7 / 35 page Am28F256A 7 PIN DESCRIPTION A0–A14 Address Inputs for memory locations. Internal latches hold addresses during write cycles. CE# (E#) Chip Enable active low input activates the chip’s control logic and input buffers. Chip Enable high will deselect the device and operates the chip in stand-by mode. DQ0-DQ7 Data Inputs during memory write cycles. Internal latches hold data during write cycles. Data Outputs during memory read cycles. NC No Connect-corresponding pin is not connected internally to the die. OE# (G#) Output Enable active low input gates the outputs of the device through the data buffers during memory read cycles. Output Enable is high during command sequencing and program/erase operations. VCC Power supply for device operation. (5.0 V ± 5% or 10%) VPP Program voltage input. VPP must be at high voltage in order to write to the command register. The command register controls all functions required to alter the mem- ory array contents. Memory contents cannot be altered when VPP ≤ VCC +2 V. VSS Ground. WE# (W) Write Enable active low input controls the write function of the command register to the memory array. The target address is latched on the falling edge of the Write En- able pulse and the appropriate data is latched on the ris- ing edge of the pulse. Write Enable high inhibits writing to the device. |
