DDR3L SDRAM
MT41K1G4 – 128 Meg x 4 x 8 banks MT41K512M8 – 64 Meg x 8 x 8 banks MT41K256M16 – 32 Meg x 16 x 8 banks
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
• 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 105°C
– 64ms, 8192-cycle refresh up to 85°C – 32ms, 8192-cycle refresh at >85°C to 95°C – 16ms, 8192-cycle refresh at >95°C to 105°C
• Self refresh temperature (SRT) • Automatic self refresh (ASR) • Write leveling • Multipurpose register • Output driver calibration
Options
• Configuration – 1 Gig x 4 – 512 Meg x 8 – 256 Meg x 16
• FBGA package (Pb-free) – x4, x8 – 78-ball (9mm x 10.5mm) Rev. E – 78-ball (7.5mm x 10.6mm) Rev. N – 78-ball (8mm x 10.5mm) Rev. P
• FBGA package (Pb-free) – x16 – 96-ball (9mm x 14mm) Rev. E – 96-ball (7.5mm x 13.5mm) Rev. N – 96-ball (8mm x 14mm) Rev. P
• Timing – cycle time – 938ps @ CL = 14 (DDR3-2133) – 1.07ns @ CL = 13 (DDR3-1866) – 1.25ns @ CL = 11 (DDR3-1600)
• Operating temperature – Commercial (0°C TC +95°C) – Industrial (–40°C TC +95°C) – Automotive (–40°C TC +105°C)
