HYB3164(5/6)165AT(L)-40/-50/-60
4M x 16 EDO-DRAM
This device is a 64 MBit dynamic RAM organized 4 194 304 x 16 bits. The device is fabricated on
an advanced first generation 64Mbit 0,35 µm CMOS silicon gate process technology. The circuit
and process design allow this device to achieve high performance and low power dissipation. The
HYB3164(5)165AT operates with a single 3.3 +/-0.3V power supply and interfaces with either
LVTTL or LVCMOS levels. Multiplexed address inputs permit the HYB3164(5/6)165AT to be
packaged in 400mil wide TSOPII-50 package. These packages provide high system bit densities
and are compatible with commonly used automatic testing and insertion equipment. The
HYB3164(5/6)165ATL parts have a very low power „sleep mode“ supported by Self Refresh.
