ti.com) bring 32-bit real-time control to applications typically unable to justify the associated cost, such as household appliances, industrial textile machines and compressors. The C2000 Piccolo TMS320F2802x microcontrollers offer significant integrated analog hardware on chip while enabling increased power efficiency and system protection. With sizes as small as 38 pins, these devices feature architectural advancements and enhanced peripherals, replacing multiple electronic components with one chip and enabling advanced power management in motor control applications.
Increase system protection Along with a 12-bit analog-to-digital converter (ADC), the Piccolo F2802x microcontrollers also integrate analog comparators which help designers seeking to manage power stages and provide system protection in motor control and digital power systems. The internal comparators enable designers to implement seamless shutdown of select pulse-width modulation channels or trigger other events, without the cost of external complicated fault management circuits.
Add power conversion and cost-effective battery charging Also integrated on the Piccolo F2802x microcontrollers are high-resolution, enhanced pulse width modulators (ePWMs) which provide effective power conversion, along with motor control, using one device. Developers can add cost-effective battery charging via solar or induction to their motor control applications, as well as active power factor correction (PFC) with sufficient performance to implement internal slope compensation with peak current mode control (PCMC) of a secondary DC-DC conversion stage.
Features and benefits of Piccolo F2802x microcontroller systems: • High-performance and low power, starting at $1.50, 32-bit CPU (TMS320C28x): Static CMOS technology features a 60 MHz (16.67-ns cycle time) and single 3.3V power supply in a 38-pin package, to help integrate motor and real-time digital control.
• High integration of analog: 12-bit ADC, ePWMs, internal comparators, Flash and RAM memory to add system protection; reduce number of electronic components for smaller, faster power electronics and reduced materials cost.
