Typical applications include industrial control nodes, motor drives, sensor hubs, and CAN-bus gateways where the combination of a 32-bit core, 50 MHz throughput, and multiple serial interfaces fits a mid-complexity embedded design.
This means TI has flagged it for eventual end-of-life; new production designs should avoid this part.
The 64-LQFP package with 33 I/O pins provides enough GPIO for sensor interfacing and control logic in a compact board area.
It is not recommended for new designs, but existing BOMs can still be supported through surplus and broker channels.
