See all from this product rangeProduct Overview
The AT25640B-SSHL-B is a 65536-bit standard SPI serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 8192 words of 8-bit each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. It is enabled through the chip select pin and accessed via a 3-wire interface consisting of serial data input, serial data output and serial clock. All programming cycles are completely self-timed and no separate erase cycle is required before write. Block write protection is enabled by programming the status register with one of four blocks of write protection. Separate program enable and program disable instructions are provided for additional data protection. Hardware data protection is provided via the WP pin to protect against inadvertent write attempts to the status register. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence.
- Supports SPI modes
- Low and standard-voltage operation

- Block write protection - Protect 1/4, 1/2 or entire array
- Write protect pin and write disable instructions for both hardware and software data protection
- Self-timed write cycle (5ms maximum)
- High-reliability
- Endurance - 1000000 write cycles
- Data retention - 100 years
