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. „ PRODUCT FAMILY PRODUCT FAMILY BS62LV4007TC BS62LV4007STC BS62LV4007SC BS62LV4007EC BS62LV4007PC BS62LV4007TI BS62LV4007STI BS62LV4007SI BS62LV4007EI BS62LV4007PI OPERATING TEMPERATURE Vcc RANGE SPEED ( ns ) 55ns :4.5~5.5V 70ns :4.5~5.5V POWER DISSIPATION ( I CCSB1 , Max ) STANDBY Vcc =5.0V Operating ( I CC , Max ) Vcc = 5.0V 55ns Vcc =5.0V 70ns PKG TYPE TSOP - 32 STSOP -32 SOP - 32 TSOP2 - 32 PDIP - 32 TSOP - 32 STSOP - 32 SOP - 32 TSOP2 - 32 PDIP - 32 +0 C to +70 C O O 4.5V ~ 5.5V 55 / 70 30uA 68mA 58mA - 40 O C to +85 C O 4.5V ~ 5.5V 55 / 70 60uA 70mA 60mA „ PIN CONFIGURATIONS A18 A16 A14 A12 A7 A6 A5 A4 A3 A2 A1 A0 DQ0 DQ1 DQ2 GND 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 VCC A15 A17 WE A13 A8 A9 A11 OE A10 CE DQ7 DQ6 DQ5 DQ4 DQ3 „ BLOCK DIAGRAM A13 A17 A15 A18 A16 A14 A12 A7 A6 A5 A4 • BS62LV4007SC BS62LV4007SI BS62LV4007EC BS62LV4007EI BS62LV4007PC BS62LV4007PI Address Input Buffer 22 Row Decoder 2048 Memory Array 2048 X 2048 2048 DQ0 DQ1 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 8 Data Input Buffer 8 Column I/O Write Driver Sense Amp 256 Column Decoder 16 CE WE OE Vdd GND A11 A9 A8 A3 A2 A1 A0 A10 Control Address Input Buffer 8 A11 A9 A8 A13 WE A17 A15 VCC A18 A16 A14 A12 A7 A6 A5 A4 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 BS62LV4007TC BS62LV4007STC BS62LV4007TI BS62LV4007STI 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 OE A10 CE DQ7 DQ6 DQ5 DQ4 DQ3 GND DQ2 DQ1 DQ0 A0 A1 A2 A3 Data Output Buffer 8 Brilliance Semiconductor, Inc. reserves the right to modify document contents without notice.
