9 Detailed Description

9.1 Overview

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. Complete development packages for digital

power and industrial drives are available as part of the powerSUITE and DesignDRIVE initiatives. 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

200 MHz 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.
