Microchip 24AA32AFT-I/MS: A Compact 32K I2C Serial EEPROM in MSOP Package

In the realm of embedded systems and data storage, the Microchip 24AA32AFT-I/MS stands out as a highly reliable and efficient 32K I2C serial EEPROM solution. Housed in a compact MSOP package, this device is engineered for applications where space, power, and reliability are critical constraints.

The 24AA32AFT offers 32 kilobits (4 Kbytes) of electrically erasable programmable read-only memory (EEPROM), organized as 4096 words of 8 bits each. It operates across a broad voltage range (1.7V to 5.5V), making it suitable for both low-power and mainstream applications, from consumer electronics to industrial systems. Its I2C-compatible serial interface supports clock speeds of up to 400 kHz for standard mode and 1 MHz for fast mode plus, ensuring efficient and flexible data transfer.

A key feature of this EEPROM is its high endurance and data retention, capable of supporting over 1 million erase/write cycles and retaining data for more than 200 years. These characteristics make it ideal for storing critical parameters, calibration data, or user settings in systems requiring frequent updates and long-term reliability.

The device also incorporates hardware write-protection via a dedicated pin, preventing accidental data modification. Additionally, it supports page write operations of up to 32 bytes, streamlining data storage processes and reducing host processor overhead.

Packaged in an MSOP-8 format, the 24AA32AFT-I/MS is optimized for space-constrained PCB designs, offering a minimal footprint without compromising performance. Its extended temperature range (-40°C to +85°C) ensures robust operation in harsh environments.

ICGOOODFIND: The Microchip 24AA32AFT-I/MS combines high density, low power consumption, and robust packaging, making it a versatile choice for modern embedded storage needs.
