The 24AA16T-I/SN: A Robust 16K 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 parameters is paramount. The 24AA16T-I/SN from Microchip Technology stands out as a premier solution for these non-volatile memory needs. This 16 Kbit (2048 x 8) serial EEPROM memory chip combines industry-standard architecture with enhanced reliability features, making it an excellent choice for a vast array of applications.

A key strength of this IC is its utilization of the ubiquitous I2C serial interface. This two-wire protocol minimizes the required number of microcontroller I/O pins for communication, simplifying board design and reducing system cost. The 24AA16T supports both standard (100 kHz) and fast (400 kHz) mode operation, providing flexibility for various speed requirements. With its 16-bit address space, it efficiently organizes its memory as a single block of 2048 bytes.

Designed for resilience, this EEPROM is built to withstand demanding operating conditions. It features a 1,000,000 erase/write cycle endurance and boasts data retention of over 200 years, ensuring the integrity of critical information throughout the lifetime of the product. Its wide voltage range operation (1.7V to 5.5V) makes it perfectly suited for both low-power battery-operated devices and standard 5V or 3.3V systems. The device also includes hardware write-protection via a dedicated pin, safeguarding memory contents from accidental or erroneous writes.

The 24AA16T-I/SN is offered in a compact 8-lead SOIC (SN) package, ideal for space-constrained PCB designs. Its extended industrial temperature range (-40°C to +85°C) ensures reliable performance in harsh environments, from industrial automation to automotive applications. Common uses include storing data in smart sensors, medical devices, consumer electronics, and networking equipment.

ICGOODFIND: The Microchip 24AA16T-I/SN is a highly reliable and versatile serial EEPROM, offering an optimal blend of standard I2C compatibility, exceptional endurance, and low-power operation in a miniature package, making it a top-tier choice for designers.
