IS42S16100A1 - ISSI

IS42S16100A1 512K Words x 16 Bits x 2 Banks (16-MBIT) SYNCHRONOUS DYNAMIC RAM

ISSI’s 16Mb Synchronous DRAM IS42S16100A1 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. PIN CONFIGURATIONS 50-Pin TSOP (Type II) VDD DQ0 DQ1 GNDQ DQ2 DQ3 VDDQ DQ4 DQ5 GND.
