FAQ
What is the maximum operating frequency of the TMS320F28064UPNT?
The TMS320F28064UPNT operates at a maximum CPU frequency of 90 MHz, corresponding to an 11.11-ns instruction cycle time. This speed is achieved using an internal PLL with either the on-chip zero-pin oscillators or an external crystal/clock source connected to X1/X2 pins. The device maintains full peripheral functionality-including ADC sampling and ePWM updates-at this rated frequency under recommended operating conditions (3.3 V, –40°C to 105°C).
Does the TMS320F28064UPNT support USB functionality?
Yes, the TMS320F28064UPNT supports full-speed USB 2.0 with both device and host mode capability. As a member of the "U" variant series (denoted by "U" in the part number), it includes the USB PHY and controller required for direct connection to USB hosts or peripherals without external transceivers. This feature is confirmed in the Device Comparison table and functional block diagram of the official SPRS698J datasheet.
How many high-resolution PWM channels does the TMS320F28064UPNT have?
The TMS320F28064UPNT provides 7 high-resolution PWM (HRPWM) channels, derived from its 14 total ePWM outputs. Each HRPWM channel supports sub-nanosecond duty-cycle resolution and dual-edge control, enabling precise gate-drive timing for wide-bandgap power devices. This count is explicitly listed in the Device Comparison table under "High-resolution ePWM Channels" for the 28064U variant.
What package type and thermal features does the TMS320F28064UPNT use?
The TMS320F28064UPNT is offered exclusively in the 100-pin PowerPAD™ HTQFP (PZP) package - a thermally enhanced thin quad flatpack measuring 14.0 mm × 14.0 mm. Its exposed PowerPAD must be soldered to the PCB ground plane using thermal vias to dissipate heat effectively; the pad is not electrically connected to internal VSS but serves solely as a thermal conduction path per TI's PowerPAD design guidelines.
Is the TMS320F28064UPNT pin-compatible with other F2806x devices?
No, the TMS320F28064UPNT is not fully pin-compatible with other F2806x variants such as the TMS320F28069PZP. While both use the same 100-pin PZP package footprint, differences in peripheral enablement - including USB signal assignment, HRCAP/eQEP pin mapping, and analog input routing - result in non-interchangeable pin functions. Board layout must be verified against the specific TMS320F28064UPNT pin diagram in Section 6.2 of SPRS698J.
