⢠Operating case temperature range
â TC = 0°C to +95°C
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
â Synchronous ODT
â Dynamic ODT
â Asynchronous ODT
⢠Multi Purpose Register (MPR) for pre-defined pattern
read out
⢠ZQ calibration for DQ drive and ODT
⢠/RESET pin for Power-up sequence and reset function
⢠SRT range:
â Normal/extended
⢠Programmable Output driver impedance control
⢠Seamless BL4 access with bank-grouping
â Applied only for DDR3-1333 and 1600
