具有 400MIPS、1xCPU、1xCLA、FPU、TMU、512KB 闪存、CLB、EMIF、16 位 ADC 的 C2000™ 32 位 MCU 176-HLQFP -40 to 105

The Delfino TMS320F2837xS is a powerful 32-bit floating-point microcontroller unit MCU designed for advanced closed-loop control applications such as industrial drives and servo motor control; solar inverters and converters; digital power; transportation; and power line communications. Complete development packages for digital power and industrial drives are available as part of the powerSUITE and DesignDRIVE initiatives.

The real-time control subsystem is based on ’s 32-bit C28x floating-point CPU, which provides 200 MHz of signal processing performance. The C28x CPU is 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 F2837xS microcontroller family features a CLA real-time control co-processor. 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 TMS320F2837xS supports up to 1MB 512KW of onboard flash memory with error correction code ECC and up to 164KB 82KW of SRAM. Two 128-bit secure zones are also available on the CPU for code protection.

Performance analog and control peripherals are also integrated on the F2837xS 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 ISO11898-1/CAN 2.0B-compliant, and a new uPP interface extend the connectivity of the F2837xS. 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.
