HMD8M32F4E
32Mbyte(8Mx32) FP Mode 4K Ref. 100Pin SMM, 5V Design
Part No. HMD8M32F4
GENERAL DESCRIPTION
The HMD8M32F4 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.
