IS42S16400N-7B2LI 特徵

Clock frequency: 200, 166, 143, 133 MHz ISSI's 64Mb Synchronous DRAM is organized as 1,048,576 bits x 16-bit x 4-bank for improved performance. The
Fully synchronous; all signals referenced to a synchronous DRAMs achieve high-speed data transfer positive clock edge using pipeline architecture. All inputs and outputs signals
Internal bank for hiding row access/precharge refer to the rising edge of the clock input.
Single 3.3V power supply
LVTTL interface
