SO Pin Connections Warning: DU = Don’t Use. PIN DESCRITPION Addresses (A0-A12). The address inputs select an 8-bit memory location during a read or write operation. Chip Enable (E). The chip enable input must be low to enable all read/write operations. When Chip Enable is high, power consumption is reduced. Output Enable (G). The Output Enable input con- trols the data output buffers and is used to initiate read operations. 2/15 M28C64C, M28C64X |
