Industry’s highest performing dual-core floating point MCUs for real time control
The C2000 Delfino 32bit F2837xD microcontrollers have dual-core C28x processing capabilities and dual real-time control accelerators, also known as control law accelerators (CLAs), from 800 MIPS of low latency floating-point performance. Designers can also reduce complexity by consolidating multiple embedded processors into a single MCU for applications requiring real-time signal analysis, such as high-end servo drives, solar central inverters, industrial uninterruptible power supplies (UPS) and more.
Customers can precisely control and monitor multiple feedback inputs simultaneously with the Delfino F2837xD MCU using powerful analog peripherals integrated on-chip. By providing four independent 16-bit analog-to digital converters (ADCs), the F2837xD MCU is able to precisely and efficiently manage multiple analog signals, which enables overall system throughput for solutions such as the monitoring of three-phase motors. Designers can also safely shut down their motors with the integrated windowed comparators, which provide critical power stage protection, while the sigma delta demodulators allow direct interface to isolated converters providing noise immunity for the MCU.
The Delfino F2837xD MCUs are the first devices in a series of innovative C2000 MCUs that will be pin- and software-compatible and provide varying performance ranges capable of addressing different performance requirements in a product line – from a servo drive for factory automation to an elevator drive. Future single-core derivatives allow customers to decrease hardware and software development time and cost.
The microcontrollers eliminate the need for multiple embedded processors with 800 MIPS combined performance from dual C28x cores and dual CLAs and offload main CPUs (C28x cores) from demanding control loop analysis with two real-time control accelerators, or control law accelerators (CLAs), creating additional bandwidth, allowing the main processor to focus on system diagnostics or applications management. The cores can swiftly execute trigonometric-based algorithms used in control functions, such as torque loops traditionally done in FPGAs with the new trigonometric math unit (TMU) accelerator included on the C28x cores and better predict motor failures by performing vibrational analysis with a viterbi complex unit (VCU II) accelerators.
Designers can fine-tune control and monitor multiple feedback loops using four 16-bit ADCs to improve system accuracy in industrial applications such as solar central inverters and high-end industrial UPS systems and reduce MCU input noise and enable isolated current shunt measurements with a seamless interface to the TI AMC1204 isolated delta sigma modulator.
The family is compatible with existing kits the F2837xD controlCARD uses the established C2000 controlCARD format making this hardware functional with existing application kits and centralized software development provides examples, header files and application libraries from the controlSUITE.
Fully featured Delfino F2837xD 32-bit microcontrollers are now sampling and start at approximately $18 USD in 1K unit orders. Developers can evaluate their new Delfino MCUs using the F2837xD docking station (TMDXDOCK28377D) for $219 USD and the modular controlCARD (TMDXCNCD28377D) for $159 USD.
