Description

The BS62UV256 is a high performance, ultra low power CMOS Static Random Access Memory organized as 32,768 words by 8 bit and operates from a wide range of 1.8V to 3.6V supply voltage.

Advanced CMOS technology and circuit techniques of BS62UV256SC provide both h speed and low power features with a typical CMOS standby current 0.005uA and maximum access time of 150ns in 2V operation.

Easy memory expansion of BS62UV256SC is provided by an active LOW enable (CE), and active LOW output enable (OE) and three-st output drivers.

The BS62UV256 has an automatic power down feature, reducing the power consumption significantly when chip is deselected.

The BS62UV256 is available in the JEDEC standard 28 330mil Plastic SOP, 8mmx13.4mm TSOP (normal type), 300mi SOJ and 600mil Plastic DIP.
