Instructions
1. Power Supply
- VCC: Connect to a stable power supply within the range of 2.7V to 3.6V.
- GND: Ensure a solid ground connection to avoid noise and instability.
2. Pin Configuration
- A0-A19: Address lines (20 bits).
- D0-D7: Data lines (8 bits).
- /OE: Output Enable (active low).
- /WE: Write Enable (active low).
- /CE: Chip Enable (active low).
3. Basic Operation
- Reading Data:
- Set /CE and /OE low.
- Apply the desired address to A0-A19.
- Data will be available on D0-D7 after tAA.
- Writing Data:
- Set /CE and /WE low.
- Apply the desired address to A0-A19.
- Apply the data to D0-D7.
- Maintain /WE low for at least tWC.
- Data will be written to the memory.
4. Timing Diagrams
- Read Cycle:
- /CE and /OE go low.
- Address is applied to A0-A19.
- After tAA, data is valid on D0-D7.
- Write Cycle:
- /CE and /WE go low.
- Address is applied to A0-A19.
- Data is applied to D0-D7.
- /WE remains low for tWC.
- Data is written to the memory.
5. Power-Up and Power-Down Sequences
- Power-Up:
- Apply VCC and ensure it is stable before enabling the chip.
- Initialize /CE, /OE, and /WE to high (inactive) state.
- Power-Down:
- Set /CE, /OE, and /WE to high (inactive) state.
- Remove VCC when the device is not needed.
6. Handling and Storage
- ESD Protection: Handle with care to avoid electrostatic discharge.
- Storage: Store in a dry, cool place to prevent moisture damage.
This table and the instructions should help you effectively use the XCS20TQ144CKN in your applications.
