STC62WV51216
Very Low Power/Voltage CMOS SRAM
512K X 16 bit
(Single CE Pin)
The
STC62WV51216 is a high performance, very low power CMOS Static
Random Access Memory organized as 524,288 words by 16 bits and
operates from a wide range of 2.4V to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current
of 1.5uA at 3V/25oC and maximum access time of 55ns at 3.0V/85oC.
Easy memory expansion is provided by an active LOW chip enable (CE)
,active LOW output enable(OE) and three-state output drivers.
The
STC62WV51216 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The
STC62WV51216 is available in 48B BGA and 44L TSOP2 packages.
