9 / 77 page EDE2508AEBG, EDE2516AEBG Data Sheet E1175E20 (Ver. 2.0) 9 ×8 ×16 Parameter Symbol Grade max. max. Unit Test condition Auto-refresh current IDD5 -8E -6E 90 85 90 85 mA tCK = tCK (IDD); Refresh command at every tRFC (IDD) interval; CKE is H, /CS is H between valid commands; Other control and address bus inputs are SWITCHING; Data bus inputs are SWITCHING Self-refresh current IDD6* 7 4 4 mA Self-Refresh Mode; CK and /CK at 0V; CKE ≤ 0.2V; Other control and address bus inputs are FLOATING; Data bus inputs are FLOATING Operating current (Bank interleaving) IDD7 -8E -6E 155 155 165 160 mA all bank interleaving reads, IOUT = 0mA; BL = 4, CL = CL(IDD), AL = tRCD (IDD) −1 × tCK (IDD); tCK = tCK (IDD), tRC = tRC (IDD), tRRD = tRRD(IDD), tRCD = 1 × tCK (IDD); CKE is H, /CS is H between valid commands; Address bus inputs are STABLE during DESELECTs; Data pattern is same as IDD4W Notes: 1. IDD specifications are tested after the device is properly initialized. 2. Input slew rate is specified by AC Input Test Condition. 3. IDD parameters are specified with ODT disabled. 4. Data bus consists of DQ, DM, DQS, /DQS, RDQS and /RDQS. IDD values must be met with all combinations of EMRS bits 10 and 11. 5. Definitions for IDD L is defined as VIN ≤ VIL (AC) (max.) H is defined as VIN ≥ VIH (AC) (min.) STABLE is defined as inputs stable at an H or L level FLOATING is defined as inputs at VREF = VDDQ/2 SWITCHING is defined as: inputs changing between H and L every other clock cycle (once per two clocks) for address and control signals, and inputs changing between H and L every other data transfer (once per clock) for DQ signals not including masks or strobes. 6. Refer to AC Timing for IDD Test Conditions. 7. When TC ≥ +85°C, IDD6 must be derated by 80%. IDD6 will increase by this amount, if TC ≥ +85°C and double refresh option is still enabled. AC Timing for IDD Test Conditions For purposes of IDD testing, the following parameters are to be utilized. DDR2-800 DDR2-667 Parameter 5-5-5 5-5-5 Unit CL (IDD) 5 5 tCK tRCD (IDD) 12.5 15 ns tRC (IDD) 57.5 60 ns tRRD (IDD) 7.5 7.5 ns tCK (IDD) 2.5 3 ns tRAS (min.)(IDD) 45 45 ns tRAS (max.)(IDD) 70000 70000 ns tRP (IDD) 12.5 15 ns tRFC (IDD) 75 75 ns |
