2 / 22 page EM42CM1684RTA Jan. 2012 www.eorex.com 2/22 1Gb (16M ×4Bank×16) Double DATA RATE SDRAM Features • Internal Double-Date-Rate architecture with twice accesses per clock cycle. • Single 2.5V ±0.2V Power Supply • 2.5V SSTL-2 compatible I/O • Burst Length (B/L) of 2, 4, 8 • CAS Latency: 3 • Bi-directional data strobe (DQS) for input and output data, active by both edges • Data Mask (DM) for write data • Sequential & Interleaved Burst type available • Auto precharge option for each burst accesses • DQS edge-aligned with data for Read cycles • DQS center-aligned with data for Write cycles • DLL aligns DQ & DQS transitions with CLK transition • Auto Refresh and Self Refresh • 8,192 Refresh Cycles / 64ms Description The EM42CM1684RTA is high speed Synchronous graphic RAM fabricated with ultra high performance CMOS process containing 1,073,741,824 bits which organized as 16Meg words x 4 banks by 16 bits. The 1Gb DDR SDRAM uses double data rate architecture to accomplish high-speed operation. The data path internally prefetches multiple bits and transfers the data for both rising and falling edges of the system clock. It means the doubled data bandwidth can be achieved at the I/O pins.
