描述 Description

DESCRIPTION
ICSI's 16Mb Synchronous DRAM IC42S16100 is organized as a 524,288-word x 16-bit x 2-bank for improved performance. The synchronous DRAMs achieve high-speed data transfer using pipeline architecture. All inputs and outputs signals refer to the rising edge of the clock input.FEATURES
? Clock frequency: 200, 166, 143 MHz
? Fully synchronous; all signals referenced to a positive clock edge
? Two banks can be operated simultaneously and independently
? Dual internal bank controlled by A11 (bank select)
? Single 3.3V power supply
? LVTTL interface
? Programmable burst length
? – (1, 2, 4, 8, full page)
? Programmable burst sequence: Sequential/Interleave
? Auto refresh, self refresh
? 4096 refresh cycles every 64 ms
? Random column address every clock cycle
? Programmable CASlatency (2, 3 clocks)
? Burst read/write and burst read/single write operations capability
? Burst termination by burst stop and precharge command
? Byte controlled by LDQM and UDQM
? Package 400mil 50-pin TSOP-2
? Pb(lead)-free package is available
