Key features include the 120 MHz C28x core with a floating-point unit, 128 KB flash, HRPWM for high-resolution pulse generation, CAN-FD for robust communication, and lockstep ASIL B safety. The 48-pin HTQFP package provides a compact solution while maintaining thermal performance. The device also supports multiple serial interfaces, including UART, SPI, I2C, and CAN-FD, enabling flexible system integration.
The C28x core is a Harvard-architecture processor with a unified memory map. Its floating-point unit accelerates complex control algorithms. The HRPWM module supports high-resolution duty cycles up to 150 ps, enabling precise control in power converters. CAN-FD supports higher data rates and larger payloads for automotive networks. The lockstep ASIL B feature enhances system safety by detecting faults in the CPU, making it suitable for ISO 26262 applications.
Typical applications include traction motor control in electric vehicles, on-board chargers, power factor correction, industrial servo drives, battery management systems, and solar inverters. The combination of HRPWM and CAN-FD makes it suitable for real-time control with communication. Its wide operating temperature range ensures reliability in harsh automotive environments.
When designing, decouple the supply pins with ceramic capacitors and use a dedicated ground plane. The HRPWM outputs should be routed away from sensitive analog signals to minimize noise coupling. It is also important to provide proper thermal management through the exposed pad and vias, especially at high ambient temperatures.

Key Differentiators
- Only 128KB flash in the 48-HTQFP package (vs TMS320F2800154-Q1)
- Automotive safety with lockstep ASIL B (vs TMS320F2800155 (non-Q1))
- Balanced memory and peripherals (vs TMS320F2800157-Q1)
Design Notes
Decouple each supply pin (VDD, VDDA) with a 100 nF ceramic capacitor placed as close to the pin as possible, and add a 10 uF ceramic capacitor at the board level. The C2000 MCU requires clean power rails to ensure ADC accuracy and avoid spurious resets.
The 48-pin HTQFP package has an exposed thermal pad. Ensure the pad is soldered to a solder pad with thermal vias to the ground plane. For operation at high ambient temperatures, add airflow or a heatsink to keep the junction temperature below 125C. The MCU's CPU power consumption at 120 MHz may exceed 100 mW, so thermal verification is recommended.
Route HRPWM output signals away from the ADC input traces to prevent noise coupling. Use short, symmetric traces for PWM pairs to maintain matched timing. Place the crystal or oscillator close to the XTAL pins and keep the load capacitors grounded directly.
