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.
Compliance Information
Compliance data not present in verified web data. AEC-Q100 assumed based on 'Q1' suffix and automotive C2000 designation.
