SYNCHRONOUS DYNAMIC RAM  
MAY 2007  
FEATURES  
OVERVIEW  
ISSI's64MbSynchronousDRAMIS42S16400Bisorganized  
as 1,048,576 bits x 16-bit x 4-bank for improved  
performance.ThesynchronousDRAMsachievehigh-speed  
data transfer using pipeline architecture. All inputs and  
outputs signals refer to the rising edge of the clock input.  
• Clock frequency: 166, 143 MHz  
• Fully synchronous; all signals referenced to a  
positive clock edge  
• Internal bank for hiding row access/precharge  
• Single 3.3V power supply  
• LVTTL interface  
PIN CONFIGURATIONS  
54-Pin TSOP (Type II)  
• Programmable burst length
