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 TMS320F2838x is a powerful 32-bit floating-point microcontroller unit (MCU) designed for advanced closed-loop control applications. The F2838x supports a dual-core C28x architecture along with a new Connectivity Manager that offloads critical communication tasks, significantly boosting system performance. The integrated analog and control peripherals with advanced connectivity peripherals like EtherCAT and Ethernet also let designers consolidate real-time control and real-time communications architectures, reducing requirements for multicontroller 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 TMU accelerator, which enables fast execution of algorithms with trigonometric operations common in transforms and torque loop calculations.

The F2838x 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 Connectivity Manager subsystem is based on the Cortex-M4 CPU and has access to advanced communication IPs like EtherCAT, Ethernet, MCAN (CAN-FD), and AES.

The TMS320F2838x supports up to 1.5MB (512KB per CPU) of flash memory with error correction code (ECC) and up to 312KB (216KB total for C28x CPU1 and CPU2, and 96KB on the Cortex-M4) of SRAM. Two 128-bit secure zones are also available on the device for code protection.

Performance analog and control peripherals are also integrated on the F2838x 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 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), EtherCAT, Ethernet, and MCAN (CAN-FD) extend the connectivity of the F2838x. Lastly, a USB 2.0 port with MAC and PHY lets users easily add universal serial bus (USB) connectivity to their application.

The Embedded Real-Time Analysis and Diagnostic (ERAD) module enhances the debug and system analysis capabilities of the device by providing additional hardware breakpoints and counters for profiling.
