AT25640B-XHL-T Description

Short technical summary and product information.

The Atmel AT25640B-XHL-T is a 64Kb (65,536 bits) Serial Peripheral Interface (SPI) EEPROM. Organized as 8192 words of 8 bits each, it is optimized for low-power and low-voltage industrial and commercial applications.

 

This device supports SPI Modes 0 and 3 and operates with a clock rate of up to 20MHz at 5V. It features a 32-byte page mode and block write protection for data security. The AT25640B-XHL-T boasts high reliability with an endurance of 1,000,000 write cycles and an impressive data retention of 100 years.

 

It is available in an 8-lead SOIC package, suitable for surface mount applications. The device operates within a wide temperature range of -55°C to +125°C and supports a voltage range from 1.8V to 5.5V, with a maximum operating voltage of 6.25V.

 

This EEPROM includes hardware and software data protection features, such as a Write Protect (WP) pin and Write Disable instructions. The self-timed write cycle is a maximum of 5ms. It is also noted for its green packaging options, being Pb/Halide-free and RoHS compliant.
