High Speed Super Low Power SRAM
CS18LV02565
32K-Word By 8 Bit
GENERAL DESCRIPTION
The CS18LV02565 is a high performance, high speed and super low power CMOS Static Random
Access Memory organized as 32,768 words by 8bits and operates for a single 4.5 to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both high speed, super low power features
and maximum access time of 55/70ns in 5.0V operation. Easy memory expansion is provided by an
active LOW chip enable (/CE) and active LOW output enable (/OE).
The CS18LV02565 has an automatic power down feature, reducing the power consumption
significantly when chip is deselected. The CS18LV02565 is available in JEDEC standard 28-pin TSOP I
(8x13.4 mm), SOP (330 mil) and PDIP (600 mil) packages.
FEATURES
Wide operation voltage : 4.5 ~ 5.5V
Ultra low power consumption : 2mA＠1MHz (Max.) , Vcc=5.0V.
1.0 uA (Typ.) CMOS standby current
High speed access time : 55/70ns.
Automatic power down when chip is deselected.
Three state outputs and TTL compatible.
Data retention supply voltage as low as 1.5V.
Easy expansion with /CE and /OE options.

Input
Function
Address inputs for selecting one of the 32,768 x 8 bit words in the RAM
/CE is active LOW. Chip enable must be active when data read from or write
Input
/CE
to the device. If chip enable is not active, the device is deselected and in a
standby power mode. The DQ pins will be in high impedance state when the
device is deselected.
The Write enable input is active LOW. It controls read and write operations.
Input
/WE
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
Input
/OE
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.

3. Address valid prior to or coincident with CE transition low.
4. /OE = VIL.
5. Test conditions assume signal transition times of 5ns or less, timing reference levels of 0.5VCC, input
pulse levels of 0V to VCC and output loading specified in Figure 1A.
6. Transition is measured ±500mV from steady state with CL = 5pF as shown in Figure 1B. The parameter is

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.
TWR 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 = VIL ).DOUT is the same phase of write data of this write cycle.
7. DOUT is the read data of next address.
8. 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.
9. Test conditions assume signal transition times of 5ns or less, timing reference levels of 0.5VCC, input pulse
levels of 0V to VCC and output loading specified in Figure 1A.
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 /CE going low to the end of write.
