CMOS standby current • High speed access time : -55 55ns -70 70ns • Automatic power down when chip is deselected • Fully static operation • Data retention supply voltage as low as 1.5V • Easy expansion with CE and OE options • Three state outputs and TTL compatible The BS62LV4007 is a high performance, very low power CMOS Static Random Access Memory organized as 524,288 words by 8 bits and operates from a range of 4.5V to 5.5V supply voltage. Advanced CMOS technology and circuit techniques provide both high speed and low power features with a typical CMOS standby current of 2.0uA at 5.0V/25oC and maximum access time of 55ns at 5.0V/85oC. Easy memory expansion is provided by an active LOW chip enable (CE) , and active LOW output enable (OE) and three-state output drivers. The BS62LV4007 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The BS62LV4007 is available in the JEDEC standard 32L SOP, TSOP , PDIP, TSOP II and STSOP package.

R0201-BS62LV4007 • 1 Revision 1.1 Jan. 2004 BSI PIN DESCRIPTIONS BS62LV4007 Function These 19 address inputs select one of the 524,288 x 8-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. Name A0-A18 Address Input CE Chip Enable Input WE Write Enable Input 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. 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. DQ0-DQ7 Data Input/Output Ports Vcc GND These 8 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 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 ). 7. DOUT is the same phase of write data of this write cycle. 8. DOUT is the read data of next address. 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. The parameter is guaranteed but not 100% tested. 11. TCW is measured from the later of CE going low to the end of write.
