F280049 Key Features and Benefits
1. Powerful real-time control performance
The F280049 features TI’s 32-bit C28x DSP core, operating at a clock speed of up to 100 MHz. Combined with an IEEE 754 single-precision floating-point unit (FPU) and a trigonometric unit (TMU), it significantly accelerates motor control and digital power algorithms such as Park/Clarke transformations and torque-loop calculations. The TMU can accelerate common trigonometric operations from 3x to 4x the clock cycle.
2. Dedicated Control Law Accelerator (CLA)
The CLA integrated into the chip is a 32-bit floating-point maths accelerator independent of the main CPU, also operating at a clock speed of 100 MHz, capable of executing code in parallel with the main CPU. This architecture allows critical control loops to be offloaded to the CLA, effectively offloading the CPU’s computational load and doubling the system’s control performance.
3. High-Precision Analogue and PWM Peripherals
Three 12-bit ADCs: support up to 21 external channels, feature synchronous sample-and-hold capability, and are ideally suited for three-phase current/voltage detection
16 high-resolution PWM (HRPWM) channels: precision down to the 150 ps level, supporting dead-time control, phase shifting and fault protection, suitable for complex power supply topologies
Integrated Programmable Gain Amplifiers (PGAs): The analogue front-end incorporates seven PGAs, supporting on-chip voltage-controlled amplification, thereby reducing the need for external components
4. Extensive Communication Interfaces
Supports a variety of communication protocols including CAN FD (up to 5 Mbps), SPI, I²C, SCI/UART, LIN and PMBus, facilitating efficient data exchange with external devices, sensors and host systems.
5. Comprehensive functional safety and reliability
Multiple safety mechanisms are built-in, including memory ECC/parity checking, windowed watchdog, clock loss detection and brown-out reset (BOR), supporting system development to the ISO 26262 ASIL-B functional safety level. The operating temperature range spans from –40°C to +125°C, making it suitable for wide-temperature environments such as industrial and automotive applications.
6. Wide Voltage Range and Low-Power Design
Featuring a 1.2 V core and 3.3 V I/O design, the device integrates an on-chip voltage regulator (VREG) or DC-DC converter to support single-supply operation, simplifying system power supply design.
