HYB3164(5/6)160AT(L)-40/-50/-60
4M x 16-DRAM
This device is a 64 MBit dynamic RAM organized 4 194 304 by 16 bits. The device is fabricated on
an advanced second generation 64Mbit 0,35µm-CMOS silicon gate process technology. The circuit
and process design allow this device to achieve high performance 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 inputs permit the HYB 3164(5)160AT to be packaged in a 400
mil wide TSOP-50 package. These packages provide high system bit densities and are compatible
with commonly used automatic testing and insertion equipment. The HYB3164(5/6)160ATL parts
(L-version) have a very low power „sleep mode“ supported by Self Refresh.
