CMOS standby current Vcc = 5.0V C-grade: 68m A (@55ns) operating current I -grade: 70m A (@55ns) operating current C-grade: 58m A (@70ns) operating current I -grade: 60m A (@70ns) operating current 2.0u A (Typ.) CMOS standby current - High speed access time : -55 55ns -70 70ns - Automatic power down when chip is deselected - Fully static operation - Data retention supply voltage as low as 1.5V - Easy expansion with CE and OE options - Three state outputs and TTL patible - DESCRIPTION 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 0.45u A at 3.0V/25o C and maximum access time of 55ns at 3.0V/85o C. 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. - PRODUCT FAMILY PRODUCT FAMILY STC62WV5128TC STC62WV5128STC STC62WV5128SC STC62WV5128EC STC62WV5128PC STC62WV5128TI STC62WV5128STI STC62WV5128SI STC62WV5128EI STC62WV5128PI OPERATING TEMPERATURE Vcc RANGE SPEED ( ns ) 55ns :3.0~5.5V 70ns :2.7~5.5V POWER DISSIPATION ( I CCSB1 , Max ) STANDBY Vcc =5.0V Operating ( I CC , Max ) Vcc = 3.0V Vcc = 3.0V 70ns Vcc...
