Instructions for Use:

1. Power Supply Requirements: Ensure that the power supply voltage (Vdd and Vddq) is set to 2.5V ± 0.1V.
2. Temperature Considerations: The device operates reliably within a temperature range of -40°C to +85°C.
3. Installation: Install in a standard BGA socket or directly solder onto the PCB as per the manufacturer’s guidelines.
4. Initialization: Upon powering up, initialize the SDRAM with the appropriate command sequence according to the JEDEC standard.
5. Refresh Commands: Issue refresh commands every 64ms to maintain data integrity.
6. Timing Parameters: Adhere strictly to the specified timing parameters (tRCD, tRP, tRC) to ensure reliable operation.
7. Signal Integrity: Pay attention to signal integrity by using proper PCB layout techniques, especially for high-speed signals.
8. Handling Precautions: Handle the component with care to avoid damage from electrostatic discharge (ESD).
