Instructions for Use
Power Supply:
- Connect VCC to the positive power supply (4.5V to 5.5V).
- Connect VSS to ground (0V).
Signal Connections:
- Address Lines (A0-A12): Connect these to the address bus of your system.
- Data Lines (D0-D7): Connect these to the data bus of your system.
- Chip Select (CS): Active low. When CS is low, the device is selected.
- Write Enable (WE): Active low. When WE is low, a write operation is performed.
- Output Enable (OE): Active low. When OE is low, the outputs are enabled.
Read Operation:
- Set the address lines to the desired memory location.
- Set CS and OE low to enable the device and the outputs.
- The data at the specified address will appear on the data lines after the access time (tAC).
Write Operation:
- Set the address lines to the desired memory location.
- Set the data lines to the data you want to write.
- Set CS and WE low to initiate the write operation.
- Maintain WE low for at least the write cycle time (tWC).
Standby Mode:
- Set CS high to put the device in standby mode, which reduces power consumption.
Temperature Considerations:
- Ensure that the operating temperature is within the specified range (-40°C to +85°C) to avoid damage or unreliable operation.
Handling:
- Handle the device with care to avoid static discharge, which can damage the chip.
- Follow standard ESD (Electrostatic Discharge) precautions when handling and installing the device.
