This frequency is fully supported across the –40°C to 125°C ambient temperature range with appropriate voltage and thermal management per TI's recommended operating conditions.

Does the TMS320F2800137RHBR support CAN communication?

Yes, the TMS320F2800137RHBR includes one Controller Area Network (CAN/DCAN) bus port compliant with ISO 11898-1. It supports standard (11-bit) identifier frames, bit rates up to 1 Mbps, and integrated message RAM with transmit/receive FIFOs - enabling robust communication in motor drive and industrial automation networks.

What analog-to-digital converter (ADC) capabilities does the TMS320F2800137RHBR provide?

The TMS320F2800137RHBR integrates two independent 12-bit ADCs, each capable of 4 million samples per second (4 MSPS). Each ADC includes four post-processing blocks (PPBs) for hardware-based filtering, offset correction, and windowed comparison - reducing CPU load during high-speed current/voltage acquisition in real-time control loops.

Is the TMS320F2800137RHBR pin-compatible with other members of the F280013x family?

Yes, the TMS320F2800137RHBR shares identical pinout, package dimensions, and electrical characteristics with TMS320F2800135RHBR and TMS320F2800133RHBR in the 32-pin RHB VQFN variant. All three devices support the same peripheral mapping and GPIO functionality - enabling drop-in replacement based on flash size requirements.
