DESCRIPTIONThis document describes ValueRAM's 256M x 64-bit (2GB) DDR3L-1600 CL11 SDRAM (Synchronous DRAM) 1Rx16,memory module, based on four 256M x 16-bit FBGA components. The SPD is programmed to JEDEC standard latencyDDR3-1600 timing of 11-11-11 at 1.35V or 1.5V. This 204-pin SODIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
FEATURES• JEDEC standard 1.35V (1.28V ~ 1.45V) and 1.5V (1.425V ~1.575V) Power Supply• VDDQ = 1.35V (1.28V ~ 1.45V) and 1.5V (1.425V ~ 1.575V)• 800MHz fCK for 1600Mb/sec/pin• 8 independent internal bank• Programmable CAS Latency: 11, 10, 9, 8, 7, 6, 5• Programmable Additive Latency: 0, CL - 2, or CL - 1 clock• 8-bit pre-fetch• Burst Length: 8 (Interleave without any limit, sequential withstarting address “000” only), 4 with tCCD = 4 which does notallow seamless read or write [either on the fly using A12 orMRS]• Bi-directional Differential Data Strobe• Internal(self) calibration: Internal self-calibration through ZQpin (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• Asynchronous Reset• PCB : Height 1.180” (30.00mm), single sided Cycle Time (tRCmin)
