Aiming to boost performance in EV/HEVs, grid infrastructure, and industrial applications, Texas Instruments has added new Piccolo microcontrollers (MCUs) in its C2000 Piccolo MCU portfolio. The new C2000 F28004x MCUs are optimized for power-control in cost-sensitive applications such as on-board chargers for electric vehicles (EVs), inverters for motor control, and industrial power supplies.

The integrated analog of the MCUs help developers reduce bill-of-material (BOM) costs while building smaller, more reliable systems.  The MCUs also claim a 60 percent lower active power than previous Piccolo devices.

These real-time control devices integrate a floating-point unit, math accelerators and an optional parallel processor, to boost the performance of its 100-MHz central processing unit (CPU).

The integrated analog features include three independent 12-bit analog-to-digital converters (ADCs) with post-processing hardware, advanced synchronization capabilities and programmable gain amplifiers, along with a sophisticated comparator and digital-to-analog converter subsystem and a sigma-delta filter interface.


The embedded real-time analysis and diagnostic unit enables enhanced debugging, an ultra-high-speed serial interface improves throughput over isolation boundaries, and flexible boot mode gives developers the ability to reduce or eliminate boot mode pins, according to TI.

The F280049 experimenter kit (TMDXDOCK280049M) is available for US$209.00.

Production quantities of the C2000 F28004x MCUs are available in a 64-pin LQFP package, starting at US$4.85 in 1,000-unit quantities.
