4Gb B-die DDR3 SDRAM

Key Features;

• JEDEC standard 1.5V(1.425V~1.575V)
• VDDQ = 1.5V(1.425V~1.575V)
• 400 MHz fCK for 800Mb/sec/pin, 533MHz fCK for 1066Mb/sec/pin, 667MHz fCK for 1333Mb/sec/pin, 800MHz fCK for 1600Mb/sec/pin, 933MHz fCK for 1866Mb/sec/pin, 1066 MHz fCK for 2133Mb/sec/pin
• 8 Banks
• Programmable CAS Latency(posted CAS): 5,6,7,8,9,10,11,12,13,14
• Programmable Additive Latency: 0, CL-2 or CL-1 clock
• Programmable CAS Write Latency (CWL) = 5 (DDR3-800), 6 (DDR3-1066), 7 (DDR3-1333) , 8 (DDR3-1600), 9 (DDR3-1866) and 10 (DDR3-2133)
• 8-bit pre-fetch

• Internal(self) calibration : Internal self calibration through ZQ pin (RZQ : 240 ohm ± 1%)
• On Die Termination using ODT pin
• Average Refresh Period 7.8us at lower than TCASE 85°C, 3.9us at 85°C < TCASE < 95 °C
• Support Industrial Temp ( -40 ∼ 85°C )
• Asynchronous Reset
• Package : 96 balls FBGA - x16
• All of Lead-Free products are compliant for RoHS
• All of products are Halogen-free
