DESCRIPTION The H5TQ2G43AMP-xxX and H5TQ2G83AMP-xxX are a 2,147,483,648-bit CMOS Double Data Rate III (DDR3) Synchronous DRAM, ideally suited for the main memory applications which requires large memory density and high bandwidth. Hynix 2Gb DDR3 SDRAMs offer fully synchronous operations referenced to both rising and falling edges of the clock. While all addresses and control inputs are latched on the rising edges of the CK (falling edges of the CK), Data, Data strobes and Write data masks inputs are sampled on both rising and falling edges of it. The data paths are internally pipelined and 8-bit prefetched to achieve very high bandwidth. 1.1 Device Features and Ordering Information 1.1.1 FEATURES * VDD=VDDQ=1.5V +/- 0.075V * Fully differential clock inputs (CK, CK) operation * Programmable burst length 4/8 with both nibble sequential and interleave mode * Differential Data Strobe (DQS, DQS) * BL switch on the fly * On chip DLL align DQ, DQS and DQS transition with CK transition * 8banks * DM masks write data-in at the both rising and falling edges of the data strobe * JEDEC standard 78ball FBGA(x4/x8) * All addresses and control inputs except data, data strobes and data masks latched on the rising edges of the clock * Dynamic On Die Termination supported * Programmable CAS latency 5, 6, 7, 8, 9, 10, and (11) supported * ZQ calibration supported * Programmable additive latency 0, CL-1, and CL-2 supported * Write Levelization supported * Programmable CAS Write latency (CWL) = 5, 6, 7, 8 * 8K refresh cycles /64ms * Driver strength selected by EMRS * Asynchronous RESET pin supported * TDQS (Termination Data Strobe) supported (x8 only) * Auto Self Refresh supported * On Die Thermal Sensor supported (JEDEC optional) * 8 bit pre-fetch 1.1.2 ORDERING INFORMATION Part No. Configuration H5TQ2G43AMP-xx*X 256M x 4 H5TQ2G83AMP-xx*X 128M x 8 1.1.3 OPERATING FREQUENCY Package Grade 78ball FBGA * xx means Binning grade (Speed/IDD...) -G8 -H9 Frequency [MHz] CL5 CL6 CL7 CL8 CL9 CL10 O Remark (CL-tRCD-tRP) O O DDR3-1066 8-8-8 O O DDR3-1333 9-9-9 * X means Power Consumption & Temperature Rev. 0.1 /Aug 2008 5 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC 1.2 Package Ball out 1.2.1 x4 Package Ball out 1 2 3 VSS VDD NC B VSS VSSQ C VDDQ DQ2 D VSSQ NC E VREFDQ F G A 4 5 6 7 8 9 NC VSS VDD A DQ0 DM VSSQ VDDQ B DQS DQ1 DQ3 VSSQ C DQS VDD VSS VSSQ D VDDQ NC NC NC VDDQ E ODT1 VSS RAS CK VSS CKE1 F ODT0 VDD CAS CK VDD CKE0 G H H CS1 CS0 WE A10/AP ZQ0 ZQ1 J VSS BA0 BA2 A15 VREFCA VSS J K VDD A3 A0 A12/BC BA1 VDD K L VSS A5 A2 A1 A4 VSS L M VDD A7 A9 A11 A6 VDD M N VSS RESET A13 A14 A8 VSS N 1 2 3 7 8 9 4 5 6 Note : Green NC balls indicate mechanical support balls with no internal connection 1 2 3 7 8 9 A B C D E F G H J K (Top View: See the balls through the Package) Populated ball Ball not populated L M N Back View Populated ball Ball not populated Rev. 0.1 /Aug 2008 6 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC 1.2.2 x8 Package Ball out 1 2 3 4 5 6 7 8 9 A VSS VDD NC NU/TDQS VSS VDD A B VSS VSSQ DQ0 DM/TDQS VSSQ VDDQ B C VDDQ DQ2 DQS DQ1 DQ3 VSSQ C D VSSQ DQ6 DQS VDD VSS VSSQ D E VREFDQ VDDQ DQ4 DQ7 DQ5 VDDQ E F ODT1 VSS RAS CK VSS CKE1 F G ODT0 VDD CAS CK VDD CKE0 G H H CS1 CS0 WE A10/AP ZQ0 ZQ1 J VSS BA0 BA2 A15 VREFCA VSS J K VDD A3 A0 A12/BC BA1 VDD K L VSS A5 A2 A1 A4 VSS L M VDD A7 A9 A11 A6 VDD M N VSS RESET A13 A14 A8 VSS N 1 2 3 7 8 9 4 5 6 Note : Green NC balls indicate mechanical support balls with no internal connection 1 2 3 7 8 9 A B C D E F G H J K (Top View: See the balls through the Package) Populated ball Ball not populated L M N Rev. 0.1 /Aug 2008 7 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC 1.3 ROW AND COLUMN ADDRESS TABLE 1Gb Configuration # of Banks Bank Address Auto precharge