8 / 151 page EDJ1104BBSE, EDJ1108BBSE, EDJ1116BBSE Data Sheet E1375E50 (Ver. 5.0) 8 Recommended DC Operating Conditions (TC = 0 °C to +85°C, VDD, VDDQ = 1.5V ± 0.075V) Parameter Symbol min. typ. max. Unit Notes Supply voltage VDD 1.425 1.5 1.575 V 1, 2 Supply voltage for DQ VDDQ 1.425 1.5 1.575 V 1, 2 Input reference voltage VREFCA (DC) 0.49 × VDD 0.50 × VDD 0.51 × VDD V 3, 4 Input reference voltage for DQ VREFDQ (DC) 0.49 × VDDQ 0.50 × VDDQ 0.51 × VDDQ V 3, 4 Notes: 1. Under all conditions VDDQ must be less than or equal to VDD. 2. VDDQ tracks with VDD. AC parameters are measured with VDD and VDDQ tied together. 3. The AC peak noise on VREF may not allow VREF to deviate from VREF(DC) by more than ±1% VDD (for reference: approx ±15 mV). 4. For reference: approx. VDD/2 ± 15 mV. AC and DC Input Measurement Levels (TC = 0 °C to +85°C, VDD, VDDQ = 1.5V ± 0.075V) Single-Ended AC and DC Input Levels for Command and Address Parameter Symbol min. typ. max. Unit Notes DC input logic high VIHCA (DC) VREF + 0.100 VDD V 1 DC input logic low VILCA (DC) VSS VREF − 0.100 V 1 AC input logic high VIHCA (AC) VREF + 0.175 * 2 V 1 AC input logic low VILCA (AC) * 2 VREF − 0.175 V 1 AC input logic high VIHCA (AC150) VREF + 0.150 * 2 V 1 AC input logic low VILCA (AC150) * 2 VREF − 0.150 V 1 Notes: 1. For input only pins except /RESET; VREF = VREFCA. 2. See Overshoot and Undershoot Specifications section. Single-Ended AC and DC Input Levels for DQ and DM Parameter Symbol min. typ. max. Unit Notes DC input logic high VIHDQ (DC) VREF + 0.100 VDD V 1 DC input logic low VILDQ (DC) VSS VREF − 0.100 V 1 AC input logic high DDR3-800, 1066 VIHDQ (AC) VREF + 0.175 * 2 V 1 DDR3-1333, 1600 VIHDQ (AC) VREF + 0.150 * 2 V 1 AC input logic low DDR3-800, 1066 VILDQ (AC) * 2 VREF − 0.175 V 1 DDR3-1333, 1600 VILDQ (AC) * 2 VREF − 0.150 V 1 Notes: 1. For DQ and DM: VREF = VREFDQ. 2. See Overshoot and Undershoot Specifications section. |
