IC42S16400A General Description
The IC42S16400A are high-speed 67,108,864-bit syn-chronous dynamic random-access memories, orga-nized as 1,048,576 x 16 x 4 (word x bit x bank), respectively.
The synchronous DRAMs achieved high-speed data transfer using the pipeline architecture and clock frequency up to 166MHz for -6. All input and outputs are synchronized with the positive edge of the clock.The synchronous DRAMs are compatible with Low Voltage TTL (LVTTL).These products are packaged in 54-pin TSOP-2 and 60ball(64M) VF-BGA.
