Advanced CMOS technology and circuit techniques provide both high speed and low power features with typical CMOS standby current of 0.8uA 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 (CE1), active HIGH chip enable (CE2) and active LOW output enable (OE) and three-state output drivers. The BS616LV8016 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The BS616LV8016 is available in DICE form and 48-ball BGA package. n POWER CONSUMPTION POWER DISSIPATION PRODUCT FAMILY BS616LV8016DC BS616LV8016FC BS616LV8016FI OPERATING TEMPERATURE Commercial +0OC to +70OC Industrial -40OC to +85OC STANDBY (ICCSB1, Max) Operating (ICC, Max) PKG TYPE VCC=3.0V 10MHz fMax.

Both chip enables must be active when data read form or write to the device. If either chip enable is not active, the device is deselected and is in 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 impendence state when OE is inactive. Lower byte and upper byte data input/output control pins. OE Output Enable Input LB and UB Data Byte Control Input DQ0-DQ15 Data Input/Output Ports VCC VSS 16 bi-directional ports are used to read data from or write data into the RAM.

WE must be high during address transitions. 2. The internal write time of the memory is defined by the overlap of CE1 and CE2 active 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 CE1 or WE going high or CE2 going low 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 CE1 low transition or the CE2 high 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 CE1 is low and CE2 is high 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. The parameter is guaranteed but not 100% tested. 11. tCW is measured from the later of CE1 going low or CE2 going high to the end of write. 12. The change of Read/Write cycle must accompany with CE or address toggled.
