AT25512N-SH-B

The AT25512N-SH-B is a 512kB high-speed SPI bus Serial EEPROM IC supports byte write and SPI modes 0 and 3 operations. The EEPROM is organized as 65,536 x 8. Optimized for applications where low-power and low-voltage operations are essential. The EEPROM is available in a variety of space-saving packaging options at 1.8V (VCC = 1.8 to 5.5V). The 3-wire serial interface consists of a data input, output and a shift clock. All programming cycles are completely self-timed and no separate erase cycle is required before write. Block write protection is program enabled and separate program enable and disable instructions are provided for additional data protection. Hardware data protection provided to protect against inadvertent write attempts to the status register. Any serial communication suspension can be accomplished without resetting the serial sequence. Write Protect (WP) Pin and write disable instructions for both hardware and software data protection.

• Serial peripheral interface (SPI) compatible
• Supports SPI modes 0 (0, 0) and 3 (1, 1)
• 20MHz Clock rate (4.5 to 5.5V)
• Block write protection - Protect 1/4, 1/2 or entire array
• Self-timed write cycle (5ms maximum)
• High reliability - 1,000,000 write cycles endurance
• Halogen-free
