32Mbyte(8Mx32) EDO Mode 4K Ref. 100Pin SMM, 5V Design
Part No. HMD8M32F4E
GENERAL DESCRIPTION
The HMD8M32F4E 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 100-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 100-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.
