AT24MAC402-SSHM-B Description

Short technical summary and product information.

The AT24MAC402-SSHM-B from Microchip Technology is a 2Kbit (256 x 8) Serial Electrically-Erasable Programmable Read-Only Memory (EEPROM) accessed via an I2C-compatible two-wire serial interface. It supports clock frequencies up to 1MHz with an access time of 550ns and operates over a wide voltage range of 1.7V to 5.5V.

 

This EEPROM offers high reliability with an endurance of 1,000,000 write cycles and data retention for 100 years. It includes features such as Schmitt trigger filtered inputs for noise suppression and a write protect pin for hardware data protection. The device is available in an 8-SOIC surface mount package.

 

Enhanced features include a factory-programmed, permanently locked, read-only EUI-48 compatible address and a unique factory-programmed 128-bit serial number, both stored in a separate memory area. These features are valuable for device identification and tracking in various embedded systems.

 

The operating temperature range for the AT24MAC402-SSHM-B is -40°C to 85°C (TA). It is suitable for applications requiring non-volatile data storage with a standard I2C interface.
