The current development of motor control is becoming more and more diversified and complicated, and the site is also demanding more and more stringent performance requirements. Therefore, customers may consider developing their own dedicated control chip, and the programmability of FPGA can meet this demand.
For the different requirements of motor control, the inherent programmability and parallel processing characteristics of FPGA chips are very suitable for medium and high-end motor control applications. Because it performs parallel processing in pure hardware and does not occupy CPU resources, it can achieve high performance.
In the motor control market, many manufacturers focusing on FPGA technology have successively launched their own unique solutions. This series will introduce these manufacturers and their representative products in the field of motor control. First of all, Actel, one of the three giants of FPGAs.
Actel Fusion Series Devices
The Actel Fusion family of devices is the industry's first and only FPGA architecture with analog Flash architecture, combining FPGA digital cores, A/D converters, Flash memory, analog I/O, RTC and other digital and analog devices. The Fusion device has 2 to 8 Mbit internal users with Flash memory and 30 channels, up to 12-bit precision, up to 600 Ks/s sampling rate A/D converter, on-chip 100 MHz RC oscillator and PLL (lock Phase loops together work together to clock the FPGA to save on external clock overhead. These features greatly enhance the functionality of this family of FPGA devices, simplifying system design and dramatically reducing board area and total system cost. When the Fusion series FPGA device combines the software MCU cores such as 8051, CortexMl, and ARM7, the real SoC system can also be realized. The many features of the Actel Fusion family of devices make it widely used in the field of motor control. The Smartfusion digital-analog hybrid chip, which extends from it, is ideal for high-complexity motor control applications.
