Package Details, Pin Configuration, and Thermal Considerations for TMS320F28062PZTR

Supplied in a 100-pin LQFP (14x14 mm, 0.5 mm pitch), the TMS320F28062PZTR features a PowerPAD™ thermally enhanced lead frame (exposed pad), which must be connected to PCB ground for best thermal conduction. Key considerations for layout:

The exposed pad is not electrically tied to the die ground, but serves as a thermal path

For effective heat dissipation, a thermal land beneath the device with an array of vias is recommended

Package dimensions and solder mask registration should follow IPC guidelines and TI recommendations

Land pattern, stencil, and thermal pad details are critical for manufacturing reliability in high-power applications
