• 1MHz to 10MHz clock rate depending on voltage
• Byte and Page Write capabilities (up to 16 bytes)
• Low power standby and active modes
• Data retention of over 100 years
• 1 million write/erase cycles minimum

Additional Specifications:

• Memory Type: EEPROM
• Interface Type: SPI
• Supply Voltage: 5.5V
• Memory Size: 4 Kbit
