28500-DSH-002-C
580-pin TBGA
GENERAL NOTE:
1. LFM-linear feet per minute.
2. LMS-linear meters per second.
3. Junction to case temperature (°C): Tjc =Tac + (θja x Pd).
Package
Tjc = θja x Pd (measured) + Tac (measured)
Where Tjc = Junction Temperature (see
θja = Thermal Resistance
Tac = Ambient Case Temperature (see
Pd = Power Dissipation = VDD_c x IDD (see
