The 24AA32AT-I/MNY: A Robust 32K I2C Serial EEPROM Solution from Microchip

In the realm of embedded systems and IoT devices, the reliable and efficient storage of configuration data, calibration constants, or operational logs is paramount. The Microchip 24AA32AT-I/MNY stands out as a premier solution, offering designers a robust and highly versatile non-volatile memory component. This 32Kbit (4K x 8) serial EEPROM memory chip provides a critical balance of performance, density, and power efficiency, making it an ideal choice for a vast array of applications.

A key strength of this memory IC is its utilization of the ubiquitous I2C serial interface. This two-wire protocol minimizes the required number of microcontroller I/O pins, significantly simplifying board layout and reducing system cost. The 24AA32AT-I/MNY supports standard (100 kHz) and fast (400 kHz) mode operation, ensuring flexible and sufficiently speedy data transfer for most operational parameters and data logging tasks. For enhanced design flexibility, the device features hardware write-protection via a dedicated pin. When asserted, this feature locks the entire memory array, preventing any accidental writes and safeguarding critical data from corruption.

The chip is engineered for exceptional reliability, boasting an endurance of 1 million erase/write cycles and a data retention period of over 200 years. This ensures data integrity throughout the extended lifetime of the end product. Furthermore, its low-power design is critical for battery-sensitive applications. The 24AA32AT-I/MNY operates with a wide voltage range (1.7V to 5.5V) and features a standby current of just 1 μA (max.), making it perfectly suited for portable and power-conscious devices.

Housed in a space-saving 8-pin TDFN package, this EEPROM is designed for high-density PCB designs common in modern consumer electronics, medical devices, and industrial systems. Its extended temperature range (-40°C to +85°C) guarantees stable operation in environmentally challenging conditions.

ICGOODFIND: The Microchip 24AA32AT-I/MNY is a high-performance, reliable, and cost-effective serial EEPROM. Its combination of a simple I2C interface, robust data protection, exceptional endurance, and low-power operation establishes it as a default choice for engineers seeking dependable non-volatile memory in a compact form factor.
