HYB3164(5)400AJ/AT(L)-40/-50/-60
16M x 4-DRAM
This device is a 64 MBit dynamic RAM organized 16 777 216 by 4 bits. The device is fabricated on
an advanced second generation 64Mbit 0,35
μ
m-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)400AJ/AT to be packaged in a
400mil wide SOJ-32 or TSOP-32 plastic package. These packages provide high system bit
densities and are compatible with commonly used automatic testing and insertion equipment. The
HYB3164(5)400ATL parts (L-versions) have a very low power sleep mode“ supported by Self
Refresh
