128Mbyte (32Mx32) 72-pin EDO Mode 4K Ref. SIMM Design 5V
Part No. HMD32M32M16EG
GENERAL DESCRIPTION
The HMD32M32M16EG is a 16M x 32bit dynamic RAM high-density memory module. The module consists of sixteen
CMOS 16M x 4bit DRAMs in 32-pin TSOPII packages mounted on a 72-pin, double-sided, FR-4-printed circuit board. A
0.1uF 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.
