DESCRIPTION
The BS616LV8015 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 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 3uA and maximum access time of 55/70ns in 5V 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 BS616LV8015 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV8015 is available in 48-pin BGA package.

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.
