24AA256-I/P in Microchip 24LC/24AA EEPROMs Family
The 24AA256-I/P is a member of Microchip Technology's 256Kbit I2C serial EEPROM family, designed for low-power non-volatile memory storage. Organized as 32K x 8-bit blocks, this specific variant operates over a wide voltage range of 1.7V to 5.5V and utilizes a standard 8-pin PDIP package. It is primarily used for storing configuration constants, calibration data, and system parameters in embedded designs where space is available for through-hole components and reliable data retention is critical.
Variants in This Sub-Family
Variants within the 24AA256 sub-family primarily differ by package type, temperature rating, and supply voltage specifications. While the 24AA256-I/P denotes an Industrial temperature range (-40C to +85C) in a PDIP package, other variants like the 24LC256 offer higher clock speeds at 5V. Package options extend to SOIC, TSSOP, and MSOP for high-density surface-mount designs, though all share the same logical I2C addressing and page-write protocols.