BL switch on the fly Row Address Column Address Page size 1 256Mb x 4 128Mb x 8 64Mb x 16 8 BA0 - BA2 A10/AP A12/BC A0 - A13 A0 - A9,A11 1 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A13 A0 - A9 1 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A12 A0 - A9 2 KB 512Mb x 4 256Mb x 8 128Mb x 16 8 BA0 - BA2 A10/AP A12/BC A0 - A14 A0 - A9,A11 1 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A14 A0 - A9 1 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A13 A0 - A9 2 KB 1Gb x 4 512Mb x 8 256Mb x 16 8 BA0 - BA2 A10/AP A12/BC A0 - A15 A0 - A9,A11 1 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A15 A0 - A9 1 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A14 A0 - A9 2 KB 2Gb x 4 1Gb x 8 512Mb x 16 8 BA0 - BA2 A10/AP A12/BC A0 - A15 A0 - A9, A11, A13 2 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A15 A0 - A9, A11 2 KB 8 BA0 - BA2 A10/AP A12/BC A0 - A15 A0 - A9 2 KB 2Gb Configuration # of Banks Bank Address Auto precharge BL switch on the fly Row Address Column Address Page size 1 4Gb Configuration # of Banks Bank Address Auto precharge BL switch on the fly Row Address Column Address Page size 1 8Gb Configuration # of Banks Bank Address Auto precharge BL switch on the fly Row Address Column Address Page size 1 Note1 : Page size is the number of bytes of data delivered from the array to the internal sense amplifiers when an ACTIVE command is registered. Page size is per bank, calculated as follows: page size = 2 COLBITS * ORG / 8 where COLBITS = the number of column address bits, ORG = the number of I/O (DQ) bits Rev. 0.1 /Aug 2008 8 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC 1.4 Pin Functional Description Input / output functional description Symbol Type Function CK, CK Input Clock: CK and CK are differential clock inputs. All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK. CKE Input Clock Enable: CKE HIGH activates, and CKE Low deactivates, internal clock signals and device input buffers and output drivers. Taking CKE Low provides Precharge Power-Down and SelfRefresh operation (all banks idle), or Active Power-Down (row Active in any bank). CKE is asynchronous for Self-Refresh exit. After VREFCA and VREFDQ have become stable during the power on and initialization sequence, they must be maintained during all operations (including Self-Refresh). CKE must be maintained high throughout read and write accesses. Input buffers, excluding CK, CK, ODT and CKE are disabled during power-down. Input buffers, excluding CKE, are disabled during Self-Refresh. CS Input Chip Select: All commands are masked when CS is registered HIGH. CS provides for external Rank selection on systems with multiple Ranks. CS is considered part of the command code. ODT Input On Die Termination: ODT (registered HIGH) enables termination resistance internal to the DDR3 SDRAM. When enabled, ODT is only applied to each DQ, DQS, DQS and DM/TDQS, NU/ TDQS (When TDQS is enabled via Mode Register A11=1 in MR1) signal for x4/x8 configurations. For x16 configuration ODT is applied to each DQ, DQSU, DQSU, DQSL, DQSL, DMU, and DML signal. The ODT pin will be ignored if MR1 is programmed to disable ODT. RAS. CAS. WE Input Command Inputs: RAS, CAS and WE (along with CS) define the command being entered. DM, (DMU), (DML) Input Input Data Mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH coincident with that input data during a Write access. DM is sampled on both edges of DQS. For x8 device, the function of DM or TDQS/TDQS is enabled by Mode Register A11 setting in MR1. BA0 - BA2 Input Bank Address Inputs: BA0 - BA2 define to which bank an Active, Read, Write or Precharge command is being applied. Bank address also determines if the mode register or extended mode register is to be accessed