Overview
HANBit HMD4M32M2EG 16Mbyte(4Mx32) 72-pin SIMM EDO Mode, 4K Refresh, 5V Part No.
HMD4M32M2E, HMD4M32M2EG GENERAL DESCRIPTION The HMD4M32M2E 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 5V DC power supply.
All inputs and outputs are TTL-compatible.
