Product Specifications
VL470L2925-B3SG
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.
Features
• 200-pin, small-outline dual in-line memory module (SODIMM)
• Two data transfers per clock cycle
• VDD = VDDQ = 2.5V +/-0.2V for DDR333
• JEDEC standard 2.5V I/O (SSTL_2 compatible)
• VDDSPD = 2.3V to 3.6V
• Bi-directional data-strobe (DQS)
• Differential clock inputs (CK and CK#)
• DLL aligns DQ and DQS transition with CK transition
• Programmable read latency: DDR333 (2.5 clock)
• Programmable burst; length (2, 4, 8)
• Programmable burst (sequential & interleave)
• Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)
• Serial presence detect (SPD) with EEPROM
• Lead-free, RoHS compliant
• JEDEC pinout
• Gold edge contacts
• PCB: Height 31.75mm (1.250”), double sided component
• Operating temperature (TA): - Commercial (0^oC <= TA <= 70^oC)
- Industrial (-40^oC <= TA <= +85^oC)
