Description
DDR3L SDRAM (1.35V) is a low voltage version of the DDR3 (1.5V) SDRAM. Refer to the DDR3 (1.5V) SDRAM data sheet specifications when running in 1.5V compatible mode.
Features
• VDD = VDDQ = 1.35V (1.283–1.45V)
• Backward compatible to VDD = VDDQ = 1.5V ±0.075V
– Supports DDR3L devices to be backward com
patible in 1.5V applications
• Differential bidirectional data strobe
• 8n-bit prefetch architecture
• Differential clock inputs (CK, CK#)
• 8 internal banks
• Nominal and dynamic on-die termination (ODT)
for data, strobe, and mask signals
• Programmable CAS (READ) latency (CL)
• Programmable posted CAS additive latency (AL)
• Programmable CAS (WRITE) latency (CWL)
• Fixed burst length (BL) of 8 and burst chop (BC) of 4
(via the mode register set [MRS])
• Selectable BC4 or BL8 on-the-fly (OTF)
• Self refresh mode
• TC of 0°C to +95°C
– 64ms, 8192-cycle refresh at 0°C to +85°C
– 32ms at +85°C to +95°C
• Self refresh temperature (SRT)
• Automatic self refresh (ASR)
• Write leveling
• Multipurpose register
• Output driver calibration
