Very Low Power/Voltage CMOS SRAM
512K x 16 or 1M x 8 bit switchable
BS616LV8023
FEATURES
DESCRIPTION
• Very low operation voltage : 2.4 ~ 3.6V
• 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
• High speed access time :
-70 70ns (Max.) at Vcc= 3.0V
-10 100ns (Max.) at Vcc= 3.0V
• 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 CE1, CE2 and OE options
• I/O Configuration x8/x16 selectable by CIO, LB and UB pin
The BS616LV8023 is a high performance, very low power CMOS Static
Random Access Memory organized as 524,288 words by 16 bits or
1,048,576 bytes by 8 bits selectable by CIO pin and operates from a wide
range of 2.4V 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 0.5uA and maximum access time of 70/100ns in 3.0V operation.
Easy memory expansion is provided by an active HIGH chip
enable2(CE2), active LOW chip enable1(CE1), active LOW output
enable(OE) and three-state output drivers.
The BS616LV8023 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The BS616LV8023 is available in 48-pin BGA type.

These 19 address inputs select one of the 524,288 x 16-bit words in the RAM.
This address input incorporate with the above 19 address inputs select one of the
1,048,576 x 8-bit bytes in the RAM if the CIO is LOW. Don't use when CIO is HIGH.
This input selects the organization of the SRAM. 524,288 x 16-bit words configuration
is selected if CIO is HIGH. 1,048,576 x 8-bit bytes configuration is selected if CIO is
LOW.
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. The chip is deselected when
both LB and UB pins are HIGH.
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 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. T
WR 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 or LB,UB 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
7. D
OUT is the same phase of write data of this write cycle.
8. D
OUT 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.
CW is measured from the later of CE2 going high or CE1 going low to the end of write.
