SoC boosts EV and HEV performance

Developers can maximise efficiency in cost-sensitive power-control applications with new additions to TIs’ C2000 Piccolo microcontroller (MCU) portfolio, says the company as it unveiled the latest additions to the portfolio.

The C2000 F28004x MCU family is optimised for power-control in cost-sensitive applications such as on-board chargers for electric vehicles (EVs), inverters for motor control, and industrial power supplies. According to Texas Instruments, the addition of this family of real-time control devices that integrate a floating-point unit, math accelerators and an optional parallel processor, boosts the performance of its 100MHz central processing unit (CPU).

Developers can reduce bill-of-material (BoM) costs while building smaller, more reliable systems, continues Texas Instruments, as the C2000 Piccolo F28004x MCUs offer system protection and new capabilities to enable development of high-performance power-control systems. The integrated analogue features include three independent 12-bit ADCs with post-processing hardware, advanced synchronisation capabilities and programmable gain amplifiers, along with a sophisticated comparator and DAC subsystem and a sigma-delta filter interface.

The C2000 F28004x MCUs have 60 per cent lower active power than previous Piccolo devices. The optional on-chip DC/DC converter reduces active power up to 70 per cent. This fourth generation of TI’s high-resolution pulse-width modulation (PWM) timer technology implements the most advanced high-frequency switching techniques for increased efficiency and power density, claims the company.

Enhanced digital and analogue crossbars combine inputs, outputs and internal resources to enable the flexibility to support control and protection mechanisms.  New capabilities include an embedded real-time analysis and diagnostic unit for enhanced debugging. There is also a high-speed serial interface to improve throughput over isolation boundaries, and flexible boot modes to give developers the ability to reduce or eliminate boot mode pins.

Production quantities of the C2000 F28004x MCUs are available in a 64-pin LQFP. Developers can evaluate the C2000 F28004x MCUs with the F280049 experimenter kit (TMDXDOCK280049M).
