HYB3164(5)805BJ/BT(L)-40/-50/-60
8M x 8-DRAM
This HYB3164(5)805B is a 64 MBit dynamic RAM organized 8 388 608 by 8 bits. The device is
fabricated in SIEMENS’most advanced 0,25 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)805B 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)400B 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)805BTL parts have a very low power „sleep mode“supported by Self Refresh.
