Sequential/Interleave
• Self refresh modes
• Auto refresh (CBR)
• 4096 refresh cycles every 64 ms (Com, Ind, A1
grade) or 16ms (A2 grade)
• Random column address every clock cycle
• Programmable CAS latency (2, 3 clocks)
• Burst read/write and burst read/single write
operations capability
• Burst termination by burst stop and precharge
command

Automotive Grade A2 (-40oC to +105oC)
OVERVIEW
ISSI's 64Mb Synchronous DRAM is organized as 1,048,576
bits x 16-bit x 4-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.
