512Mb: x16, x32 Mobile LPDDR SDRAM
Features
Mobile Low-Power DDR SDRAM
MT46H32M16LF – 8 Meg x 16 x 4 banks
MT46H16M32LF – 4 Meg x 32 x 4 banks
MT46H16M32LG – 4 Meg x 32 x 4 banks
Features
• V_DD/V_DDQ = 1.70–1.95V
• Bidirectional data strobe per byte of data (DQS)
• Internal, pipelined double data rate (DDR)
architecture; two data accesses per clock cycle
• Differential clock inputs (CK and CK#)
• Commands entered on each positive CK edge
• DQS edge-aligned with data for READs; center-
aligned with data for WRITEs
• 4 internal banks for concurrent operation
• Data masks (DM) for masking write data; one mask
per byte
• Programmable burst lengths (BL): 2, 4, 8, or 16
• Concurrent auto precharge option is supported
• Auto refresh and self refresh modes
• 1.8V LVCMOS-compatible inputs
• Temperature-compensated self refresh (TCSR)
• Partial-array self refresh (PASR)
• Deep power-down (DPD)
• Status read register (SRR)
• Selectable output drive strength (DS)
• Clock stop capability
• 64ms refresh, 32ms for automotive temperature
