Unlocking High-Density Data Storage: The Microchip 24AA256-I/SN 256K I2C Serial EEPROM

In the realm of embedded systems and data storage, the Microchip 24AA256-I/SN stands out as a highly reliable and efficient solution for non-volatile memory needs. This 256K I2C serial EEPROM memory chip is engineered to meet the demands of applications requiring robust, low-power, and compact data storage. With its I2C serial interface, it simplifies communication with microcontrollers, reducing wiring complexity and board space while enabling seamless integration into diverse electronic designs.

The 24AA256 offers a 256Kbit (32KB) memory array, organized as 32,768 words of 8 bits each. This capacity makes it suitable for storing configuration data, calibration constants, or event logs in systems ranging from consumer electronics to industrial automation. Its endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years ensure long-term reliability, critical for applications where data integrity is paramount.

Operating at voltages from 1.7V to 5.5V, the chip supports broad compatibility with various logic levels, while its low standby current consumption (typically 1 μA) makes it ideal for battery-powered devices. The built-in hardware write-protection feature safeguards memory contents against accidental writes, enhancing system security. Additionally, the 24AA256-I/SN supports page write operations of up to 64 bytes, optimizing data transfer efficiency.

Housed in an 8-lead SOIC package, this EEPROM is designed for space-constrained environments. Its extended temperature range (-40°C to +85°C) ensures performance in harsh conditions, catering to automotive, medical, and industrial applications. The self-timed write cycle simplifies firmware development by eliminating the need for software polling.
