Instructions for Using AT45DB081D-SU
Power Supply:
- Ensure the supply voltage (VCC) is within the specified range of 2.7V to 3.6V.
- Connect the ground (GND) pin to the system ground.
Initialization:
- After power-up, wait for at least 100 microseconds before sending any commands to the device.
- Set the chip select (CS) pin to low to activate the device.
Command Sequence:
- Use the serial input/output (SI/O) pin to send commands and data.
- Commands are typically 8-bit sequences followed by address or data as required.
- Refer to the command set in the datasheet for specific command codes and their functions.
Reading Data:
- Send the read command (e.g., 0x51 for Read Data) followed by the address of the first byte to be read.
- The device will output the data on the SI/O pin.
Writing Data:
- Send the write command (e.g., 0x82 for Page Program) followed by the address of the first byte to be written.
- Send the data to be programmed to the device.
- Wait for the programming time (3.5 ms) before sending another command.
Erasing Blocks:
- Send the block erase command (e.g., 0x50 for Block Erase) followed by the address of the first byte of the block to be erased.
- Wait for the erase time (40 ms) before sending another command.
Status Check:
- Use the status register read command (e.g., 0x70 for Read Status Register) to check the status of the device.
- The status register indicates whether the device is busy or ready for the next operation.
Power Down:
- When not in use, set the CS pin to high to put the device into standby mode, reducing current consumption.
- Before powering down, ensure all operations are completed and the device is in a known state.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal circuits.
- Store the device in a dry, cool place when not in use.
