Low cost 32-bit MCUs ease development for white goods and industrial apps

C2000 Piccolo TMS320F2802x microcontrollers from Texas Instruments Incorporated bring low-cost 32-bit real-time control to applications typically unable to justify the associated cost, such as household appliances, industrial textile machines and compressors. The Piccolo MCUs offer integrated analog hardware on chip while enabling increased power efficiency and system protection. With sizes as small as 38 pins, these devices replace multiple electronic components with one chip and enable advanced power management in motor control applications.

Along with a 12-bit analog-to-digital converter (ADC), the Piccolo F2802x microcontrollers integrate analog comparators that help designers manage power stages and provide system protection in motor control and digital power systems. The internal comparators implement seamless shutdown of select pulse-width modulation channels or trigger other events, without the cost of external complicated fault management circuits.

High-resolution, enhanced pulse width modulators (ePWMs) 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.

Pricing starts at $1.50 in 1k volumes. Available in a wide variety of configurations for flexible design. Development tools include: C2000 LaunchPad, controlCARD (TMDSCNCD28027) and $79 Experimenter's Kit (TMDSDOCK28027). controlSUITE software is free and can be accessed immediately. Several motor control and digital power development kits are also available now.
