Features

  • High-performance 240 MHz Arm® Cortex®-M7 core combined with a high level of analog and digital integration targeted at real-time control applications
  • Up to 1 MB Flash and 256 KB RAM, 16 KB instruction cache and 8 KB data cache. 256 KB of RAM includes 64 KB of ITCM RAM ensuring maximum CPU performance of fast control loops with minimal latency
  • 64-bit AXI memory interface with I-Cache and D-Cache – efficient access to external resources; interface to large external memories for a complete RTOS experience; support for richer HMI with higher resolution graphics, multiple connectivity stacks and middleware
  • 4 x 8ch 12-bit ADC’s sampling at 5 MSPS with a dual sample and hold circuitry, can capture current and voltage simultaneously for two motors giving true independent dual motor control
  • Ethernet option with True Random Number Generator and Cryptographic unit providing a low cost integrated connectivity solution
  • 2 eFlexPWM blocks provide 4 independent time bases per module with a highly flexible configuration that easily supports motor and power control topologies
  • Multiple instantiations of timer blocks provide a vast array of timers (44 channels) simplifying the complex task of advanced motor control
  • A single eFlexPWM block featuring 12 channels with Nano-Edge capability, providing up to 260pSec resolution on pulse width and frequency modulation
  • Up to 3 FlexCAN modules—High speed, high-reliability industrial communication
  • Inter-peripheral cross-bar, with And or Invert Logic, provides a highly flexible connection fabric between peripherals that supports simplified control topology implementation
