This device is a 64 MBit dynamic RAM organized 4 194 304 by 16 bits. The device is fabric ated on
an advanced second generation 64Mbit 0,35µm-CMOS silicon gate process technology. The circuit
and process design allow this device to achieve high performanc e and low power dissipation. This
DRAM operates with a single 3.3 +/-0.3V power supply and interfaces with either LVTTL or
LVCMOS levels. Multiplexed address input s permit the HYB 3164(5)160AT to be packaged in a 400
mil wide TSOP-50 package. These packages provide high s ystem bit densities and are compatible
with co mmonly u sed automatic testing and insertion equipment. The HYB3164(5/6)160ATL parts
(L-version) have a very low power „sleep mode“ supported by Self Refresh.
