GENERAL DESCRIPTION The 16Mb SDRAM is a high-speed CMOS, dynamic random-access memory containing 16,777,216 bits. It is internally configured as a dual 512K x 16 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Each of the 512K x 16-bit banks is organized as 2,048 rows by 256 columns by 16 bits. FEATURES • PC100 functionality • 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 1 Meg x 16 - 512K x 16 x 2 banks architecture with 11 row, 8 column addresses per bank • Programmable burst lengths: 1, 2, 4, 8 or full page • Auto Precharge Mode, includes CONCURRENT AUTO PRECHARGE • Self Refresh and Adaptable Auto Refresh Modes - 32ms, 2,048-cycle refresh or - 64ms, 2,048-cycle refresh or - 64ms, 4,096-cycle refresh • LVTTL-compatible inputs and outputs • Single +3.3V ±0.3V power supply • Supports CAS latency of 1, 2 and 3 • Industrial temperature range: -40°C to +85°C
