Key Differentiators
- Integrated VCU for Viterbi and complex math (vs TMS320F28069MPZT)
- Higher performance than TMS320F2806PZA (vs TMS320F2806PZA)
- Pin-compatible with higher-performance TMS320F28377SPTPQ (vs TMS320F28377SPTPQ)
Design Notes
The TMS320F28069PZT has an internal voltage regulator that allows single-rail operation from a 3.3V supply. However, for lower power dissipation, an external 1.8V supply can be connected to the VDD pins. Ensure proper decoupling with 100 nF capacitors placed close to each VDD and VDDIO pin, and a 10 uF bulk capacitor on the main supply rail.
For the 100-pin LQFP package, use a 4-layer PCB with dedicated power and ground planes. Place the crystal oscillator (10 MHz) and its load capacitors as close to the X1/X2 pins as possible, with a ground guard ring to minimize noise. Route high-speed signals like USB and CAN with controlled impedance and proper termination.
Do not exceed the absolute maximum ratings for VDDIO (3.6V) and VDD (2.1V). Ensure the boot mode pins are configured correctly to avoid unintended boot from flash. When using the internal oscillator, note that it requires a 10 MHz crystal; using a different frequency may require software configuration. Also, avoid floating unused GPIO pins by configuring them as outputs or enabling internal pull-ups.
Compliance Information
