Preliminary
GS8324Z18(B/C)/GS8324Z36(B/C)/GS8324Z72(C)
Note: These parameters are sample tested.
Notes:
1. Junction temperature is a function of SRAM power dissipation, package thermal resistance, mounting board temperature, ambient. Temper-
ature air flow, board density, and PCB thermal resistance.
2. SCMI G-38-87
3. Average thermal resistance between die and top surface, MIL SPEC-883, Method 1012.1
