R0201-BH62UV8001 Revision 1.1 1 May 2006 BH62UV8001 n PIN DESCRIPTIONS Name Function These 20 address inputs select one of the 1,048,576 x 8 bit in the RAM A0-A19 Address Input CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active when CE1 Chip Enable 1 Input data read from or write to the device. If either chip enable is not active, the device is CE2 Chip Enable 2 Input 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 WE Write Enable Input 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 OE Output Enable Input 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.
