It is internally configured as 4 Banks of 8M word x 16 Fully synchronous operation DRAM with a synchronous interface (all signals are Internal pipelined architecture registered on the positive edge of the clock signal, 8M word x 16-bit x 4-bank CLK). Read and write accesses to the SDRAM are Programmable Mode registers burst oriented accesses start at a selected location - CAS Latency: 2 or 3 and continue for a programmed number of locations - Burst Length: 1, 2, 4, 8, or full page in a programmed sequence. Accesses begin with the - Burst Type: Sequential or Interleaved registration of a Bank Activate command which is then followed by a Read or Write command. The - Burst stop function SDRAM provides for programmable Read or Write Auto Refresh and Self Refresh burst lengths of 1, 2, 4, 8, or full page, with a burst 8192 refresh cycles/64ms termination option. An auto precharge function may CKE power down mode be enabled to provide a self-timed row precharge that Single +3.3V 0.3V power supply is initiated at the end of the burst sequence. The Operating Temperature Range: refresh functions, either Auto or Self Refresh are easy to use. By having a programmable mode - Commercial: T = 0~70C A register, the system can choose the most suitable - Industrial: T = -40~85C A modes to maximize its performance. These devices Interface: LVTTL are well suited for applications requiring high memory 54-pin 400 mil plastic TSOP II package bandwidth and particularly well suited to high - Pb free and Halogen free performance PC applications.
