HMD4M32M2VE  
16Mbyte(4Mx32) DRAM SIMM EDO MODE, 4K Refresh, 3.3V  
Part No. HMD4M32M2VE, HMD4M32M2VEG  
GENERAL DESCRIPTION  
The HMD4M32M2VE is a 4M x 32 bit dynamic RAM high-density memory module. The module consists of two CMOS  
4M x 16 bit DRAMs in 50-pin TSOP packages mounted on a 72-pin. A 0.1 or 0.22uF decoupling capacitor is mounted on  
the printed circuit board for each DRAM components. The module is a single In-line memory module with edge  
connections and is intended for mounting in to 72-pin edge connector sockets. All module components may be powered  
from a single 3.3V DC power supply. All inputs and outputs are LVTTL-compatible.