during a MRS cycle. Input Address Inputs: Provide the row address for Active commands and the column address for Read/Write commands to select one location out of the memory array in the respective bank. (A10/AP and A12/BC have additional functions, see below). The address inputs also provide the op-code during Mode Register Set commands. A10 / AP Input Auto-precharge: A10 is sampled during Read/Write commands to determine whether Autoprecharge should be performed to the accessed bank after the Read/Write operation. (HIGH: Autoprecharge; LOW: no Autoprecharge).A10 is sampled during a Precharge command to determine whether the Precharge applies to one bank (A10 LOW) or all banks (A10 HIGH). If only one bank is to be precharged, the bank is selected by bank addresses. A12 / BC Input Burst Chop: A12 / BC is sampled during Read and Write commands to determine if burst chop (on-the-fly) will be performed. (HIGH, no burst chop; LOW: burst chopped). See command truth table for details. Input Active Low Asynchronous Reset: Reset is active when RESET is LOW, and inactive when RESET is HIGH. RESET must be HIGH during normal operation. RESET is a CMOS rail to rail signal with DC high and low at 80% and 20% of VDD, i.e. 1.20V for DC high and 0.30V for DC low. A0 - A15 RESET Rev. 0.1 /Aug 2008 9 Symbol Type DQ Input / Output Data Input/ Output: Bi-directional data bus. Input / Output Data Strobe: output with read data, input with write data. Edge-aligned with read data, centered in write data. For the x16, DQSL corresponds to the data on DQL0-DQL7; DQSU corresponds to the data on DQU0-DQU7. The data strobe DQS, DQSL, and DQSU are paired with differential signals DQS, DQSL, and DQSU, respectively, to provide differential pair signaling to the system during reads and writes. DDR3 SDRAM supports differential data strobe only and does not support single-ended. Output Termination Data Strobe: TDQS/TDQS is applicable for x8 DRAMs only. When enabled via Mode Register A11 = 1 in MR1, the DRAM will enable the same termination resistance function on TDQS/TDQS that is applied to DQS/DQS. When disabled via mode register A11 = 0 in MR1, DM/TDQS will provide the data mask function and TDQS is not used. x4 DRAMs must disable the TDQS function via mode register A11 = 0 in MR1.

All DDR3 SDRAM commands are defined by states of CS, RAS, CAS, WE and CKE at the rising edge of the clock. The MSB of BA, RA and CA are device density and configuration dependant. 2. RESET is Low enable command which will be used only for asynchronous reset so must be maintained HIGH during any function. 3. Bank addresses (BA) determine which bank is to be operated upon. For (E)MRS BA selects an (Extended) Mode Register. 4. "V" means "H or L (but a defined logic level)" and "X" means either "defined or undefined (like floating) logic level". 5. Burst reads or writes cannot be terminated or interrupted and Fixed/on the Fly BL will be defined by MRS. 6. The Power Down Mode does not perform any refresh operation. 7. The state of ODT does not affect the states described in this table. The ODT function is not available during Self Refresh. 8. Self Refresh Exit is asynchronous. 9. VREF (Both VrefDQ and VrefCA) must be maintained during Self Refresh operation. 10. The No Operation command should be used in cases when the DDR3 SDRAM is in an idle or wait state. The purpose of the No Operation command (NOP) is to prevent the DDR3 SDRAM from registering any unwanted commands between operations. A No Operation command will not terminate a previous operation that is still executing, such as a burst read or write cycle. 11. The Deselect command performs the same function as No Operation command. 12. Refer to the CKE Truth Table for more detail with CKE transition.

