SDRAM MODULE Features: • Intel PC-100/PC-66 Compliant • 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. • Quad internal banks for hiding row access/precharge. • 64ms 4096 cycle refresh. • All inputs, outputs, clocks LVTTL compatible. Options: Part Number: 16 - 8Mx8 SDRAM TSOP P8M6416YL-XX KEY DIMM MODULE TIMING PARAMETERS Module Component Clock CAS Marking Marking Frequency Latency -100CL3 -8A 100MHz 3 -66CL3 -10 66MHz 3 -66CL2 -10/12 66MHz 2 GENERAL DESCRIPTION The P8M6416YL is a high performance dynamic random-access 64MB module. This module is organized in a x64 configuration, and utilizes quad 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. _______________________________________________ ABSOLUTE MAXIMUM RATINGS: Voltage on Vcc Supply relative to Vss.............. -1 to +4.6V Operating Temperature TA (Ambient) ......... 25 ° to +70 °C Storage Temperature .................................... -55 to +125 ° Power Dissipation…………………………………………8 W Short Circuit Output Current…………………………..50 mA Stresses beyond these may cause permanent damage to the device. This is a stress rating only and functional operation of the device at or beyond these conditions is not implied. Exposure to these conditions for extended periods may affect reliability.
