The BS62LV8001 is ahigh performance , very low power CMOS Static Random Access Memory organized as 1,048,576 wordsby 8 bits and operates from a wide range of 2.4V to 5.5V supply voltage.

Advanced CMOS technology and circuit techniques provide bothhighspeed and low power features with a typical CMOS standby current of1.5uAat 3V/25oC and maximum access time of 55ns at 3.0V/85oC.

Easy memory expansion is provided by an active LOW chip enable(CE1), an active HIGH chip enable (CE2) and active LOW output enable (OE) and three-state output drivers.

The BS62LV8001 hasanautomatic power down feature, reducing thepower consumption significantly when chip is deselected.

The BS62LV8001 is available in 48B BGA and 44L TSOP2 packages.

BS62LV8001FunctionThese 20address inputsselect one of the 1,048,576x 8-bit wordsin the RAMCE1 is active LOW and CE2 is active HIGH. Both chip enables mustbe active whendata read from or write to the device. If either chip enable is not active, the device isdeselected 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 writeoperations. With thechip selected, when WE is HIGH and OE is LOW, output data will be present on theDQ pins; when WE is LOW, the data present on the DQ pins will bewritten into theselected memory location.NameA0-A19 Address InputCE1 Chip Enable 1 InputCE2 Chip Enable 2 InputWE Write Enable InputOE Output Enable InputThe output enable input is active LOW. If the output enable is active while the chip isselected and the write enable is inactive, data will be present on the DQ pins and theywill be enabled.

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 signalsmust 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 ofthe signal that terminates the write.

3. TWRis 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 phaseto 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 WEtransition, output remain in a high impedance state.6. OE is continuously low (OE =VIL).

7.DOUTis the same phase of write data of this write cycle.8.DOUTis 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 ofopposite phase to the outputs must not be applied to them.10. The parameter is guaranteed but not 100% tested.

11.TCW is measured from the later of CE2 going high or CE1 going low tothe end of write.
