2 / 129 page

KEY FEATURE

•Double-data rate architecture; two data transfers per clock cycle

• Bidirectional data strobes (DQS, DQS#), These are transmitted/received with data to be used in capturing data at the

receiver

• Differential clock inputs (CK and CK#)

• Differential data strobes (DQS and DQS#)

• Commands & addresses entered on both positive and negative CK edges; data and data mask referenced to both

edges of DQS

• 8 internal banks for concurrent operation

• Data mask (DM) for write data

• Burst Length: 4 (default), 8 or 16

• Burst Type: Sequential or Interleave

• Read & Write latency : Refer to Table 51 LPDDR2 AC Timing Table

• Auto Precharge option for each burst access

• Configurable Drive Strength

• Auto Refresh and Self Refresh Modes

• Partial Array Self Refresh and Temperature Compensated Self Refresh

• Deep Power Down Mode

• HSUL_12 compatible inputs

• VDD1/VDD2/VDDQ/VDDCA

: 1.8V/1.2V/1.2V/1.2V

• No DLL : CK to DQS is not synchronized

• Edge aligned data output, center aligned data input

• Operating Temperature : -

30 to 85 °C

• Auto refresh duty cycle : 3.9us

• Package type : 134-ball FBGA 10x11.5x1.0mm (max)
