HMD8M32M4G  
32Mbyte(8Mx32) 72-pin SIMM, FP Mode, 4K Ref. 5V  
Part No. HMD8M32M4, HMD8M32M4G  
GENERAL DESCRIPTION  
The HMD8M32M4 is a 8M x 32bit dynamic RAM high density memory module. The module consists of four CMOS 4M x  
16 bit DRAMs in 50-pin TSOP packages mounted on a 72-pin, double-sided, FR-4-printed circuit board. A 0.1uF 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 5V DC power supply and all inputs and outputs  
are TTL-compatible.
