1 / 10 page Revision 1.1 Jan. 2004 1 R0201- STC62WV5128 Very Low Power/Voltage CMOS SRAM 512K X 8 bit • Wide Vcc operation voltage : 2.4V ~ 5.5V • Very low power consumption : Vcc = 3.0V C-grade: 29mA (@55ns) operating current I -grade: 30mA (@55ns) operating current C-grade: 24mA (@70ns) operating current I -grade: 25mA (@70ns) operating current 0.45uA (Typ.) CMOS standby current Vcc = 5.0V C-grade: 68mA (@55ns) operating current I -grade: 70mA (@55ns) operating current C-grade: 58mA (@70ns) operating current I -grade: 60mA (@70ns) operating current 2.0uA (Typ.) CMOS standby current • High speed access time : -55 55ns -70 70ns • Automatic power down when chip is deselected • Fully static operation The STC62WV5128 is a high performance, very low power CMOS Static Random Access Memory organized as 524,288 words by 8 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 0.45uA at 3.0V/25oC and maximum access time of 55ns at 3.0V/85oC. Easy memory expansion is provided by an active LOW chip enable (CE) , and active LOW output enable (OE) and three-state output drivers. The STC62WV5128 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The STC62WV5128 is available in the JEDEC standard 32L SOP, TSOP , PDIP, TSOP II and STSOP package.
