BSI n FEATURES Ultra Low Power/High Speed CMOS SRAM 1M X 8 bit n DESCRIPTION BH62UV8000 Y Wide VCC low operation voltage : 1.65V ~ 3.6V Y Ultra low power consumption : VCC = 3.0V Operation current : 5.0mA at 70ns at 25OC 1.5mA at 1MHz at 25OC Standby current : 2.5uA at 25OC VCC = 2.0V Data retention current : 2.5uA at 25OC Y High speed access time : -70 70ns at 1.8V at 85OC Y Automatic power down when chip is deselected Y Easy expansion with CE1, CE2 and OE options Y Three state outputs and TTL compatible Y Fully static operation, no clock, no refreash Y Data retention supply voltage as low as 1.0V The BH62UV8000 is a high performance, ultra low power CMOS Static Random Access Memory organized as 1,048,576 by 8 bits and operates in a wide range of 1.65V to 3.6V supply voltage. Advanced CMOS technology and circuit techniques provide both high speed and low power features with typical operating current of 1.5mA at 1MHz at 3.6V/25OC and maximum access time of 70ns at 1.8V/85OC. Easy memory expansion is provided by an active LOW chip enable (CE1), an active HIGH chip enable (CE2) and active LOW output enable (OE) and three-state output drivers. The BH62UV8000 has an automatic power down feature, reducing the power consumption significantly when chip is deselected. The BH62UV8000 is available in DICE form and 48-ball BGA package. n PRODUCT FAMILY PRODUCT FAMILY OPERATING TEMPERATURE VCC RANGE SPEED (ns) VCC=1.8~3.6V POWER CONSUMPTION STANDBY (ICCSB1, Max) Operating (ICC, Max) PKG TYPE VCC=3.6V VCC=1.8V VCC=3.6V VCC=1.8V +0OC to +70OC BH62UV8000AI 1.65V ~ 3.6V BH62UV8000DI -25OC to +85OC 70 13uA 10uA 10mA 7mA BGA-48-0608 DICE 70 15uA 12uA 10mA 7mA n PIN CONFIGURATIONS 1 A NC 2 OE 3 A0 4 A1 5 A2 6 CE2 n BLOCK DIAGRAM B NC NC A3 A4 CE1 NC C DQ0 NC A5 A6 NC D04 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 Address Input Buffer 10 Row Decoder 1024 Memory Array 1024 x 18192 D VSS DQ1 A17 A7 DQ5 VCC DQ0 DQ1 8 Data Input Buffer 8 8 8192 Column I/O Write Driver Sense Amp 1024 Column Decoder 10 Control Address Input Buffer E VCC DQ2 VSS A16 DQ6 VSS DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 8 F D3 NC A14 A15 NC DQ7 Data Output Buffer G NC NC A12 A13 WE NC CE1 CE2 WE OE VCC GND H A18 A8 A9 A10 A11 A19 A19 A18 A17 A15 A14 A13 A16 A2 A1 A0 48-ball BGA top view Brilliance Semiconductor, Inc. reserves the right to modify document contents without notice.

R0201-BH62UV8000 1 Revision 1.0 Jul. 2005 BSI n PIN DESCRIPTIONS BH62UV8000 Function These 20 address inputs select one of the 1,048,576 x 8 bit in the RAM Name A0-A19 Address Input 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 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 impendence state when OE is inactive. 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 CE1 and CE2 active 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 CE1 or WE going high or CE2 going low 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 CE1 low transition or the CE2 high 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 CE1 is low and CE2 is high 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 = 5pF. The parameter is guaranteed but not 100% tested. 11. tCW is measured from the later of CE1 going low or CE2 going high to the end of write.
