Key Differentiators
- Higher flash memory capacity (vs TMS320F2800156-Q1)
- Grade 0 temperature support (vs TMS320F2800155-Q1)
- Can-FD with functional safety (vs TMS320F2800154-Q1)
Design Notes
Connect a 0.1 uF ceramic capacitor and 10 uF tantalum capacitor on each VDDIO pin. Use a 1.2 V regulator for the VDD core with 0.1 uF bypass. Separate analog and digital grounds, joining them at a single point near the MCU. This reduces noise effects on ADC measurements.
Place the crystal oscillator within 20 mm of XTAL pins with short traces. Route CAN-FD differential pairs with 120-ohm impedance and length matching. Keep high-frequency PWM traces away from analog input signals to prevent coupling into ADC channels.
Ensure XRS reset pin has a 10 kOhm pull-up to VDDIO and a 1 uF capacitor to ground for reliable power-on reset. For CAN-FD communication, use the ISO6442-Q1 isolator to protect the transceiver. Avoid floating unused input pins - connect them to appropriate logic levels.
Compliance Information
AEC-Q100 Grade 0 and Grade 1 qualified per TI product page. RoHS compliant.
