Description
DDR3L SDRAM (1.35V) is a low
voltage version of the DDR3 (1.5V) SDRAM. Refer to DDR3 (1.5V) SDRAM (Die Rev :E) 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 compatible in 1.5V applications