CKE (N) is the logic state of CKE at clock edge N; CKE (N-1) was the state of CKE at the previous clock edge. 2. Current state is defined as the state of the DDR3 SDRAM immediately prior to clock edge N. 3. COMMAND (N) is the command registered at clock edge N, and ACTION (N) is a result of COMMAND (N), ODT is not included here. 4. All states and sequences not shown are illegal or reserved unless explicitly described elsewhere in this document. 5. The state of ODT does not affect the states described in this table. The ODT function is not available during Self-Refresh. 6. tCKEmin of [TBD] clocks means CKE must be registered on [TBD] consecutive positive clock edges. CKE must remain at the valid input level the entire time it takes to achieve the [TBD] clocks of registration. Thus, after any CKE transition, CKE may not transition from its valid level during the time period of tIS + [TBD] + tIH. 7. DESELECT and NOP are defined in the Command Truth Table. 8. On Self-Refresh Exit DESELECT or NOP commands must be issued on every clock edge occurring during the tXS period. Read or ODT commands may be issued only after tXSDLL is satisfied. 9. Self-Refresh mode can only be entered from the All Banks Idle state. 10. Must be a legal command as defined in the Command Truth Table. 11. Valid commands for Power-Down Entry and Exit are NOP and DESELECT only. 12. Valid commands for Self-Refresh Exit are NOP and DESELECT only. 13. Self-Refresh can not be entered during Read or Write operations. For a detailed list of restrictions see 8.2.1 on page 44. 14. The Power-Down does not perform any refresh operations. 15. "X" means "don't care" (including floating around VREF) in Self-Refresh and Power-Down. It also applies to Address pins. 16. VREF (Both Vref_DQ and Vref_CA) must be maintained during Self-Refresh operation. 17. If all banks are closed at the conclusion of the read, write or precharge command, then Precharge Power-Down is entered, otherwise Active Power-Down is entered. 18. `Idle state' is defined as all banks are closed (tRP, tDAL, etc. satisfied), no data bursts are in progress, CKE is high, and all timings from previous operations are satisfied (tMRD, tMOD, tRFC, tZQinit, tZQoper, tZQCS, etc.) as well as all Self-Refresh exit and Power-Down Exit parameters are satisfied (tXS, tXP, tXPDLL, etc).

Operating Temperature TOPER is the case surface temperature on the center / top side of the DRAM. For measurement conditions, please refer to the JEDEC document JESD51-2. 2. The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported. During operation, the DRAM case temperature must be maintained between 0 - 85oC under all operating conditions. 3. Some applications require operation of the DRAM in the Extended Temperature Range between 85oC and 95oC case temperature. Full specifications are guaranteed in this range, but the following additional conditions apply: a) Refresh commands must be doubled in frequency, therefore reducing the Refresh interval tREFI to 3.9 s. (This double refresh requirement may not apply for some devices.) It is also possible to specify a component with 1X refresh (tREFI to 7.8s) in the Extended Temperature Range. Please refer to supplier data sheet and/or the DIMM SPD for option availability. b) If Self-Refresh operation is required in the Extended Temperature Range, then it is mandatory to either use the Manual Self-Refresh mode with Extended Temperature Range capability (MR2 A6 = 0b and MR2 A7 = 1b) or enable the optional Auto Self-Refresh mode (MR2 A6 = 1b and MR2 A7 = 0b). 4.2 RECOMMENDED DC OPERATING CONDITIONS Rating Symbol VDD VDDQ Parameter Units Notes 1.575 V 1,2 1.575 V 1,2 Min.

For DQ and DM, Vref = VrefDQ. For input any pins except RESET, Vref = VrefCA. 2. The "t.b.d." entries might change based on overshoot and undershoot specification. 3. The ac peak noise on VRef may not allow VRef to deviate from VRef(DC) by more than +/-1% VDD (for reference: approx. +/- 15 mV). 4. For reference: approx. VDD/2 +/- 15 mV. The dc-tolerance limits and ac-noise limits for the reference voltages VRefCA and VRefDQ are illustrated in below Figure. It shows a valid reference voltage VRef(t) as a function of time. (VRef stands for VRefCA and VRefDQ likewise). VRef(DC) is the linear average of VRef(t) over a very long period of time (e.g. 1 sec). This average has to meet the min/max requirements in Table 1.

STABLE is defined as inputs are stable at a HIGH or LOW level. FLOATING is defined as inputs are VREF = VDDQ / 2. SWITCHING is defined as described in the following 2 tables. Rev. 0.1 /Aug 2008 36 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC Definition of SWITCHING for Address and Command Input Signals SWITCHING for Address (row, column) and Command Signals (CS, RAS, CAS, WE) is defined as: Address (row, column) If not otherwise mentioned the inputs are stable at HIGH or LOW during 4 clocks and change then to the opposite value (e.g. Ax Ax Ax Ax Ax Ax Ax Ax Ax Ax Ax Ax ..... please see each IDDx definition for details Bank address If not otherwise mentioned the bank addresses should be switched like the row/column addresses - please see each IDDx definition for details Define D = {CS, RAS, CAS, WE } = {HIGH, LOW, LOW, LOW} Define D = {CS, RAS, CAS, WE } = {HIGH, HIGH,HIGH,HIGH} Define Command Background Pattern = D D D D D D D D D D D D ... Command (CS, RAS, CAS, WE) If other commands are necessary (e.g. ACT for IDD0 or Read for IDD4R), the Background Pattern Command is substituted by the respective CS, RAS, CAS, WE levels of the necessary command. See each IDDx definition for details and figures 1,2,3 as examples. Definition of SWITCHING for Data (DQ) SWITCHING for Data (DQ) is defined as Data DQ is changing between HIGH and LOW every other data transfer (once per clock) for DQ signals, which means that data DQ is stable during one clock; see each IDDx definition for exceptions from this rule and for further details. See figures 1,2,3 as examples. Data (DQ) Data Masking (DM) NO Switching; DM must be driven LOW all the time Timing parameters are listed in the following table: For IDD testing the following parameters are utilized.

