DESCRIPTION
The BS616UV4020 is a high performance, ultra 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 1.8V to 3.6V supply voltage.

FEATURES
• Ultra low operation voltage : 1.8 ~ 3.6V
• Ultra low power consumption :
    Vcc = 2.0V C-grade: 15mA (Max.) operating current
                        I-grade : 20mA (Max.) operating current
                        0.2uA (Typ.) CMOS standby current
    Vcc = 3.0V C-grade: 20mA (Max.) operating current
                        I-grade : 25mA (Max.) operating current
                        0.25uA (Typ.) CMOS standby current
• High speed access time :
    -70 70ns (Max.) at Vcc=2.0V
    -10 100ns (Max.) at Vcc=2.0V
• 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
