Copper Lead Frame

54-Pin TSOPII

SDRAM Products

FEATURES

BENEFITS

• Clock frequency: up to 133 MHz

• Enhanced Long-term reliability with copper

lead frames

• Configurations: 32Mx16, 16Mx16, 8Mx16 & 4Mx16

• Superior thermal conductivity improvement:

170 W/m*K vs. 14 W/m*K (a 12X difference)

• Fully synchronous; all signals referenced to a

positive clock edge

• Internal pipelined operation; column address can be

changed every clock cycle

•

θ ja and jc characteristics provide up to 3X

advantage of heat dissipation capability

versus parts with alloy 42 lead frames

• Internal banks for hiding row access/precharge

• Power supply: +3.3V +/-0.3V

• Heat dissipated from the die faster makes it

run cooler, leading to longer life

• LVTTL interface

• Solder joint reliability vastly improved.

- CTE of Copper (17 ppm/ ^oC), matches the

CTE of Typical FR4 PWBs (15-17 ppm/ ^oC),

whereas CTE of Alloy 42 (5 ppm/ ^oC),

is a mismatch

• Programmable burst length (1, 2, 4, 8, full page)

• Programmable burst sequence: Sequential/Interleave

• Auto Refresh (CBR)

• Self Refresh Mode (/IT)

64ms, 8,192 cycle refresh (/IT)

<24ms, 8,192 cycle refresh (/XT)

• RoHS Version (NiPdAu plating)

- Most preferred for elimination of risk for

whisker growth

• Write recovery (tWR = “2 CLK”)

• Random column address every clock cycle

• Programmable CAS latency (2, 3 clocks)

• Over broader Military and Industrial

temperature ranges, the above benefits are

even more important

• Burst read/write and burst read/single write

operations capability

• Burst termination by burst stop and precharge command

APPLICATIONS

Examples Include:

• Available in 54-pin TSOP-II, choice of lead frame:

- Copper lead frame

- Alloy 42 lead frame

• Military, Aerospace, Avionics

• Operating Temperature Range:

Industrial: -40^oC to +85^oC

• Cellular Base Stations

• Gas / Oil Exploration

• Engine Control

Military:

-55^oC to +125^oC

• Pb/Sn finish or RoHS available

• On-Board Flight Computers

• Radar / Sonar

• 100% product screened at temperature extremes & Vcc

extremes
