VG3617161BT

VIS Description VG3617161BT 16Mb CMOS Synchronous Dynamic RAM 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 pinouts and standard plastic 50-pin TSOP II. Features Single 3.3V +/- 0.3V power supply Clock Frequency: 200MHz, 183MHz, 166MHz, 143MHz, 125MHz Fully synchronous with all signals referenced to a positive clock edge Programmable CAS Iatency (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 Document:1G5-0150 Rev.4 Page 1 VIS Pin Configuration VG3617161BT 16Mb CMOS Synchronous Dynamic RAM 50-Pin Plastic TSOP(II)(400 mil) VDD DQ0 DQ1 1 2 3 4 5 6 7 50 49 48 47 46 45 44 VSS DQ15 DQ14 VSSQ DQ2 DQ3 VSSQ DQ13 DQ12 VDDQ DQ4 DQ5 ...
