Kingston Auto Temp DDR3L SDRAM

Kingston Auto Temp DDR3L SDRAM memory devices feature double-data-rate architecture and 8-bit prefetch pipelined design for high-speed, dual data transfers per clock cycle. These 2G/4Gbit density DDR3L SDRAMs, with 16M/32M words x 16 bits x 8 banks organization, are available in RoHS-compliant and Halogen-free 96-ball FBGA packages. These devices are designed to meet the needs of applications that require an extended automotive operating temperature range of -40°C to 105°C. Typical applications include automotive, industrial IoT / robotics, factory automation, and 5G networking/telecommunications communication modules.

Features

  • Double-data-rate architecture: two data transfers per clock cycle
  • The high-speed data transfer is realized by the 8 bits prefetch pipelined architecture
  • Bi-directional differential data strobe (DQS and /DQS) is transmitted/received with data for capturing data at the receiver
  • DQS is edge-aligned with data for READs, center-aligned with data for WRITEs
  • Differential clock inputs (CK and /CK)
  • DLL aligns DQ and DQS transitions with CK transitions
  • Commands entered on each positive CK edge; data and data mask referenced to both edges of DQS
  • Data mask (DM) for write data
  • Posted /CAS by programmable additive latency for better command and data bus efficiency
  • On-Die-Termination (ODT) for better signal quality:
    • Synchronous ODT
    • Dynamic ODT
    • Asynchronous ODT
  • Multi-Purpose Register (MPR) for pre-defined pattern read-out
  • ZQ calibration for DQ drive and ODT
  • Automatic Self-Refresh (ASR)
  • /RESET pin for Power-up sequence and reset function
  • SRT range - Normal/extended
  • Programmable Output driver impedance control
