11 / 27 page Thermal Impedance Package Test PCB Substrate θ JA (C°/W) Airflow = 0 m/s θ JA (C°/W) Airflow = 1 m/s θ JA (C°/W) Airflow = 2 m/s θ JB (C°/W) θ JC (C°/W) 165 BGA 4-layer 19.1 15.9 14.9 7.2 2.3 Notes: 1. Thermal Impedance data is based on a number of of samples from mulitple lots and should be viewed as a typical number. 2. Please refer to JEDEC standard JESD51-6. 3. The characteristics of the test fixture PCB influence reported thermal characteristics of the device. Be advised that a good thermal path to the PCB can result in cooling or heating of the RAM depending on PCB temperature.

Rev: 1.03a 11/2011 11/27 © 2008, GSI Technology HSTL I/O DC Input Characteristics Parameter Symbol Min Max Units Notes DC Input Logic High VIH (dc) VREF + 0.1 VDD + 0.3 V 1, 4 DC Input Logic Low VIL (dc) –0.3 VREF – 0.1 V 1, 3 Notes: 1. Compatible with both 1.8 V and 1.5 V I/O drivers 2. These are DC test criteria. DC design criteria is VREF ± 50 mV. The AC VIH/VIL levels are defined separately for measuring timing param- eters. 3. VIL (Min)DC = –0.3 V, VIL(Min)AC = –1.5 V (pulse width ≤ 3 ns). 4. VIH (Max)DC = VDDQ + 0.3 V, VIH(Max)AC = VDDQ + 0.85 V (pulse width ≤ 3 ns). HSTL I/O AC Input Characteristics Parameter Symbol Min Max Units Notes AC Input Logic High VIH (ac) VREF + 200 — mV 2, 3 AC Input Logic Low VIL (ac) — VREF – 200 mV 2, 3 VREF Peak to Peak AC Voltage VREF (ac) — 5% VREF (DC) mV 1 Notes: 1. The peak to peak AC component superimposed on VREF may not exceed 5% of the DC component of VREF. 2. To guarantee AC characteristics, VIH,VIL, Trise, and Tfall of inputs and clocks must be within 10% of each other. 3. For devices supplied with HSTL I/O input buffers. Compatible with both 1.8 V and 1.5 V I/O drivers. |
