BSI FEATURES Very Low Power/Voltage CMOS SRAM 256K x 16 or 512K x 8 bit switchable DESCRIPTION BS616LV4020 • Very low operation voltage : 2.7 ~ 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 BS616LV4020 is a high performance, very low power CMOS Static Random Access Memory organized as 262,144 words by 16 bits or 524,288 bytes by 8 bits selectable by CIO pin and operates from a wide range of 2.7V 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 3V operation. Easy memory expansion is provided by active HIGH chip enable2(CE2), active LOW chip enable1(CE1), active LOW output enable(OE) and three-state output drivers. The BS616LV4020 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The BS616LV4020 is available in DICE form and 48-pin BGA type.

This address input incorporates with the above 18 address input select one of the 524,288 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. 262,144 x 16-bit words configuration is selected if CIO is HIGH. 524,288 x 8-bit bytes configuration is selected if CIO is LOW. CE1 Chip Enable 1 Input CE2 Chip Enable 2 Input 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. WE Write Enable Input OE Output Enable Input 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. LB and UB Data Byte Control Input DQ0 - DQ15 Data Input/Output Ports Vcc Gnd Lower byte and upper byte data input/output control pins. The chipis 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.

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 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 = 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 = 30pF 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.
