How to maximize efficiency in your power control application?


I’m excited to share with you that TI has just released to production the first package option in the new Piccolo™ F28004x microcontroller (MCU) series. What’s great about the new F28004x MCU is that it takes all of the amazing performance and peripheral improvements of the flagship Delfino™ F2837x MCU and makes them available in a Piccolo product, with optimized performance, smaller memory and packages, and lower prices.

We optimized the F28004x for power control applications, which is the core business for C2000™ MCUs. This means:

  • 100MHz performance, with a 100MHz parallel improved control law accelerator (CLA) option.
  • Floating-point unit, trigonometric math unit and Viterbi complex-unit performance accelerators.
  • 256KB and 128KB flash memory options.
  • 100KB of full-speed random access memory (RAM).
  • Flexible timers: fourth-generation enhanced pulse-width modulator (ePWM) modules with 150 ps resolution, complex waveform generation and synchronization capability.
  • Three high-performance analog-to-digital converters (ADCs) with a post-processing block, programmable gain amplifiers and a flexible comparator subsystem.

All at an attractive price point starting at US$4.85 in 1,000-unit quantities.

 

Thanks to the latest process technology, F28004x MCUs use 60% less active power than the equivalent F2806x series. New features include:

  • An optional DC/DC converter for >70% less active power.
  • A new fast serial interface to enable >200Mbps transfers and lower costs for communications over isolation boundaries.
  • Flexible boot modes to reduce or eliminate the use of boot-mode pins.
  • An embedded real-time analysis and diagnostic (ERAD) unit to enhance debugging and in-system analysis capability.

Table 1 lists the configuration options for the F28004x.

Future software releases will enable extra features for InstaSPIN-FOC™ motor control solutions and the CLB.

64-pin samples of the superset F280049C and evaluation modules (EVMs) are available. TI will announce 100-pin low-profile quad flat pack (LQFP) production shortly, followed by automotive-qualified versions of the 100-pin and 64-pin. The 56-pin production will follow late next year.
