VL-MM8-1EBN

Product Specifications PART NO.: VL470T2863A-E6S-I REV: 1.0 General Information 1GB 128Mx64 DDR2 SDRAM NON-ECC UNBUFFERED SODIMM 200-PIN Description The VL470T2863A is a 128Mx64 DDR2 SDRAM high density SODIMM. This single rank memory module consists of eight CMOS 128Mx8 bits with 8 banks DDR2 synchronous DRAMs in BGA packages and a 2K EEPROM in an 8-pin TSSOP package. This module is a 200-pin small-outline dual in-line memory module and is intended for mounting into an edge connector socket. Decoupling capacitors are mounted on the printed circuit board for each DDR2 SDRAM.
