TI TMS320F28377DPTPT

Delfino TMS320F2837xD is a powerful 32-bit floating-point microcontroller unit (MCU) designed for advanced closed-loop control applications, such as industrial drives and servo motor control, solar inverters and converters, digital power supplies, power delivery, and power line communication. The F2837xD supports a new dual-core C28x architecture, significantly improving system performance; it also integrates analog and control peripherals, allowing designers to integrate control architectures and eliminating the need for multiple processors in high-end systems.

The dual real-time control subsystems are based on TI's 32-bit C28x floating-point CPU, providing 200MHz signal processing performance in each core. The performance of the C28x CPU is further enhanced by the new TMU accelerator and VCU accelerator. The TMU accelerator can quickly execute algorithms containing trigonometric operations common in transformation and torque loop calculations; the VCU accelerator can shorten the time of complex mathematical operations common in coding applications.

The F2837xD microcontroller series uses two CLA real-time control coprocessors. The CLA is an independent 32-bit floating-point processor that runs at the same speed as the main CPU. The CLA responds to peripheral triggers and executes code simultaneously with the main C28x CPU. This parallel processing function can effectively double the computing performance of the real-time control system. By using the CLA to perform time-critical functions, the main C28x CPU can be freed up for other tasks such as communication and diagnosis. The dual C28x+CLA architecture enables intelligent partitioning between various system tasks. For example, one C28x+CLA core can be used to track speed and position, while the other C28x+CLA core can be used to control torque and current loops.

The TMS320F2837xD supports up to 1MB (512KW) of on-board flash memory (with error correction code (ECC)) and up to 204KB (102KW) of SRAM. Two 128-bit security zones are also provided on each CPU for code protection.

The F2837xD MCU also integrates performance analog and control peripherals to further achieve system integration. Four independent 16-bit ADCs can accurately and efficiently manage multiple analog signals, ultimately improving system throughput. The new Σ-Δ filter module (SDFM) works with the Σ-Δ modulator to achieve isolated shunt measurement. The comparator subsystem (CMPSS) containing window comparators can protect the power stage when current limit conditions are exceeded or not met. Other analog and control peripherals include DAC, PWM, eCAPs, eQEP, and other peripherals.

With the configurable logic module (CLB), Texas Instruments (TI) can provide additional interface and control functions for selected C2000 devices.

Peripherals such as EMIF, CAN modules (compliant with ISO11898-1/CAN 2.0B), and the new uPP interface extend the connectivity of the F2837xD. The uPP interface is a new feature of the C2000 MCU, supporting high-speed parallel connection with FPGA or other processors using a similar uPP interface. Finally, the USB 2.0 port with MAC and PHY allows users to easily add universal serial bus (USB) connectivity to their applications.
