Rev. 0.1 / Nov. 2009 1 Revision History Revision No. 0.1 History Initial Release Draft Date Nov. 2009 Remark Preliminary Rev. 0.1 / Nov. 2009 2 Description The H5TC2G43AFR-xxA, H5TC2G83AFR-xxA are a 2Gb low power Double Data Rate III (DDR3L) Synchronous DRAM, ideally suited for the main memory applications which requires large memory density, high bandwidth and low power operation at 1.35V. Hynix DDR3L SDRAM provides backward compatibility with the 1.5V DDR3 based environment without any changes. (Please refer to the SPD information for details.) Hynix 2Gb DDR3L 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 clock (falling edges of the clock), 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.

All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK. 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 Self-Refresh 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 powerdown. Input buffers, excluding CKE, are disabled during Self-Refresh. 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. 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. Command Inputs: RAS, CAS and WE (along with CS) define the command being entered. 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. 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. 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. 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. 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. 7 CKE, (CKE0), (CKE1) Input CS, (CS0), (CS1), (CS2), (CS3) Input ODT, (ODT0), (ODT1) Input RAS. CAS.

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. Data Input/ Output: Bi-directional data bus. Data Strobe: output with read data, input with write data. Edge-aligned with read data, centered in write data. 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. 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/x16 DRAMs must disable the TDQS function via mode register A11 = 0 in MR1. No Connect: No internal electrical connection is present.

Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard. 3. VDD and VDDQ must be within 300mV of each other at all times; and VREF must not be greater than 0.6XVDDQ,When VDD and VDDQ are less than 500mV; VREF may be equal to or less than 300mV. DRAM Component Operating Temperature Range Temperature Range Symbol TOPER Notes: 1. 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 µs. It is also possible to specify a component with 1X refresh (tREFI to 7.8µs) in the Extended Temperature Range.

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).

Figure 1. shows the setup and test load for IDD and IDDQ measurements. • IDD currents (such as IDD0, IDD1, IDD2N, IDD2NT, IDD2P0, IDD2P1, IDD2Q, IDD3N, IDD3P, IDD4R, IDD4W, IDD5B, IDD6, IDD6ET, IDD6TC and IDD7) are measured as time-averaged currents with all VDD balls of the DDR3 SDRAM under test tied together. Any IDDQ current is not included in IDD currents. IDDQ currents (such as IDDQ2NT and IDDQ4R) are measured as time-averaged currents with all VDDQ balls of the DDR3 SDRAM under test tied together. Any IDD current is not included in IDDQ currents. Attention: IDDQ values cannot be directly used to calculate IO power of the DDR3 SDRAM. They can be used to support correlation of simulated IO power to actual IO power as outlined in Figure 2. In DRAM module application, IDDQ cannot be measured separately since VDD and VDDQ are using one merged-power layer in Module PCB. • For IDD and IDDQ measurements, the following definitions apply: • • • • • • • ”0” and “LOW” is defined as VIN = VIHAC(max). “MID_LEVEL” is defined as inputs are VREF = VDD/2. Timing used for IDD and IDDQ Measurement-Loop Patterns are provided in Table 1. Basic IDD and IDDQ Measurement Conditions are described in Table 2. Detailed IDD and IDDQ Measurement-Loop Patterns are described in Table 3 through Table 10. IDD Measurements are done after properly initializing the DDR3 SDRAM. This includes but is not limited to setting RON = RZQ/7 (34 Ohm in MR1); Qoff = 0B (Output Buffer enabled in MR1); RTT_Nom = RZQ/6 (40 Ohm in MR1); RTT_Wr = RZQ/2 (120 Ohm in MR2); TDQS Feature disabled in MR1 Attention: The IDD and IDDQ Measurement-Loop Patterns need to be executed at least one time before actual IDD or IDDQ measurement is started.
