Microchip Technology, Inc. 512Kb 1.7V - 3.0V SPI Serial EEPROM 25A512

Description
The Microchip 25A512 is a 512 Kb Serial EEPROM utilizing the industry standard Serial Peripheral Interface (SPI) compatible serial bus. The device is organized as one block of 64K x 8-bit and is optimized for use in consumer electronics, industrial, medical, and automotive applications where reliable and dependable nonvolatile memory storage is essential. Software write protection allows the user to protect ¼, ½, or the entire memory array. A hardware write protect pin is also provided, which additionally protects against inadvertent writes to the status register. The EEPROM is available in a variety of space-saving packaging options. For product comparison, please consider: AT25512, 25AA512 Additional Features 64K x 8-bit (512 Kbit) Serial Peripheral Interface (SPI) Compatible Supports SPI modes 0 and 3 Up to 10 MHz clock frequency Self-Timed Erase and Write Cycles (5 ms max.) Low Power Consumption Read current: 10 mA (Max) at 10 MHz Write current: 5 mA (Max) at 10 MHz Standby current: 10 μA (Max) at 3.0V Deep power-down current: 1 μA (Max) at 2.5 V Block Write Protection: Protect 1/4, 1/2 or Entire Array More than 1 million erase/write cycles Data retention > 200 years Temperature Ranges Available Industrial (I): -40°C to +85°C Factory Programming Available Available in standard package 8-lead SOIC and advanced package 8-lead TSSOP
