P2M648YL

www.DataSheet4U.com SDRAM MODULE Features: JEDEC - Standard 168-pin (gold), dual in-line memory module (DIMM). TSOP components. Single 3.3v +.3v power supply. Nonbuffered fully synchronous; all signals measured on positive edge of system clock. Internal pipelined operation; column address can be changed every clock cycle. Dual internal banks for hiding row access/precharge. 64ms 4096 cycle refresh. All inputs, outputs, clocks LVTTL compatible. P2M648YL, P4M6416YL 2M, 4M x 64 DIMM PIN ASSIGNMENT (Front View) 168-PIN DIMM Options: 8 - 2Mx8 SDRAM TSOP 16 - 2Mx8 SDRAM TSOP KEY DIMM Module Marking -66CL2 -100CL3A Part Number: P2M648YL-XX P4M6416YL-XX MODULE TIMING PARAMETERS Component Clock CAS Latency Marking Freq -10/-12 66MHZ 2 or3 -8A 100MHZ 3 GENERAL DESCRIPTION The S2M6408YL and S4M6416YL are high performance dynamic random-access 16MB and 32MB modules respectively. These modules are organized in a x64 configuration, and utilize dual bank architecture with a synchronous interface. All signals are registered on the positive edge of the clock signals CK0 through CK3. Read and write accesses to the SDRAM are burst oriented; accesses start at a location and continue for a programmed number of locations in a sequence. Accesses begin with an ACTIVE command which is followed by a READ or WRITE command.
