DTM64385A 16GB - 240-Pin 2Rx4 Registered ECC DDR3 DIMM Identification DTM64385A 1Gx72 16GB 2Rx4 PC3-12800R-11-11-E2 Performance range Clock / Module Speed / CL-tRCD -tRP 800 MHz / PC3-12800 / 11-11-11 667 MHz / PC3-10600 / 10-10-10 667 MHz / PC3-10600 / 9-9-9 533 MHz / PC3-8500 / 8-8-8 533 MHz / PC3-8500 / 7-7-7 400 MHz / PC3-6400 / 6-6-6 Features Description 240-pin JEDEC-compliant DIMM, 133.35 mm wide by 30 mm high DTM64385A is a registered 2Gx72 memory module, which conforms to JEDEC's DDR3, PC3-12800 standard. The assembly is Dual-Rank. Each Rank is comprised of eighteen Samsung 1Gx4 DDR3-1600 SDRAMs. One 2Kbit EEPROM is used for Serial Presence Detect and a combination register/PLL, with Address and Command Parity, is also used. Operating Voltage: 1.5V ±0.075 I/O Type: SSTL_15 On-board I2C temperature sensor with integrated Serial PresenceDetect (SPD) EEPROM Data Transfer Rate: 12.8 Gigabytes/sec Both output driver strength and input termination impedance are programmable to maintain signal integrity on the I/O signals in a Fly-by topology. A thermal sensor accurately monitors the DIMM module and can prevent exceeding the maximum operating temperature of 95C. Data Bursts: 8 and burst chop 4 mode ZQ Calibration for Output Driver and On-Die Termination (ODT) Programmable ODT / Dynamic ODT during Writes Programmable CAS Latency: 6, 7, 8, 9, 10, and 11 Bi-directional Differential Data Strobe signals SDRAM Addressing (Row/Col/Bank): 16/11/3 Fully RoHS Compliant Pin Configuration Front Side Pin Description Back Side Name Function 1 VREFDQ 31 DQ25 61 A2 91 DQ41 121 VSS 151 VSS 181 A1 211 VSS CB[7:0] Data Check Bits 2 VSS 32 VSS 62 VDD 92 VSS 122 DQ4 152 DQS12 182 VDD 212 DQS14 DQ[63:0] Data Bits 3 4 5 6 33 34 35 36 63 CK1* 64 /CK1* 65 VDD 66 VDD 93 94 95 96 /DQS5 DQS5 VSS DQ42 123 124 125 126 153 154 155 156 183 184 185 186 213 214 215 216 DQS[17:0], /DQS[17:0] CK[1:0], /CK[1:0] CKE[1:0] /CAS Differential Data Strobes Differential Clock Inputs Clock Enables Column Address Strobe 7 DQS0 37 DQ27 8 VSS 38 VSS 9 DQ2 39 CB0 67 VREFCA 68 PAR_IN 69 VDD 97 98 99 DQ43 VSS DQ48 127 VSS 128 DQ6 129 DQ7 157 VSS 158 CB4 159 CB5 187 /EVENT 188 A0 189 VDD 217 VSS 218 DQ52 219 DQ53 /RAS /S[3:0] /WE Row Address Strobe Chip Selects Write Enable 10 DQ3 11 VSS 12 DQ8 40 CB1 41 VSS 42 /DQS8 70 A10/AP 71 BA0 72 VDD 100 DQ49 101 VSS 102 /DQS6 130 VSS 131 DQ12 132 DQ13 160 VSS 161 DQS17 162 /DQS17 190 BA1 191 VDD 192 /RAS 220 VSS 221 DQS15 222 /DQS15 A[15:0] BA[2:0] ODT[1:0] Address Inputs Bank Addresses On Die Termination Inputs 13 DQ9 43 DQS8 73 /WE 103 DQS6 133 VSS 163 VSS 193 /S0 223 VSS SA[2:0] SPD Address 14 15 16 17 44 45 46 47 74 75 76 77 104 105 106 107 134 135 136 137 164 165 166 167 194 195 196 197 224 225 226 227 SCL SDA /EVENT /RESET SPD Clock Input SPD Data Input/Output Temperature Sensing Reset for register and DRAMs DQ0 DQ1 VSS /DQS0 VSS /DQS1 DQS1 VSS /DQS3 DQS3 VSS DQ26 VSS CB2 CB3 VSS /CAS VDD /S1 ODT1 18 DQ10 19 DQ11 20 VSS 48 VTT 49 VTT 50 CKE0 21 DQ16 51 VDD 81 DQ32 22 DQ17 52 BA2 82 DQ33 23 24 25 26 27 53 54 55 56 57 83 84 85 86 87 113 114 115 116 117 VSS /DQS2 DQS2 VSS DQ18 28 DQ19 29 VSS 30 DQ24 /ERR_OUT VDD A11 A7 VDD 58 A5 59 A4 60 VDD VSS DQ50 DQ51 VSS 78 VDD 108 DQ56 79 /S2, NC 109 DQ57 80 VSS 110 VSS VSS /DQS4 DQS4 VSS DQ34 88 DQ35 89 VSS 90 DQ40 DQ5 VSS DQS9 /DQS9 DQS10 /DQS10 VSS DQ14 /DQS12 VSS DQ30 DQ31 CB6 CB7 VSS NC (TEST) VDD CK0 /CK0 VDD VDD ODT0 A13 VDD /DQS14 VSS DQ46 DQ47 DQ54 DQ55 VSS DQ60 138 DQ15 139 VSS 140 DQ20 168 /RESET 169 CKE1 170 VDD 198 /S3, NC 199 VSS 200 DQ36 228 DQ61 229 VSS 230 DQS16 PAR_IN /ERR_OUT A12/BC Parity bit for Addr/Ctrl Error bit for Parity Error Combination input: Addr12/Burst Chop 111 /DQS7 141 DQ21 171 A15 201 DQ37 231 /DQS16 A10/AP Combination input: Addr10/Auto-precharge 112 DQS7 142 VSS 172 A14 202 VSS 232 VSS VSS Ground 143 144 145 146 147 173 174 175 176 177 203 204 205 206 207 233 234 235 236 237 VDD VDDSPD VREFDQ VREFCA VTT Power SPD EEPROM Power Reference Voltage for DQ’s Reference Voltage for CA Termination Voltage NC No Connection * not used VSS DQ58 DQ59 VSS SA0 118 SCL 119 SA2 120 VTT DQS11 /DQS11 VSS DQ22 DQ23 148 VSS 149 DQ28 150 DQ29 VDD A12/BC A9 VDD A8 178 A6 179 VDD 180 A3 DQS13 /DQS13 VSS DQ38 DQ39 208 VSS 209 DQ44 210 DQ45 Document 06976, Revision A, 10-Nov-11, Dataram Corporation 2011 DQ62 DQ63 VSS VDDSPD SA1 238 SDA 239 VSS 240 VTT Page 1 DTM64385A 16GB - 240-Pin 2Rx4 Registered ECC DDR3 DIMM Front view 133.35 [5.250] 9.50 [0.374] 30.00 [1.181] 17.30 [0.681] 5.00 [0.197] 5.175 [0.204] 47.00 [1.850] 71.00 [2.795] 2.50 [0.098] 123.00 [4.843] Back view Side view 3.94 Max [0.155] Max 4.00 Min [0.157] Min 1.27 ±.10 [0.0500 ±0.0040] Notes Tolerances on all dimensions except where otherwise indicated are ±.13 (.005).
