AT25256B in 25LCxx / AT25 SPI EEPROM Family
The AT25256B is a 256-Kbit Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) family manufactured by Microchip Technology. Designed for industrial and commercial applications, these devices utilize a Serial Peripheral Interface (SPI) to provide high-speed non-volatile data storage. They are characterized by their reliability, featuring high endurance and long data retention cycles, making them a standard choice for systems requiring robust parameter storage and frequent configuration updates.
Variants in This Sub-Family
The AT25256B sub-family variants primarily differ based on their physical packaging and temperature grading. Available packages include the 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN, and 8-ball VFBGA. Additionally, variants are distinguished by their operating temperature ranges, such as industrial (-40°C to +85°C) and extended industrial (-40°C to +125°C), allowing engineers to select the specific footprint and thermal performance required for their PCB design.
