HMD16M64D16EV
128Mbyte(16Mx64) EDO Mode 4K/8K Ref. 3.3V, DIMM 168 pin
Part No. HMD16M64D16EV
GENERAL DESCRIPTION
The HMD16M64D16EV is a 16Mx64bits Dynamic RAM high density memory module. The HMD16M64D16EV consists
of sixteen CMOS 16Mx4bits DRAMs in TSOPІІ 400mil packages mounted on a 168-pin glass-epoxy substrate. A 0.1 or
0.22uF decoupling capacitor is mounted on the printed circuit board for each DRAM. The HMD16M64D16EV is a Dual In-
line Memory Module and is intended for mounting into 168 pin edge connector sockets
