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 TI’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.
