May 2014 Ordering information page 1 - Commercial (Extended) (0 ~ 95C) - Industrial (-40 ~ 95C) Rev 3.0 Updated Table 12. Recommended DC Operating August 2014 Conditions page 21 Added CL=5 & CL=6 to Table 18 page 26 Confidential 1 Rev. 3.0 Aug. /2014 AS4C256M8D3 2 Gb (256M x 8 bit) DDR3 Synchronous DRAM (SDRAM) Confidential Advanced (Rev. 3.0, Aug. /2014) Overview Features JEDEC Standard Compliant The 2Gb Double-Data-Rate-3 DRAMs is double data rate architecture to achieve high-speed operation. It is Power supplies: V & V = +1.5V 0.075V DD DDQ internally configured as an eight bank DRAM. Operating temperature: The 2Gb chip is organized as 32Mbit x 8 I/Os x 8 bank - Commercial(Extended) (0 ~ 95C) devices. These synchronous devices achieve high - Industrial (-40 ~ 95C) speed double-data-rate transfer rates of up to 1600 Supports JEDEC clock jitter specification Mb/sec/pin for general applications. Fully synchronous operation The chip is designed to comply with all key DDR3 Fast clock rate: 667/800MHz DRAM key features and all of the control and address Differential Clock, CK & CK inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the Bidirectional differential data strobe cross point of differential clocks (CK rising and CK - DQS & DQS falling). All I/Os are synchronized with differential DQS 8 internal banks for concurrent operation pair in a source synchronous fashion. 8n-bit prefetch architecture These devices operate with a single 1.5V 0.075V Internal pipeline architecture power supply and are available in BGA packages.
