Memory Module Specifications KVR1066D3N7/4G 4GB 2Rx8 512M x 64-Bit PC3-8500 CL7 240-Pin DIMM 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 SPECIFICATIONS This document describes ValueRAM's 512M x 64-bit (4GB) CL(IDD) 7 cycles DDR3-1066 CL7 SDRAM (Synchronous DRAM), 2Rx8 memory Row Cycle Time (tRCmin) 50.63ns (min.) module, based on sixteen 256M x 8-bit DDR3-1066 FBGA Refresh to Active/Refresh Command Time (tRFCmin) 160ns (min.) components. The SPD is programmed to JEDEC standard latency DDR3-1066 timing of 7-7-7 at 1.5V. This 240-pin DIMM Row Active Time (tRASmin) 37.5ns (min.) uses gold contact fingers. The electrical and mechanical Power (Operating) specifications are as follows: 1.320 W* UL Rating 94 V - 0 Operating Temperature 0o C to 85o C FEATURES Storage Temperature -55o C to +100o C * JEDEC standard 1.5V (1.425V ~1.575V) Power Supply *Power will vary depending on the SDRAM used. * 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 * 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 85C, 3.9us at 85C < TCASE < 95C * Asynchronous Reset * PCB: Height 1.18" (30mm), double sided component Continued >> Document No. VALUERAM0789-001.C00 08/17/11 Page 1 MODULE DIMENSIONS: T E C H N O L O G Y 133.35 Units: millimeters 30.00 18.80 15.80 11.00 8.00 54.70 0.00 0.00 Document No. VALUERAM0789-001.C00 Page 2
