TI TMS320F28377SZWTT

C2000 32-bit microcontrollers are optimized for processing, sensing, and driving to improve the closed-loop performance of real-time control applications such as industrial motor drives, photovoltaic inverters and digital power supplies, electric vehicles and transportation, motor control, and sensing and signal processing. The C2000 series includes high-performance MCUs and entry-level performance MCUs.

TMS320F2837xS is a powerful 32-bit floating-point microcontroller unit (MCU) designed for advanced closed-loop control applications such as industrial motor drives, photovoltaic inverters and digital power supplies, electric vehicles and transportation, and sensing and signal processing. To accelerate application development, a DigitalPower software development kit (SDK) for C2000 MCUs and a MotorControl software development kit (SDK) for C2000 MCUs are provided.

The real-time control subsystem is based on TI's 32-bit C28X floating-point CPU, providing 200MHz signal processing performance. The performance of the C28x CPU is further enhanced by the new TMU accelerator and VCU accelerator. The TMU accelerator can quickly execute algorithms for trigonometric operations common in transformation and torque loop calculations; the VCU accelerator can shorten the time for complex mathematical operations common in coding applications.

The F2837xS microcontroller product family features a CLA real-time control coprocessor. 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 capability can effectively double the computational performance of real-time control systems. By using the CLA to serve time-critical functions, the main C28x CPU can freely perform other tasks such as communication and diagnosis.

TMS320F2837xS supports up to 1MB (512KW) of on-board flash memory with error correction code (ECC) and up to 164KB (82KW) of SRAM. There are also two 128-bit security zones on the CPU for code protection.

High-performance analog and control peripherals are also integrated on the F2837xS MCU to further enable 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 enable isolated current shunt measurements. A comparator subsystem (CMPSS) with window comparators allows protection of the power stage when current limit conditions are exceeded or not met. Other analog and control peripherals include DACs, PWMs, eCAPs, eQEPs, and other peripherals.

Peripherals such as EMIF, CAN modules (compliant with ISO 11898-1/CAN 2.0B standards), and the new uPP interface extend the connectivity of F2837xS. The uPP interface is a new feature of C2000 MCUs, supporting high-speed parallel connections with FPGAs or other processors using similar uPP interfaces. Finally, a USB 2.0 port with MAC and PHY allows users to easily add Universal Serial Bus (USB) connectivity to their applications.
