C2000™ 32-bit MCU with 800 MIPS, 2xCPU, 2xCLA, FPU, TMU, 1024 KB flash, EMIF, 12b ADC

C2000™ 32-bit

microcontrollers are optimized for processing, sensing, and actuation to

improve closed-loop performance in real-time control

applications such as industrial motor drives; solar inverters and digital power; electrical vehicles and transportation; motor control; and sensing and signal processing. The C2000 line includes

the Premium performance MCUs and the Entry performance MCUs.

The TMS320F2837xD is a powerful 32-bit

floating-point microcontroller unit (MCU) designed for advanced closed-loop control

applications such as industrial motor drives; solar inverters and digital power; electrical vehicles and transportation; and sensing and signal processing. To accelerate application

development, the DigitalPower software development kit (SDK) for C2000 MCUs

and the MotorControl software development kit (SDK) for C2000™

MCUs

are available.

The F2837xD supports a new dual-core C28x architecture that significantly boosts

system performance. The integrated analog and control peripherals also let designers

consolidate control architectures and eliminate multiprocessor use in high-end

systems.

The dual real-time control subsystems

are based on TI’s 32-bit C28x floating-point CPUs, which provide 200MHz of signal

processing performance in each core. The C28x CPUs are further boosted by the new

TMU accelerator, which enables fast execution of algorithms with trigonometric

operations common in transforms and torque loop calculations; and the VCU

accelerator, which reduces the time for complex math operations common in encoded

applications.

The F2837xD microcontroller family

features 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 concurrently with the main C28x

CPU. This parallel processing capability can effectively double the computational

performance of a real-time control system. By using the CLA to service time-critical

functions, the main C28x CPU is free to perform other tasks, such as communications

and diagnostics. 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 onboard flash memory with error correction code (ECC) and up to 204KB

(102KW) of SRAM. Two 128-bit secure zones are also available on each CPU for code

protection.

Performance analog and control

peripherals are also integrated on the F2837xD MCU to further enable system

consolidation. Four independent 16-bit ADCs provide precise and efficient management

of multiple analog signals, which ultimately boosts system throughput. The new

sigma-delta filter module (SDFM) works in conjunction with the sigma-delta modulator

to enable isolated current shunt measurements. The Comparator Subsystem (CMPSS) with

windowed comparators allows for protection of power stages 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 EMIFs, CAN modules

(ISO 11898-1/CAN 2.0B-compliant), and a new uPP interface extend the connectivity of

the F2837xD. The uPP interface is a new feature of the C2000™ MCUs and supports

high-speed parallel connection to FPGAs or other processors with similar uPP

interfaces. Lastly, a USB 2.0 port with MAC and PHY lets users easily add universal

serial bus (USB) connectivity to their application.
