Key Features
- 1.8 V to 5.5 V operating range for compatibility with modern low-voltage MCU systems
- 400 kHz Fast-mode I2C interface reduces firmware complexity for non-volatile data storage
- Compact MSOP-8 package saves board space in space-constrained portable and IoT designs
Applications
24AA16-I/MS is ideal for storing configuration data, calibration coefficients, and user settings in microcontroller-based systems such as IoT sensor nodes, consumer electronics, and industrial instruments. Its 1.8 V operation makes it a natural companion for ultra-low-power MCUs like PIC and ARM Cortex-M0 devices. The small MSOP-8 footprint and simple 2-wire I2C interface minimize both PCB area and firmware overhead.

Frequently Asked Questions
What I2C bus speed does the 24AA16-I/MS support, and how many devices can share the same bus?
The 24AA16-I/MS supports Standard-mode at 100 kHz and Fast-mode at 400 kHz I2C communication. Up to 8 devices can be addressed on a single bus using the 3-bit hardware address pins A0–A2, giving a maximum of 128 Kbits (16 KB) of total addressable EEPROM storage per I2C segment. This bus-sharing capability reduces pin count on the host microcontroller.
How does the page write buffer size of 24AA16-I/MS affect write throughput in a data-logging design?
The 24AA16-I/MS has a 16-byte page write buffer, meaning up to 16 bytes can be sent in a single I2C transaction before the internal write cycle begins. The self-timed write cycle completes in a maximum of 5 ms, after which the bus master can poll for acknowledgment. For a data-logging application writing 64-byte records, only 4 page writes are needed, keeping average write latency under 20 ms.
What is the endurance and data retention rating of the 24AA16-I/MS for industrial applications?
Microchip specifies the 24AA16-I/MS for a minimum of 1,000,000 write cycles per memory location and 200 years of data retention at 25°C. The industrial temperature range of -40°C to +85°C ensures reliable operation in harsh environments such as outdoor sensor units, automotive accessories, and factory automation equipment.
Is 24AA16-I/MS a suitable drop-in alternative to AT24C16 from other vendors?
Yes, the 24AA16-I/MS is functionally compatible with standard 16 Kbit I2C EEPROMs like the AT24C16, sharing the same 2K x 8-bit organization, 8-pin pinout, and 400 kHz I2C interface. The key advantage is its lower minimum supply voltage of 1.8 V versus the 2.5 V or 2.7 V minimums common in older 24C16 variants, making it preferable in 1.8 V MCU subsystems.
