PC3-8500 CL7 240-Pin DIMM Kit

Important Information: The module defined in this data sheet is one of several configurations available under
this part number. While all configurations are compatible, the DRAM combination and/or the module height may
vary from what is described here.

DESCRIPTION

ValueRAM's KVR1066D3S8N7K2/4G is a kit of two 256M x 64­bit (2GB) DDR3-1066 CL7 SDRAM (Synchronous DRAM), 1Rx8
memory modules, based on eight 256M x 8-bit FBGA compo­nents per module. Total kit capacity is 4GB. The SPD's are
programmed to JEDEC standard latency DDR3-1066 timing of
7-7-7 at 1.5V. Each 240-pin DIMM uses gold contact fingers.
The electrical and mechanical specifications are as follows:

FEATURES

• JEDEC standard 1.5V (1.425V ~1.575V) Power Supply

• VDDQ = 1.5V (1.425V ~ 1.575V)

• 533MHz fCK for 1066Mb/sec/pin

• 8 independent internal bank

• Programmable CAS Latency: 8, 7, 6

• Programmable Additive Latency: 0, CL - 2, or CL - 1 clock

• Programmable CAS Write Latency(CWL) = 6 (DDR3-1066)

• 8-bit pre-fetch

SPECIFICATIONS

CL(IDD) 7 cycles
Row Cycle Time (tRCmin) 50.63ns (min.)
Refresh to Active/Refresh 160ns (min.)

Command Time (tRFCmin)
Row Active Time (tRASmin) 37.5ns (min.)
Power (Operating) 0.725 W* (per module)

UL Rating 94 V - 0
Operating Temperature 0
Storage Temperature -55o C to +100o C

*Power will vary depending on the SDRAM used.

o

C to 85o C

• Burst Length: 8 (Interleave without any limit, sequential with

starting address “000” only), 4 with tCCD = 4 which does not
allow seamless read or write [either on the fly using A12 or
MRS]

• Bi-directional Differential Data Strobe

• Internal(self) calibration : Internal self calibration through ZQ

pin (RZQ : 240 ohm ± 1%)

• On Die Termination using ODT pin

• Average Refresh Period 7.8us at lower than TCASE 85°C,

3.9us at 85°C < TCASE < 95°C

• Asynchronous Reset

• PCB Height: 1.18” (30mm), single sided component
