Purchase A28F010, In-stock A28F010 From SeekIC.


| Symbol | Type | Name and Function |
| A0A16 | INPUT | ADDRESS INPUTS for memory addresses. Addresses are internally latched during a write cycle. |
| DQ0DQ7 | INPUT/OUTPUT | DATA INPUT/OUTPUT: Inputs data during memory write cycles; outputs data during memory read cycles. The data pins are active high and float to tri-state OFF when the chip is deselected or the outputs are disabled. Data is internally latched during a write cycle. |
| CEÝ | INPUT | CHIP ENABLE: Activates the device's control logic, input buffers, decoders and sense amplifiers. CEÝ is active low; CEÝ high deselects the memory device and reduces power consumption to standby levels. |
| OEÝ | INPUT | OUTPUT ENABLE: Gates the devices output through the data buffers during a read cycle. OEÝ is active low. |
| WEÝ | INPUT | WRITE ENABLE: Controls writes to the control register and the array. Write enable is active low. Addresses are latched on the falling edge and data is latched on the rising edge of the WEÝ pulse. Note: With VPP s 6.5V, memory contents cannot be altered. |
| VPP | ERASE/PROGRAM POWER SUPPLY for writing the command register, erasing the entire array, or programming bytes in the array. | |
| VCC | DEVICE POWER SUPPLY (5V g10%) | |
| VSS | GROUND | |
| NC | NO INTERNAL CONNECTION to device. Pin may be driven or left floating. |
