HMD8M32M16EG

HANBit HMD8M32M16EG 32Mbyte(8Mx32) 72-pin EDO MODE 2K Ref. SIMM Design 5V Part No. HMD8M32M16EG GENERAL DESCRIPTION The HMD8M32M16EG is a 8M x 32bit dynamic RAM high density memory module. The module consists of sixteen CMOS 4M x 4bit DRAMs in 24-pin SOJ packages mounted on a 72-pin, double-sided, FR-4-printed circuit board. 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 and all inputs and outputs are TTL-compatible.