The CL setting and CWL setting result in tCK(AVG).MIN and tCK(AVG).MAX requirements. When making a selection of tCK(AVG), both need to be fulfilled: Requirements from CL setting as well as requirements from CWL setting. 2. tCK(AVG).MIN limits: Since CAS Latency is not purely analog - data and strobe output are synchronized by the DLL - all possible intermediate frequencies may not be guaranteed. An application should use the next smaller JEDEC standard tCK(AVG) value (2.5, 1.875, 1.5, or 1.25 ns) when calculating CL [nCK] = tAA [ns] / tCK(AVG) [ns], rounding up to the next `Supported CL'. 3. tCK(AVG).MAX limits: Calculate tCK(AVG) = tAA.MAX / CLSELECTED and round the resulting tCK(AVG) down to the next valid speed bin (i.e. 3.3ns or 2.5ns or 1.875 ns or 1.25 ns). This result is tCK(AVG).MAX corresponding to CLSELECTED. 4. `Reserved' settings are not allowed. User must program a different value. 5. `Optional' settings allow certain devices in the industry to support this setting, however, it is not a mandatory feature. Refer to supplier's data sheet and SPD information if and how this setting is supported. 6.

For example, if the measured jitter into a DDR-800 SDRAM has tERR(mper),act,min = -172 ps and tERR(mper),act,max =+ 193 ps, then t DQSCK,min(derated) = tDQSCK,min - tERR(mper),act,max = -400 ps - 193 ps = - 593 ps and tDQSCK,max(derated) = tDQSCK,max - tERR(mper),act,min = 400 ps+ 172 ps = + 572 ps. Similarly, tLZ(DQ) for DDR3-800 derates to tLZ(DQ),min(derated) = - 800 ps 193 ps = - 993 ps and tLZ(DQ),max(derated) = 400 ps + 172 ps = + 572 ps. ( Caution on the min/max usage!) Note that tERR(mper),act,min is the minimum measured value of tERR(nper) where 2 <= n <=12, and tERR(mper),act,max is the maximum measured value of tERR(nper) where 2 <= n <= 12 Specific Note b When the device is operated with input clock jitter, this parameter needs to be derated by the actual tJIT(per),act of the input clock. ( output deratings are relative to the SDRAM input clock. ) For example, if the measured jitter into a DDR3-800 SDRAM has tCK(avg),act = 2500 ps, tJIT(per),act,min = - 72 ps and tJIT(per),act,max = + 93 ps, then tRPRE,min(derated) = tRPRE,min + tJIT(per),act,min = 0.9 x tCK(avg),act + tJIT(per),act,min(derated) = tRPRE,min + tJIT(per),act,min = 0.9 x tCK(avg),act + tJIT(per),act,min = 0.9 x 2500 ps - 72 ps =+ 2178 ps. Similarly, tQH,min(derated) = tQH,min + tJIT(per),act,min = 0.38 x tCK(avg),act + tJIT(per),act,min = 0.38 x 2500 ps 72 ps = + 878 ps. (Caution on the min/max usage!) Specific Note c These parameters are measured from a data strobe signal (DQS(L/U), DQS(L/U)) crossing to its respective clock signal (CK, CK) crossing. The spec values are not affected by the amount of clock jitter applied (i.e. tJIT(per), tJIT(cc), etc.), as these are relative to the clock signal crossing. That is, these parameters should be met whether clock jitter is present or not. Specific Note d These parameters are measured from a data signal (DM(L/U), DQ(L/U)0, DQ(L/U)1, etc.) transition edge to its respective data strobe signal (DQS(L/U), DQS(L/U)) crossing. Specific Note e For these parameters, the DDR3 SDRAM device supports tnPARAM [nCK] = RU{ tPARAM [ns] / tCK(avg) [ns] }, which is in clock cycles, assuming all input clock jitter specifications are satisfied.For example, the device will support tnRP = RU{tRP / tCK(avg)}, which is in clock cycles, if all input clock jitter specifications are met. This means: For DDR3-800 6-6-6, of which tRP = 15ns, the device will support tnRP = RU{tRP / tCK(avg)} = 6, as long as the input clock jitter specifications are met, i.e. Precharge command at Tm and Active command at Tm+6 is valid even if (Tm+6 - Tm) is less than 15ns due to input clock jitter. Specific Note f These parameters are specified per their average values, however it is understood that the following relationship between the average timing and the absolute instantaneous timing holds at all times. (Min and max of SPEC values are to be used for calculations in Table . Rev. 0.1 /Aug 2008 57 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC Timing Parameter Notes 1. Actual value dependant upon measurement level definitions which are TBD. 2. Commands requiring a locked DLL are: READ (and RAP) and synchronous ODT commands. 