EM42BM1684RTA

512Mb (8M×4Bank×16)

Double DATA RATE SDRAM

Features

Description

• Internal Double-Date-Rate architecture with 2

Accesses per clock cycle.

The EM42BM1684RTA is high speed Synchronous

graphic RAM fabricated with ultra high performance

CMOS process containing 536,870,912 bits which

organized as 8Meg words x 4 banks by 16 bits.

The 512Mb DDR SDRAM uses a double data rate

architecture to accomplish high-speed operation.

The data path internally prefetches multiple bits and

It transfers the datafor both rising and falling edges

of the system clock.It means the doubled data

bandwidth can be achieved at the I/O pins.

• Single 2.5V 0.2V Power Supply

• 2.5V SSTL-2 compatible I/O

• Burst Length (B/L) of 2, 4, 8

• 2,2.5,3 Clock read latency

• Bi-directional,intermittent data strobe(DQS)

• All inputs except data and DM are sampled

at the positive edge of the system clock.

• 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

Available packages:TSOPII 66P 400mil.

• Auto Refresh and Self Refresh

• 8,192 Refresh Cycles / 64ms
