TMS320F28003x supports C28x and CLA as processing elements that boosts system performance for closed loop control applications. This is a powerful 32-bit floating-point microcontroller unit (MCU) that lets system integrator to access crucial control peripherals, differentiated analog, and nonvolatile memory on a single device.
The C28x CPU is further boosted by the Floating-Point Unit (FPU), Trigonometric Math Unit (TMU), Nonlinear Proportional Integral Derivative (NLPID) control, Fast Integer Division (FINTDIV) and Cyclic Redundancy Check (VCRC) accelerators. FPU supports IEEE754 floating point operations. TMU enables fast execution of algorithms with trigonometric operations common in transforms and torque loop calculations. NLPID enables fast execution of Nonlinear PID controls. The VCRC engine reduces the time for complex math operations common in encoded applications. Users may refer to Enhancing the Computational Performance of the C2000™ Microcontroller Family to see how the accelerators can be employed to increase the performance of the MCU in many real-time applications.
The CLA is an independent 32-bit floating-point accelerator that runs at the same frequency as the main C28x CPU, responding to peripheral triggers with minimum event latency and executing code concurrently with the main CPU.
The TMS320F28003x supports up to 384KB (192KW) of on-chip flash memory with error correction code (ECC) and up to 69KB (34.5KW) of SRAM with parity or ECC.
High performance analog and control peripherals are also integrated to further enable system consolidation. Three independent 12-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 the Digital-to-Analog Converter (DAC), Enhanced Pulse Width Modulation (ePWM), Enhanced Capture (eCAP), and Enhanced Quadrature Encoder Pulse (eQEP).
Peripherals such as Controller Area Network (CAN) modules (ISO11898-1/CAN 2.0B-compliant), Inter-Integrated Communication (I2C) Bus, Local Interconnect Network (LIN), Serial Communications Interface (SCI), Serial Peripheral Interface (SPI), Power Management Bus (PMBus) Interface, and Fast Serial Interface (FSI) extend connectivity of TMS320F28003x MCU. The Fast Serial Interface (FSI) module is a serial communication peripheral capable of reliable high-speed communication across isolation devices.
