NOVEMBER 2013
DEVICE OVERVIEW
FEATURES
• Clock frequency: 200, 166, 143 MHz
• Fully synchronous; all signals referenced to a
positive clock edge
• Internal bank for hiding row access/precharge
• Power supply: Vdd/Vddq = 2.3V-3.6V
IS42/45SxxxxxD - Vdd/Vddq = 3.3V
IS42/45RxxxxxD - Vdd/Vddq = 2.5
• LVTTL interface
• Programmable burst length
– (1, 2, 4, 8, full page)
• Programmable burst sequence:
Sequential/Interleave
• Auto Refresh (CBR)
• Self Refresh
• 8K refresh cycles every 64 ms
• 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
• Packages:
x8/x16: 54-pin TSOP-II, 54-ball TF-BGA (x16 only)
x32: 90-ball TF-BGA, 86-pin TSOP-ll
• Temperature Range:
Commercial (0oC to +70oC)
Industrial (-40oC to +85oC)
Automotive, A1 (-40oC to +85oC)
Automotive, A2 (-40oC to +105oC)
ISSI's 512Mb Synchronous DRAM achieves high-speed
data transfer using pipeline architecture. All inputs and
outputs signals refer to the rising edge of the clock input.
The 512Mb SDRAM is organized as follows.
