2 / 10 page ![]() 2 V61C3181024 Rev. 1.3 February 1999 MOSEL VITELIC V61C3181024 Pin Descriptions A0–A16 Address Inputs These 17 address inputs select one of the 128K x 8 bit segments in the RAM. CE1, CE2 Chip Enable Inputs CE1 is active LOW and CE2 is active HIGH. Both chip enables must be active to read from or write to the device. If either chip enable is not active, the device is deselected and is in a standby power mode. The I/O pins will be in the high-impedance state when deselected. OE Output Enable Input The Output Enable input is active LOW. When OE is LOW with CE LOW and WE HIGH, data of the selected memory location will be available on the I/O pins. When OE is HIGH, the I/O pins will be in the high impedance state. WE Write Enable Input An active LOW input, WE input controls read and write operations. When CE and WE inputs are both LOW, the data present on the I/O pins will be written into the selected memory location. I/O0–I/O7 Data Input and Data Output Ports These 8 bidirectional ports are used to read data from and write data into the RAM.
