Instructions for SST26VF032B-104I/SM

1. Initialization

• Power-Up Sequence:
  • Apply Vcc to the device.
  • Ensure Vcc is stable before applying any commands or data.

2. Read Operations

• Read Array Command:
  • Send command 0x03 (Read Data) to the device.
  • Provide the starting address (24-bit).
  • The device will output the data starting from the specified address.

3. Write Operations

• Write Enable:
  • Send command 0x06 (Write Enable) to allow write operations.
• Page Program:
  • Send command 0x02 (Page Program).
  • Provide the starting address (24-bit).
  • Send the data to be programmed (up to 256 bytes per page).

4. Erase Operations

• Sector Erase:
  • Send command 0x20 (Sector Erase).
  • Provide the starting address (24-bit) of the sector to be erased (4KB).
• Block Erase:
  • Send command 0x52 (32KB Block Erase).
  • Provide the starting address (24-bit) of the block to be erased (32KB).
• Chip Erase:
  • Send command 0xC7 (Chip Erase) to erase the entire chip.

5. Status Register Operations

• Read Status Register:
  • Send command 0x05 (Read Status Register) to read the status register.
• Write Status Register:
  • Send command 0x01 (Write Status Register) followed by the new status register value.

6. Protecting Memory

• Write Protect:
  • Set the Write Protect (WP) pin high to prevent accidental writes.
• Software Protection:
  • Use the status register to set block protection bits.

7. Deep Power-Down Mode

• Enter Deep Power-Down:
  • Send command 0xB9 (Deep Power-Down).
• Exit Deep Power-Down:
  • Any valid command will exit deep power-down mode.

8. Error Handling

• Check Status Register:
  • After write or erase operations, check the status register to ensure the operation was successful.
• Handle Failures:
  • If an error is detected, retry the operation or reset the device.

9. Timing Considerations

• Ensure Timing:
  • Follow the timing specifications for read, write, and erase operations to avoid data corruption.
• Polling:
  • Use polling to check the status register after write or erase operations to ensure they have completed.

10. Package Information

• Package Type:
  • SOIC-8, TSSOP-8, WSON-8
• Pin Configuration:
  • Refer to the datasheet for detailed pin configurations and pin functions.
