Instructions

1. Power Supply:

   • Connect the V_CC pin to a 5V power supply.
   • Connect the GND pin to ground.

2. Address Lines:

   • Connect the address lines (A0-A15) to the appropriate address bus lines of your microcontroller or CPU.

3. Data Lines:

   • Connect the data lines (D0-D15) to the data bus lines of your microcontroller or CPU.

4. Control Signals:

   • Chip Select (CS): Connect this pin to the chip select signal from your microcontroller. When CS is low, the SRAM is active.
   • Write Enable (WE): Connect this pin to the write enable signal from your microcontroller. When WE is low, data is written to the SRAM.
   • Output Enable (OE): Connect this pin to the output enable signal from your microcontroller. When OE is low, data is read from the SRAM.

5. Timing Considerations:

   • Ensure that the setup and hold times for address and data lines are met as specified in the parameter table.
   • The access time (t_AA) should be considered when designing the timing of your read and write operations.

6. Standby Mode:

   • To enter standby mode, set the CS pin high. This will reduce the current consumption of the SRAM.

7. Operating Temperature:

   • The device is designed to operate within the industrial temperature range of -40°C to +85°C.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Use proper grounding and ESD protection when handling the device.

By following these instructions and adhering to the specified parameters, you can ensure reliable operation of the MC68LC302PU16CT SRAM in your application.
