GENERAL DESCRIPTION
The 512Mb SDRAM is a high-speed CMOS, dynamic random-access memory containing 536, 870, 912 bits. It is internally configured as a quad-bank DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Each of the 67,108,864-bit banks is organized as 8,192 rows by 1024 columns by 16 bits.

FEATURES
• Full Military temp (-55°C to 125°C) processing available
• Configuration: 32 Meg x 16 (8 Meg x 16 x 4 banks)
• Fully synchronous; all signals registered on positive
   edge of system clock
• Internal pipelined operation; column address can be
   changed every clock cycle
• Internal banks for hiding row access/precharge
• Programmable burst lengths: 1, 2, 4, 8 or full page
• Auto Precharge, includes CONCURRENT AUTO
   PRECHARGE and Auto Refresh Modes
• Self Refresh Mode (IT & ET)
• 64ms, 8,192-cycle refresh (IT)
• 24ms 8,192 cycle refresh (XT)
• WRITE Recovery (tWR = “2 CLK”)
• LVTTL-compatible inputs and outputs
• Single +3.3V ±0.3V power supply
