It is Power supplies: V & V = +1.5V 0.075V DD DDQ internally configured as an eight bank DRAM. Operating temperature range: The 4Gb chip is organized as 32Mbit x 16 I/Os x 8 bank : T = 0~95 C - Commercial C devices. These synchronous devices achieve high speed - Industrial : T = -40~95 C C double-data-rate transfer rates of up to 1866 Mb/sec/pin Supports JEDEC clock jitter specification for general applications. Fully synchronous operation The chip is designed to comply with all key DDR3 DRAM key features and all of the control and address inputs are Fast clock rate: 800/933MHz synchronized with a pair of externally supplied differential Differential Clock, CK & CK clocks. Inputs are latched at the cross point of differential Bidirectional differential data strobe clocks (CK rising and CK falling). All I/Os are synchronized - DQS & DQS with differential DQS pair in a source synchronous fashion. 8 internal banks for concurrent operation 8n-bit prefetch architecture Pipelined internal architecture Precharge & active power down Programmable Mode & Extended Mode registers Additive Latency (AL): 0, CL-1, CL-2 Programmable Burst lengths: 4, 8 Burst type: Sequential / Interleave Output Driver Impedance Control Average refresh period - 8192 cycles/64ms (7.8us at -40C T +85C) C - 8192 cycles/32ms (3.9us at +85C T +95C) C Write Leveling ZQ Calibration Dynamic ODT (Rtt Nom & Rtt WR) RoHS compliant 96-ball 7.5 x 13.5 x 1.2mm FBGA package Auto Refresh and Self Refresh - Pb and Halogen Free Table 1.
