C2000 ™ The 32-bit microcontroller is optimized for processing, induction and drive to improve closed-loop performance for real-time control applications such as industrial motor drives, photovoltaic inverters and digital power supplies, electric vehicles and transportation, motor control, and induction and signal processing. The C2000 series includes advanced performance MCU and entry-level performance MCU.
TMS320F2837xS is a powerful 32-bit floating point microcontroller unit (MCU) designed for advanced closed-loop control applications such as industrial motor drivers, photovoltaic inverters and digital power supplies, electric vehicles and transportation, as well as induction and signal processing. In order to accelerate application development, Digital Power Software Development Kit (SDK) for C2000 MCU and C2000 are provided ™ MotorControl software development kit for MCU
(SDK)。 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 has been further improved through the new TMU accelerator and VCU accelerator. The TMU accelerator can quickly perform the trigonometry algorithms commonly used in transformation and torque loop calculation; VCU accelerator can shorten the time of complex mathematical operations commonly seen in coding applications.
F2837xS microcontroller product series has CLA real-time control coprocessor. CLA is an independent 32-bit floating point processor, which runs at the same speed as the main CPU. This CLA responds to external 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 CLA to service time critical functions, the main C28x CPU is free to perform other tasks, such as communication and diagnostics.
TMS320F2837xS supports onboard flash memory up to 1MB (512KW) with error correction code (ECC) and SRAM up to 164KB (82KW). There are also two 128 bit security zones on the CPU for code protection.
F2837xS MCU also integrates high-performance simulation and control peripherals to further realize system integration. Four independent 16 bit ADC can accurately and efficiently manage multiple analog signals, thus ultimately improving the system throughput. new type Σ-Δ Filter Module (SDFM) and Σ-Δ Modulators can be used together to realize isolated parallel current measurement. The comparator subsystem with window comparator (CMPSS) allows protection of the power level when current limits are exceeded or not met. Other analog and control peripherals include DAC, PWM, eCAP, eQEP and other peripherals.
The EMIF, CAN module (conforming to ISO 11898-1/CAN 2.0B standard) and other peripherals as well as the new uPP interface expand the F2837xS connectivity.
The uPP interface is C2000 ™ The new function of MCU supports high-speed parallel connection with FPGA or other processors by using similar uPP interfaces. most
The USB 2.0 port with MAC and PHY allows users to easily add Universal Serial Bus (USB) connectivity to their applications.