3. The max values are system dependent. 4. WR as programmed in mode register. 5. Value must be rounded-up to next higher integer value. 6. There is no maximum cycle time limit besides the need to satisfy the refresh interval, tREFI. 7. For definition of RTT turn-on time tAON See 4.2.2 "Timing Parameters" on page 93. 8. For definition of RTT turn-off time tAOF See 4.2.2 "Timing Parameters" on page 93. 9. tWR is defined in ns, for calculation of tWRPDEN it is necessary to round up tWR / tCK to the next integer. 10. WR in clock cycles as programmed in MR0. 11. The maximum postamble is bound by tHZDQS(max) 12. Output timing deratings are relative to the SDRAM input clock. When the device is operated with input clock jitter, this parameter needs to be derated by t.b.d. 13. Value is only valid for RON34 14. Single ended signal parameter. Refer to chapter for definition and measurement method. 15. tREFI depends on TOPER 16. tIS(base) and tIH(base) values are for 1V/ns CMD/ADD single-ended slew rate and 2V/ns CK, CK differential slew rate. Note for DQ and DM signals, VREF(DC) = VRefDQ(DC). For input only pins except RESET, VRef(DC) = VRefCA(DC). See "Address / Command Setup, Hold and Derating" on page 59. 17. tDS(base) and tDH(base) values are for 1V/ns DQ single-ended slew rate and 2V/ns DQS, DQS differential slew rate. Note for DQ and DM signals, VREF(DC) = VRefDQ(DC). For input only pins except RESET, VRef(DC) = VRefCA(DC). See "Data Setup, Hold and Slew Rate Derating" on page 67.. 18. Start of internal write transaction is definited as follows: For BL8 (fixed by MRS and on- the-fly): Rising clock edge 4 clock cycles after WL. For BC4 (on- the- fly): Rising clock edge 4 clock cycles after WL. For BC4 (fixed by MRS): Rising clock edge 2 clock cycles after WL. 19. The maximum preamble is bound by tLZDQS(min) 20. CKE is allowed to be registered low while operations such as row activation, precharge, autoprecharge or refresh are in progress, but power-down IDD spec will not be applied until finishing those operations. 21. Although CKE is allowed to be registered LOW after a REFRESH command once tREFPDEN(min) is satisfied, there are cases where additional time such as tXPDLL(min) is also required. 22. Defined between end of MPR read burst and MRS which reloads MPR or disables MPR function. 23. One ZQCS command can effectively correct a minimum of 0.5% (ZQCorrection)of RON and RTT impedance error within 64 nCK for all speed bins assuming the maximum sensitivities specified in the `Output Driver Voltage and Temperature Sensitivity' and `ODT Voltage and Temperature Sensitivity' tables. The appropriate interval between ZQCS commands can be determined from these tables and other application specific parameters. One method for calculating the interval between ZQCS commands, given the temperature ( Tdrifrate ) and voltage ( Vdriftrate ) drift rates that the SDRAM is subject to in the application, is illustrated. The interval could be defined by the following formula. Rev. 0.1 /Aug 2008 58 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC ZQCorrection -----------------------------------------------------------------------------------------------------------(Tsens x Tdriftrate)+( VSens x Vdriftrate) where TSens = max(dRTTdT, dRONdTM) and VSens = max(dRTTdV, dRONdVM) define the SDRAM temperature and voltage sensitivities. For example, if TSens = 1.5% / oC, VSens = 0.15% / mV, Tdriftrate = 1 oC / sec and Vdriftrate = 15 mV / sec, then the interval between ZQCS commands is calculated as : 0.5 ------------------------------------------------------ = 0.133 = 128ms (1.5 x 1)+(0.15 x 15) 24. n = from 13 cycles to 50 cycles. 