1G bits DDR Mobile RAM
WTR (Wide Temperature Range)
EDD10321BBH-TS (32M words × 32 bits)
Specifications
• Density: 1G bits
• Organization: 8M words × 32 bits × 4 banks
• Package: 90-ball FBGA
Lead-free (RoHS compliant) and Halogen-free
• Power supply: VDD, VDDQ = 1.7V to 1.95V
• Data rate: 400Mbps/333Mbps (max.)
• 4KB page size
Row address: A0 to A12
Column address: A0 to A9
• Four internal banks for concurrent operation
• Interface: LVCMOS
• Burst lengths (BL): 2, 4, 8
• Burst type (BT):
Sequential (2, 4, 8)
Interleave (2, 4, 8)
• /CAS Latency (CL): 3
• Precharge: auto precharge option for each burst
access
• Driver strength: normal, 1/2, 1/4
• Refresh: auto-refresh, self-refresh
• Refresh cycles: 8192 cycles/64ms
Average refresh period: 7.8µs
• Operating ambient temperature range
TA = −25°C to +85°C
Features
• DLL is not implemented
• Low power consumption
• Double-data-rate architecture; two data transfers per
one clock cycle
• The high-speed data transfer is realized by the 2 bits
prefetch pipelined architecture
• Bi-directional data strobe (DQS) is transmitted
/received with data for capturing data at the receiver.
• Data inputs, outputs, and DM are synchronized with
DQS
• DQS is edge-aligned with data for READs; center-
aligned with data for WRITEs
• Differential clock inputs (CK and /CK)
• Commands entered on each positive CK edge: data
and data mask referenced to both edges of DQS
• Data mask (DM) for write data
• Burst termination by burst stop command and
Precharge command
• Wide temperature range
TA = −25°C to +85°C
• Low Power Function below is not supported
Partal Array Self-Refresh (PASR)
Auto Temperature Compensated Self-Refresh
Deep power-down mode

Electrical Specifications
• All voltages are referenced to VSS (GND).
• After power up, wait more than 200 µs and then, execute power on sequence and CBR (Auto) refresh before
proper device operation is achieved.

Caution
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.

Notes: 1. VDDQ must be equal to VDD.
2. VIH (max.) = 2.3V (pulse width ≤ 5ns).
3. VIL (min.) = –0.5V (pulse width ≤ 5ns).
4. All voltage referred to VSS and VSSQ must be same potential.
5. VID (DC) and VID (AC) are the magnitude of the difference between the input level on CK and the input
level on /CK.
6. The value of VIX is expected to be 0.5 × VDDQ and must track variations in the DC level of the same.
