N16D1633LPA
Advance Information
512K × 16 Bits × 2 Banks Low Power Synchronous DRAM
DESCRIPTION
These N16D1633LPA are low power 16,777,216 bits CMOS Synchronous DRAM organized as 2 banks of 524,288
words x 16 bits. These products are offering fully synchronous operation and are referenced to a positive edge of the
clock. All inputs and outputs are synchronized with the rising edge of the clock input. The data paths are internally
pipelined to achieve very high bandwidth. All input and output voltage levels are compatible with LVTTL.
Features
• JEDEC standard 3.0V/3.3V power supply.
• Auto refresh and self refresh.
• All pins are compatible with LVTTL interface.
• 4K refresh cycle / 64ms.
• Programmable Burst Length and Burst Type.
- 1, 2, 4, 8 or Full Page for Sequential Burst.
- 4 or 8 for Interleave Burst.
• Programmable CAS Latency : 2,3 clocks.
• Programmable Driver Strength Control.
- Full Strength or 1/2, 1/4 of Full Strength
• Deep Power Down Mode
• All inputs and outputs referenced to the positive
edge of the system clock.
• Data mask function by DQM.
• Internal dual banks operation.
• Burst Read Single Write operation.
• Special Function Support.
-PASR (Partial Array Self Refresh)
-Auto TCSR(Temperature Compensated Self Refresh)
• Automatic precharge, includes CONCURRENT
Auto Precharge Mode and controlled Precharge
