It is internally configured as an eight bank DRAM. The 4Gb chip is organized as 32Mbit x 16 I/Os x 8 bank devices. These synchronous devices achieve high speed double-data-rate transfer rates of up to 1600 Mb/sec/pin for general applications. The chip is designed to comply with all key DDR3L DRAM key features and all of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CK rising and CK# falling). All I/Os are synchronized with differential DQS pair in a source synchronous fashion. These devices operate with a single 1.35V -0.067V /+0.1V power supply and are available in FBGA packages. Table 1.

Ball Detail Symbol Type Description CK, CK# Input Differential Clock: CK and CK# are driven by the system clock. All SDRAM input signals are sampled on the crossing of positive edge of CK and negative edge of CK#. Output (Read) data is referenced to the crossings of CK and CK# (both directions of crossing). CKE Input Clock Enable: CKE activates (HIGH) and deactivates (LOW) the CK signal. If CKE goes LOW synchronously with clock, the internal clock is suspended from the next clock cycle and the state of output and burst address is frozen as long as the CKE remains LOW. When all banks are in the idle state, deactivating the clock controls the entry to the Power Down and Self Refresh modes. BA0-BA2 Input Bank Address: BA0-BA2 define to which bank the BankActivate, Read, Write, or Bank Precharge command is being applied. A0-A14 Input Address Inputs: A0-A14 are sampled during the BankActivate command (row address A0A14) and Read/Write command (column address A0-A9 with A10 defining Auto Precharge). 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). 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). CS# Input Chip Select: CS# enables (sampled LOW) and disables (sampled HIGH) the command decoder. All commands are masked when CS# is sampled HIGH. It is considered part of the command code. RAS# Input Row Address Strobe: The RAS# signal defines the operation commands in conjunction with the CAS# and WE# signals and is latched at the crossing of positive edges of CK and negative edge of CK#. When RAS# and CS# are asserted "LOW" and CAS# is asserted "HIGH" either the BankActivate command or the Precharge command is selected by the WE# signal. When the WE# is asserted "HIGH" the BankActivate command is selected and the bank designated by BA is turned on to the active state. When the WE# is asserted "LOW" the Precharge command is selected and the bank designated by BA is switched to the idle state after the precharge operation. CAS# Input Column Address Strobe: The CAS# signal defines the operation commands in conjunction with the RAS# and WE# signals and is latched at the crossing of positive edges of CK and negative edge of CK#. When RAS# is held "HIGH" and CS# is asserted "LOW" the column access is started by asserting CAS# "LOW". Then, the Read or Write command is selected by asserting WE# “HIGH" or “LOW". WE# Input Write Enable: The WE# signal defines the operation commands in conjunction with the RAS# and CAS# signals and is latched at the crossing of positive edges of CK and negative edge of CK#. The WE# input is used to select the BankActivate or Precharge command and Read or Write command. LDQS, LDQS# UDQS UDQS# LDM, UDM Confidential Input / Bidirectional Data Strobe: Specifies timing for Input and Output data. Read Data Strobe is edge triggered. Write Data Strobe provides a setup and hold time for data and DQM. LDQS Output is for DQ0~7, UDQS is for DQ8~15. The data strobes LDOS and UDQS are paired with LDQS# and UDQS# to provide differential pair signaling to the system during both reads and writes. Input Data Input Mask: Input data is masked when DM is sampled HIGH during a write cycle. LDM masks DQ0-DQ7, UDM masks DQ8-DQ15. -6／83- Rev. 1.0 May 2016 AS4C256M16D3LA-12BAN DQ0 - DQ15 Input / Data I/O: The data bus input and output data are synchronized with positive and negative Output edges of DQS/DQS#. The I/Os are byte-maskable during Writes. ODT Input On Die Termination: ODT (registered HIGH) enables termination resistance internal to the DDR3L SDRAM. When enabled, ODT is applied to each DQ, DQS, DQS#. The ODT pin will be ignored if Mode-registers, MR1and MR2, are programmed to disable RTT. RESET# 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 VDD Supply Power Supply: +1.35V -0.067V/+0.1V. VSS Supply Ground VDDQ Supply DQ Power: +1.35V -0.067V/+0.1V.

The DDR3L SDRAM uses an 8n prefetch architecture to achieve high speed operation. The 8n Prefetch architecture is combined 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 DDR3L SDRAM consists of a single 8n-bit wide, four clock data transfer at the internal DRAM core and two corresponding n-bit wide, one-half clock cycle data transfers at the I/O pins. Read and write operation to the DDR3L SDRAM are burst oriented, start at a selected location, and continue for a burst length of eight or a „chopped‟ burst of four in a programmed sequence. Operation begins with the registration of an Active command, which is then followed by a Read or Write command. The address bits registered coincident with the Active command are used to select the bank and row to be activated (BA0-BA2 select the bank; A0-A14 select the row). The address bit registered coincident with the Read or Write command are used to select the starting column location for the burst operation, determine if the auto precharge command is to be issued (via A10), and select BC4 or BL8 mode „on the fly‟ (via A12) if enabled in the mode register. Prior to normal operation, the DDR3L SDRAM must be powered up and initialized in a predefined manner. The following sections provide detailed information covering device reset and initialization, register definition, command descriptions and device operation. Figure 4.
