DRAM, SDR, 256 Mbit, 16M x 16bit, 143 MHz, TSOP-II, 54 Pins Product Overview The IS42S16160G-7TLI is a 256Mb Synchronous DRAM achieves high-speed data transfer using pipeline architecture. All inputs and outputs signals refer to the rising edge of the clock input. The 256Mb SDRAM is organized as 4M x16x4 banks, 54-pin TSOPII and 54-ball BGA. The 256Mb SDRAM is a high speed CMOS, dynamic random-access memory designed to operate in 3.3V Vdd and 3.3V Vddq memory systems containing 268,435,456 bits. Internally configured as a quad-bank DRAM with a synchronous interface. Each 67,108,864-bit bank is organized as 8,192 rows by 512 columns by 16 bits or 8,192 rows by 1,024 columns by 8 bits. The 256Mb SDRAM includes an AUTO REFRESH MODE and a power-saving, power-down mode. All signals are registered on the positive edge of the clock signal, CLK. All inputs and outputs are LVTTL compatible. 143MHz Clock frequency 7ns Speed Fully synchronous, all signals referenced to a positive clock edge Internal bank for hiding row access/precharge 3.3 ±0.3V Single power supply LVTTL interface Programmable burst length - 1, 2, 4, 8, full page Sequential/Interleave programmable burst sequence Auto refresh (CBR) Self refresh 8K Refresh cycles every 16ms (A2 grade) or 64ms (commercial, industrial, A1 grade) Random column address every clock cycle Programmable CAS latency - 2, 3 clocks Burst read/write and burst read/single write operations capability Burst termination by burst stop and precharge command Applications Industrial, Commercial, Computers & Computer Peripherals Product Information DRAM Type: SDR Access Time: 7ns DRAM Density: 256Mbit DRAM Memory Configuration: 16M x 16bit Clock Frequency: 143MHz No. of Pins: 54Pins Memory Case Style: TSOP-II Supply Voltage Nom: 3.3V Operating Temperature Min: -40°C Operating Temperature Max: 85°C IC Interface Type: LVTTL Product Range: IS42S MSL: MSL 3 - 168 hours