25. tCH(abs) is the absolute instantaneous clock high pulse width, as measured from one rising edge to the following fall ing edge. 26. tCL(abs) is the absolute instantaneous clock low pulse width, as measured from one falling edge to the following rising edge. 27. The tIS(base) AC150 specifications are adjusted from the tIS(base) specification by adding an additional 100 ps of der ating to accommodate for the lower alternate threshold of 150 mV and another 25 ps to account for the earlier refer ence point [(175 mV - 150 mV) / 1 V/ns]. Address / Command Setup, Hold and Derating For all input signals the total tIS (setup time) and tIH (hold time) required is calculated by adding the data sheet tIS(base) and tIH(base) value (see Table 1) to the tIS and tIH derating value (see Table 2) respectively. Example: tIS (total setup time) = tIS(base) + tIS Setup (tIS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VREF(dc) and the first crossing of VIH(ac)min. Setup (tIS) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VREF(dc) and the first crossing of Vil(ac)max. If the actual signal is always earlier than the nominal slew rate line between shaded `VREF(dc) to ac region', use nominal slew rate for derating value (see Figure 2). If the actual signal is later than the nominal slew rate line anywhere between shaded `VREF(dc) to ac region', the slew rate of a tangent line to the actual signal from the ac level to dc level is used for derating value (see Figure 4). Hold (tIH) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of Vil(dc)max and the first crossing of VREF(dc). Hold (tIH) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of Vih(dc)min and the first crossing of VREF(dc). If the actual signal is always later than the nominal slew rate line between shaded `dc to VREF(dc) region', use nominal slew rate for derating value (see Figure 3). If the actual signal is earlier than the nominal slew rate line anywhere between shaded `dc to VREF(dc) region', the slew rate of a tangent line to the actual signal from the dc level to VREF(dc) level is used for derating value (see Figure 4). For a valid transition the input signal has to remain above/below VIH/IL(ac) for some time tVAC (see Table 4). Rev. 0.1 /Aug 2008 59 H5TQ2G43AMP-xxC H5TQ2G83AMP-xxC Although for slow slew rates the total setup time might be negative (i.e. a valid input signal will not have reached VIH/IL(ac) at the time of the rising clock transition) a valid input signal is still required to complete the transition and reach VIH/IL(ac). For slew rates in between the values listed in Table 2, the derating values may obtained by linear interpolation. These values are typically not subject to production test. They are verified by design and characterization.

Example: tDS (total setup time) = tDS(base) + DtDS. Setup (tDS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VREF(dc) and the first crossing of VIH(ac)min. Setup (tDS) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VREF(dc) and the first crossing of VIL(ac)max (see Figure 5). If the actual signal is always earlier than the nominal slew rate line between shaded `VREF(dc) to ac region', use nominal slew rate for derating value. If the actual signal is later than the nominal slew rate line anywhere between shaded `VREF(dc) to ac region', the slew rate of a tangent line to the actual signal from the ac level to dc level is used for derating value (see Figure 7). Hold (tDH) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VIL(dc)max and the first crossing of VREF(dc). Hold (tDH) nominal slew rate for a falling signal is defined as the slew rate between the last crossing of VIH(dc)min and the first crossing of VREF(dc) (see Figure 6). If the actual signal is always later than the nominal slew rate line between shaded `dc level to VREF(dc) region', use nominal slew rate for derating value. If the actual signal is earlier than the nominal slew rate line anywhere between shaded `dc to VREF(dc) region', the slew rate of a tangent line to the actual signal from the dc level to VREF(dc) level is used for derating value (see figure 7). For a valid transition the input signal has to remain above/below VIH/IL(ac) for some time tVAC (see Table 7). Although for slow slew rates the total setup time might be negative (i.e. a valid input signal will not have reached VIH/IL(ac) at the time of the rising clock transition) a valid input signal is still required to complete the transition and reach VIH/IL(ac). For slew rates in between the values listed in the tables the derating values may obtained by linear interpolation. These values are typically not subject to production test.
