BS616LV4025

BSI „ FEATURES Very Low Power/Voltage CMOS SRAM 256K x 16 or 512K x 8 bit switchable „ DESCRIPTION BS616LV4025 Operation voltage : 4.5~5.5V Low power consumption : Vcc = 5.0V C-grade: 45mA (Max.) operating current I-grade : 50mA (Max.) operating current 1.5uA (Typ.) CMOS standby current High speed access time : -70 70ns (Max.) at Vcc=5V -55 55ns (Max.) at Vcc=5V Automatic power down when chip is deselected Three state outputs and TTL compatible Fully static operation Data retention supply voltage as low as 1.5V Easy expansion with CE1, CE2 and OE options I/O Configuration x8/x16 selectable by CIO, LB and UB pin The BS616LV4025 is a high performance, very low power CMOS Static Random Access Memory organized as 262,144 words by 16 bits or 524,288 bytes by 8 bits selectable by CIO pin and operates from a wide range of 4.5V 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 and maximum access time of 70/55ns in 5V operation. Easy memory expansion is provided by an active HIGH chip enable2(CE2), and active LOW chip enable1(CE1), an active LOW output enable(OE) and three-state output drivers. The BS616LV4025 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The BS616LV4025 is available in DICE form and 48-pin BGA type. „ PRODUCT FAMILY OPERATING TEMPERATURE +0 C to +70 C -40 C to +85 C O O O ...
