The newest additions to the C2000 Piccolo microcontroller (MCU) portfolio have been unveiled by Texas Instruments (TI). With streamlined performance, the new 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.

By adding this new family of real time control devices that integrate a floating-point unit, math accelerators and an optional parallel processor, the C2000 Piccolo MCU portfolio continues to set industry standards by boosting the performance of its 100MHz Central Processing Unit (CPU).

Developers can reduce Bill-Of-Material (BOM) costs while building smaller, more reliable systems by taking advantage of the integrated analogue of the C2000 Piccolo F28004x MCUs, which offer system protection and new capabilities to enable development of high performance power-control systems.

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

Key features and benefits of the new C2000 F28004x MCUs

  • Streamlined performance and power: With 60% lower active power than previous Piccolo devices; the optional on-chip DC/DC converter reduces active power up to 70%.
  • Advanced actuation and design flexibility: 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.
  • Enhanced digital and analog crossbars: Combining inputs, outputs and internal resources enables flexibility to support control and protection mechanisms.
  • New capabilities: Embedded real time analysis and diagnostic unitenables enhanced debugging, an ultra-high speed serial interface improves throughput over isolation boundaries, and flexible boot modes give developers the ability to reduce or eliminate boot mode pins.

The new C2000 Piccolo F28004x MCU builds on the generational improvements introduced in the Delfino F2837x and Piccolo F2807x series. These new real time control solutions offer code compatibility with existing Piccolo MCUs, allowing customers to take advantage of the new family’s combination of premium performance in an affordable offering.
