The double data rate architecture is an 8n-prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. A single read or write operation for the DDR3 SDRAM effectively consists of a single 8n-bit-wide, four-clockcycle data transfer at the internal DRAM core and eight corresponding n-bit-wide, onehalf-clock-cycle data transfers at the I/O pins. The differential data strobe (DQS, DQS#) is transmitted externally, along with data, for use in data capture at the DDR3 SDRAM input receiver. DQS is center-aligned with data for WRITEs. The read data is transmitted by the DDR3 SDRAM and edge-aligned to the data strobes. The DDR3 SDRAM operates from a differential clock (CK and CK#). The crossing of CK going HIGH and CK# going LOW is referred to as the positive edge of CK. Control, command, and address signals are registered at every positive edge of CK. Input data is registered on the first rising edge of DQS after the WRITE preamble, and output data is referenced on the first rising edge of DQS after the READ preamble. Read and write accesses to the DDR3 SDRAM are burst-oriented. Accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of an ACTIVATE command, which is then followed by a READ or WRITE command. The address bits registered coincident with the ACTIVATE command are used to select the bank and row to be accessed. The address bits registered coincident with the READ or WRITE commands are used to select the bank and the starting column location for the burst access. The device uses a READ and WRITE BL8 and BC4. An auto precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst access. As with standard DDR SDRAM, the pipelined, multibank architecture of DDR3 SDRAM allows for concurrent operation, thereby providing high bandwidth by hiding row precharge and activation time. A self refresh mode is provided, along with a power-saving, power-down mode. Industrial Temperature The industrial temperature (IT) device requires that the case temperature not exceed –40°C or 95°C. JEDEC specifications require the refresh rate to double when T C exceeds 85°C; this also requires use of the high-temperature self refresh option. Additionally, ODT resistance and the input/output impedance must be derated when T C is < 0°C or >85°C. Automotive Temperature The automotive temperature (AT) device requires that the case temperature not exceed –40°C or 105°C. JEDEC specifications require the refresh rate to double when T C exceeds 85°C; this also requires use of the high-temperature self refresh option. Additionally, ODT resistance and the input/output impedance must be derated when T C is < 0°C or >85°C. CCMTD-1725822587-10208 automotive_4gb_ddr3l_v00h.pdf - Rev.

All rights reserved. 4Gb: x8, x16 Automotive DDR3L SDRAM Functional Description Ultra-high Temperature The Ultra-high temperature (UT) device requires that the case temperature not exceed –40°C or 125°C. JEDEC specifications require the refresh rate to double when T C exceeds 85°C; this also requires use of the high-temperature auto refresh option. When Tc > +105C, the refresh rate must be increased to 8X. Self-refresh mode is not available for Tc >+105°C. Additionally, ODT resistance and the input/output impedance must be derated when T C is < 0°C or >85°C. General Notes • The functionality and the timing specifications discussed in this data sheet are for the DLL enable mode of operation (normal operation). • Throughout this data sheet, various figures and text refer to DQs as “DQ.” DQ is to be interpreted as any and all DQ collectively, unless specifically stated otherwise. • The terms “DQS” and “CK” found throughout this data sheet are to be interpreted as DQS, DQS# and CK, CK# respectively, unless specifically stated otherwise. • Complete functionality may be described throughout the document; any page or diagram may have been simplified to convey a topic and may not be inclusive of all requirements. • Any specific requirement takes precedence over a general statement. • Any functionality not specifically stated is considered undefined, illegal, and not supported, and can result in unknown operation. • Row addressing is denoted as A[n:0]. For example, 1Gb: n = 12 (x16); 1Gb: n = 13 (x4, x8); 2Gb: n = 13 (x16) and 2Gb: n = 14 (x4, x8); 4Gb: n = 14 (x16); and 4Gb: n = 15 (x4, x8). • Dynamic ODT has a special use case: when DDR3 devices are architected for use in a single rank memory array, the ODT ball can be wired HIGH rather than routed. Refer to the Dynamic ODT Special Use Case section. • A x16 device's DQ bus is comprised of two bytes. If only one of the bytes needs to be used, use the lower byte for data transfers and terminate the upper byte as noted: – – – – Connect UDQS to ground via 1kΩ* resistor. Connect UDQS# to V DD via 1kΩ* resistor. Connect UDM to V DD via 1kΩ* resistor. Connect DQ[15:8] individually to either V SS, V DD, or V REF via 1kΩ resistors,* or float DQ[15:8]. *If ODT is used, 1kΩ resistor should be changed to 4x that of the selected ODT.

A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one bank (A10 LOW, bank selected by BA[2:0]) or all banks (A10 HIGH). The address inputs also provide the op-code during a LOAD MODE command. Address inputs are referenced to VREFCA. A12/BC#: When enabled in the mode register (MR), A12 is sampled during READ and WRITE commands to determine whether burst chop (on-the-fly) will be performed (HIGH = BL8 or no burst chop, LOW = BC4). See Table 67 (page 100). BA[2:0] Input Bank address inputs: BA[2:0] define the bank to which an ACTIVATE, READ, WRITE, or PRECHARGE command is being applied. BA[2:0] define which mode register (MR0, MR1, MR2, or MR3) is loaded during the LOAD MODE command. BA[2:0] are referenced to VREFCA. CK, CK# Input Clock: CK and CK# are differential clock inputs. All control and address input signals are sampled on the crossing of the positive edge of CK and the negative edge of CK#. Output data strobe (DQS, DQS#) is referenced to the crossings of CK and CK#. CKE Input Clock enable: CKE enables (registered HIGH) and disables (registered LOW) internal circuitry and clocks on the DRAM. The specific circuitry that is enabled/ disabled is dependent upon the DDR3 SDRAM configuration and operating mode. Taking CKE LOW provides PRECHARGE POWER-DOWN and SELF REFRESH operations (all banks idle), or active power-down (row active in any bank). CKE is synchronous for power-down entry and exit and for self refresh entry. CKE is asynchronous for self refresh exit. Input buffers (excluding CK, CK#, CKE, RESET#, and ODT) are disabled during POWER-DOWN. Input buffers (excluding CKE and RESET#) are disabled during SELF REFRESH. CKE is referenced to VREFCA. CS# Input Chip select: CS# enables (registered LOW) and disables (registered HIGH) the command decoder. 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. CS# is referenced to VREFCA. DM Input Input data mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH along with the input data during a write access. Although the DM ball is input-only, the DM loading is designed to match that of the DQ and DQS balls. DM is referenced to VREFDQ. DM has an optional use as TDQS on the x8. ODT Input On-die termination: ODT enables (registered HIGH) and disables (registered LOW) termination resistance internal to the DDR3 SDRAM. When enabled in normal operation, ODT is only applied to each of the following balls: DQ[7:0], DQS, DQS#, and DM for the x8; DQ[3:0], DQS, DQS#, and DM for the x4. The ODT input is ignored if disabled via the LOAD MODE command. ODT is referenced to VREFCA. RAS#, CAS#, WE# Input Command inputs: RAS#, CAS#, and WE# (along with CS#) define the command being entered and are referenced to VREFCA. RESET# Input Reset: RESET# is an active LOW CMOS input referenced to VSS. The RESET# input receiver is a CMOS input defined as a rail-to-rail signal with DC HIGH ≥ 0.8 × VDD and DC LOW ≤ 0.2 × VDDQ. RESET# assertion and desertion are asynchronous. CCMTD-1725822587-10208 automotive_4gb_ddr3l_v00h.pdf - Rev.
