Low power DDR 1Gbit x16 dual die implementation
Each die organized as 4 banks x 8 MBit x 16
2 KByte page size
Two Chip Selects (2 CS) for reducing power consumption
Options for one CKE and two CKEs are available. Option with second CKE provides futher power saving
Double-data-rate architecture: two data transfers per clock cycle
Bidirectional data strobe (DQS) is transmitted / received with data; to be used in capturing data at the receiver
DQS is edge-aligned with data for READs and center-aligned with data for WRITEs
Differential clock input (CK / CK)
Commands entered on positive CK edge; data and mask data are referenced to both edges of DQS
Four internal banks for concurrent operation
Programmable CAS latency: 2 and 3
Programmable burst length: 2, 4, 8 and 16
Programmable drive strength (full, half, quarter)
Auto refresh and self refresh modes
8192 refresh cycles / 64ms
Auto precharge
Commercial (-0°C to +70°C) and Extended (-25°C to +85°C) operating temperature ranges
60-ball PG-VFBGA-60-6 package (11 × 10.5 × 1.0 mm)
RoHS Compliant Product1)

Low supply voltages: VDD = 1.70 V − 1.90 V, VDDQ = 1.70 V − 1.90 V
Optimized operating (IDD0, IDD4), self refresh (IDD6) and standby currents (IDD2, IDD3
DDR I/O scheme with no DLL
Programmable Partial Array Self Refresh (PASR)
Temperature Compensated Self-Refresh (TCSR), controlled by on-chip temperature sensor
