FEATURES
Very Low Power/Voltage CMOS SRAM 512K X 16 bit
DESCRIPTION
BS616LV8012
* Very low operation voltage : 2.4~5.5V * Very low power consumption : Vcc = 3.0V C-grade: 20mA (Max.) operating current I-grade : 25mA (Max.) operating current 0.5uA (Typ.) CMOS standby current Vcc = 5.0V C-grade: 45mA (Max.) operating current I-grade : 50mA (Max.) operating current 3uA (Typ.) CMOS standby current * High speed access time : -70 70ns (Max.) at Vcc=3V -10 100ns (Max.) at Vcc=3V * 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 CE2,CE1 and OE options * I/O Configuration x8/x16 selectable by LB and UB pin
The BS616LV8012 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 0.5uA and maximum access time of 70/100ns in 3V operation. Easy memory expansion is provided by an active LOW chip enable(CE1), active HIGH chip enable (CE2), active LOW output enable(OE) and three-state output drivers. The BS616LV8012 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The BS616LV8012 is available in 48-pin BGA package.

BS616LV8012
Function
These 19 address inputs select one of the 524,288 x 16-bit words in the RAM. CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active when data read from or write to the device. If either chip enable is not active, the device is deselected and is in a standby power mode. The DQ pins will be in the high impedance state when the device is deselected. The write enable input is active LOW and controls read and write operations. With the chip selected, when WE is HIGH and OE is LOW, output data will be present on the DQ pins; when WE is LOW, the data present on the DQ pins will be written into the selected memory location. The output enable input is active LOW. If the output enable is active while the chip is selected and the write enable is inactive, data will be present on the DQ pins and they will be enabled. The DQ pins will be in the high impedance state when OE is inactive. Lower byte and upper byte data input/output control pins. These 16 bi-directional ports are used to read data from or write data into the RAM. Power Supply Ground

NOTES: 1. WE must be high during address transitions. 2. The internal write time of the memory is defined by the overlap of CE2, CE1 and WE low. All signals must be active to initiate a write and any one signal can terminate a write by going inactive. The data input setup and hold timing should be referenced to the second transition edge of the signal that terminates the write. 3. TWR is measured from the earlier of CE2 going low, or CE1 or WE going high at the end of write cycle. 4. During this period, DQ pins are in the output state so that the input signals of opposite phase to the outputs must not be applied. 5. If the CE2 high transition or CE1 low transition occurs simultaneously with the WE low transitions or after the WE transition, output remain in a high impedance state. 6. OE is continuously low (OE = VIL ). 7. DOUT is the same phase of write data of this write cycle. 8. DOUT is the read data of next address. 9. If CE2 is high or CE1 is low during this period, DQ pins are in the output state. Then the data input signals of opposite phase to the outputs must not be applied to them. 10. Transition is measured 500mV from steady state with CL = 5pF as shown in Figure 1B. The parameter is guaranteed but not 100% tested. 11. TCW is measured from the later of CE2 going high or CE1 going low to the end of write.
