 DESCRIPTION

The BS616UV4010 is a high performance, Ultra low power CMOS Static Random Access Memory organized as 262,144 words by 16 bits and operates from a wide range of 1.8V to 3.6V supply voltage. Advanced CMOS technology and circuit techniques provide both high speed and low power features with a typical CMOS standby current of 0.20uA and maximum access time of 70/100ns in 2.0V operation. Easy memory expansion is provided by an active LOW chip enable(CE) and active LOW output enable(OE) and three-state output drivers. The BS616UV4010 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The BS616UV4010 is available in DICE form, JEDEC standard 44-pin TSOP Type 2 package and 48-pin BGA package.

 TRUTH TABLE

These 18 address inputs select one of the 262,144 x 16-bit words in the RAM.

CE is active LOW. Chip enables must be active when data read from or write to the

device. if 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.

NOTES:

1. WE must be high during address transitions.

2. The internal write time of the memory is defined by the overlap of CE 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. T

WR is measured from the earlier of CE 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 CE 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 = V

OUT is the same phase of write data of this write cycle.

7. D

OUT is the read data of next address.

8. D

9. If CE 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 C

The parameter is guaranteed but not 100% tested.

11. T

CW is measured from the later of CE going low to the end of write.
