Texas Instruments TMS320F28002x/TMS320F28002x-Q1 C2000 32-Bit MCUs

Texas Instruments TMS320F28002x/TMS320F28002x-Q1 C2000 32-Bit Microcontrollers (MCUs) is a member of the C2000™ real-time microcontroller family of scalable, ultra-low latency devices. These devices are designed for efficiency in power electronics, including but not limited to high power density, high switching frequencies, and supporting the use of GaN and SiC technologies. The real-time control subsystem is based on the Texas Instruments 32-bit C28x DSP core, which provides 100MHz of signal-processing performance for floating- or fixed-point code running from either on-chip flash or SRAM. The C28x CPU is boosted by the Trigonometric Math Unit (TMU) and VCRC (Cyclical Redundancy Check) extended instruction sets, speeding up common algorithms key to real-time control systems.

High-performance analog blocks are integrated into the F28002x real-time microcontroller (MCU) and are closely coupled with the processing and PWM units to provide optimal real-time signal chain performance. Fourteen PWM channels, all supporting frequency-independent resolution modes, enable control of various power stages from a 3-phase inverter to advanced multi-level power topologies. The inclusion of the Configurable Logic Block (CLB) allows the user to add custom logic and potentially integrate FPGA-like functions into the C2000 real-time MCU.

Interfacing is supported through various industry-standard communication ports (such as SPI, SCI, I²C, PMBus, LIN, and CAN) and offers multiple pin-muxing options for optimal signal placement. The Fast Serial Interface (FSI) enables up to 200 Mbps of robust communications across an isolation boundary. New to the C2000 platform is the Host Interface Controller (HIC), a high-throughput interface that allows an external host to access the resources of the TMS320F28002x/TMS320F28002x-Q1 directly. The TMS320F28002x-Q1 devices are AEC-Q100 qualified for automotive applications.
