The QXS320F280049RevB is a 32-bit processor benchmarked against TI's TMS320F28004x family. The QXS320F280049RevB is a 32-bit processor benchmarked against TI's TMS320F28004x series. It is mainly targeted at real-time control applications (such as industrial motor drives, photovoltaic inverters and digital power supplies, motor control of electric vehicles, and air conditioning inverter).

The QXS320F280049RevB has a self-developed 32-bit CPU core benchmarked against the TI C28x, which provides 160MHz of processing power.

QXS320F280049RevB internal also integrated FPU, TMU and VCU extended instruction set, FPU can provide 32-bit floating-point acceleration instructions, TMU can quickly execute algorithms that contain transformations and torque loop calculations of common trigonometric operations, VCU extended instruction set to reduce the latency of coding applications common complex mathematical operations.

The QXS320F280049RevB utilizes a dual-core architecture, where CPU0 and CPU1 can run independently in parallel or communicate with each other. Each core has its own independent storage resources, and both have independent access to the major peripherals required in a typical control system. The two cores can communicate with each other through interrupts, special registers and shared memory.

The QXS320F280049RevB also integrates high-performance analog peripherals and enhanced control peripherals. Three independent 12-bit conventional ADCs with a sampling rate of 3MSPS manage multiple analog signals accurately and efficiently, ultimately increasing system throughput. Seven PGAs on the analog front-end enable on-chip voltage regulation prior to conversion. Seven analog comparator modules allow continuous monitoring of input voltage levels for trip conditions. Advanced control peripherals (with frequency-independent ePWM/HRPWM and eCAP) provide excellent control of the system. Built-in 4-channel SDFM allows seamless integration of oversampling Σ-Δ modulators on the isolation layer. Connectivity is supported through a variety of industry-common communication ports (e.g., SPI, SCI, I2C, LIN, and CAN2.0, CAN FD), and multiple multiplexing options are provided for excellent signal placement in a variety of applications. the QXS320F280049RevB supports both PMBus and FSI. the Embedded Real-Time Analyzer and Diagnostics (ERAD) Module supports the QXS320F280049RevB by The Embedded Real-Time Analysis and Diagnostics (ERAD) module enhances device debugging and system analysis by providing additional hardware breakpoints and counters for analysis.

The QXS320F280049RevB supports up to 512KB of configurable instruction RAM or data RAM as well as an additional 512KB of instruction RAM and 1MB of Flash memory to accommodate most embedded scenarios.The QXS320F280049RevB also supports 8KB of bootloader instruction RAM for flexible configuration of the boot process.
