2 / 9 page BSI BH62UV1600 R0201-BH62UV1600 Revision 1.0 Jul. 2005 2 n PIN DESCRIPTIONS Name Function A0-A20 Address Input These 21 address inputs select one of the 2,048K x 8 bit in the RAM 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. 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 impendence state when OE is inactive. DQ0-DQ7 Data Input/Output Ports 8 bi-directional ports are used to read data from or write data into the RAM.

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. –2.0V in case of AC pulse width less than 30 ns n OPERATING RANGE RANG AMBIENT TEMPERATURE VCC Commercial 0 OC to + 70OC 1.65V ~ 3.6V Industrial -25 OC to + 85OC 1.65V ~ 3.6V n CAPACITANCE (1) (T A = 25 OC, f = 1.0MHz) SYMBOL PAMAMETER CONDITIONS MAX.
