PART NO.:
VL470L2925-R3SG
REV: 1.0
General Information
1GB 128Mx64 DDR SDRAM NON-ECC UNBUFFERED SODIMM 200-PIN
Description
The VL470L2925 is a 128Mx64 Double Data Rate SDRAM high density SODIMM. This dual rank memory module
consists of sixteen CMOS 64Mx8 bits with 4 banks 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
DDR SDRAM.
