Description:

The VG3617161BT is CMOS Synchronous Dynamic RAM organized as 524,288-word x 16-bit x 2-bank.  It is fabricated with an advanced submicron CMOS technology and designed to operate from a single 3.3V power supply.   This SDRAM is delicately designed with performance concern for current high-speed application.  Programmable CAS Latency and Burst Length make it possible to be used in widely various domains. It is packaged by using JEDEC standard pintouts and standard plastic 50-pin TSOP II.

Features:

• Single 3.3V +/- 0.3V power supply
• Clock Frequency: 166MHz, 143MHz, 125MHz, 100MHz
• Fully synchronous with all signals referenced to a postive clock edge
• Programmable CAS latency (2,3)
• Programmable burst length (1,2,4,8, & full page)
• Programmable wrap sequence (Sequential/Interleave)
• Automatic precharge and controlled precharge
• Auto refresh and self refresh modes
• Dual internal banks controlled by A11 (Bank select)
• Simultaneous and independent two bank operation
• I/O level: LVTTL interface
• Random column access in every cycle
• X16 organization
• Byte control by LDQM and UDQM
• 2048 refresh cycles/32ms
• Burst termination by burst stop and precharge command
