VL470T5664A-E6S/D5S/CCS
General Information
2GB 256Mx64 DDR2 SDRAM NON-ECC UNBUFFERED SODIMM 200-PIN
Description:
The VL470T5664A is a 256M X 64 DDR2 SDRAM high density SODIMM. This memory module consists of
sixteen CMOS 128M X 8 bit (2 x 128Mx8 configured to 128M x16) with 8 banks DDR2 Synchronous DRAMs in
BGA packages and a 2K EEPROM in 8-pin TSSOP package. This module is a 200-pin small-outline dual
in-line memory module and is intended for mounting into a connector socket. Decoupling capacitors are
mounted on the printed circuit board for each DDR2 SDRAM.

Supply voltage
Notes: 1. VDD, VDDQ must track each other. VDDQ must be less than or equal to VDD.
2. VREF is expected to equal VDDQ/2 of the transmitting device and to track variations in the DC level of the same. Peak-topeak noise on VREF may not exceed +/-1 percent of the DC value. Peak-to-peak AC noise on VREF may not exceed +/-2
percent of VREF. This measurement is to be taken at the nearest VREF bypass capacitor.
3. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal
to VREF and must track variations in the DC level of VREF.
4. VDDQ tracks with VDD; VDDL tracks with VDD.
