PC2-6400 CL5 200-Pin SODIMM Kit

DESCRIPTION:

Kingston's KHX6400S2ULK2/2G is a kit of two 128M x 64-bit 1GB (1024MB) CL5 SDRAM
(Synchronous DRAM) memory modules. Each module is based on eight 128M x 8-bit DDR2 FBGA
components. Total kit capacity is 4GB (4096MB). The SPDs are programmed to JEDEC ultra low
latency timing of 4-4-4-12 at 1.8V. Each 200-pin SODIMM uses gold contact fingers and requires
+1.8V. The electrical and mechanical specifications are as follows:

FEATURES:

Power supply : Vdd: 1.8V ± 0.1V, Vddq: 1.8V ± 0.1V
Double-data-rate architecture; two data transfers per clock cycle
Bidirectional data strobe(DQS)
Differential clock inputs(CK and CK)
DLL aligns DQ and DQS transition with CK transition
Programmable Read latency 4, 3 (clock)
Burst Length: 4, 8 (Interleave/nibble sequential)
Programmable Burst type (sequential & interleave)
Timing Reference: 4-4-4-12 at +1.8V
Edge aligned data output, center aligned data input
Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)
Serial presence detect with EEPROM
PCB : Height 1.180” (30.00mm), double sided component

PERFORMANCE:

Clock Cycle Time (tCK) CL=4 2.5ns (min.) / 8ns (max.)
Row Cycle Time (tRC) 57.5ns (min.)
Refresh to Active/Refresh Command Time (tRFC) 127.5ns
Row Active Time (tRAS) 45ns (min.) / 70,000ns (max.)
Single Power Supply of +1.8V (+/- .1V)
Power TBD W (operating per module)
UL Rating 94 V - 0

Operating Temperature 0o C to 55o C
Storage Temperature -55o C to +125o C
