What are the key features of 24AA014H-I/ST?
- 1,000,000 write/erase cycle endurance ensures long-lasting non-volatile storage in high-frequency write applications
- 1.8 V operation enables direct integration with low-voltage MCUs and SoCs without level-shifting circuitry
- I2C interface at up to 400 kHz with configurable 2-wire address (1010DDDR) supports up to 8 devices on a single bus
- 200-year minimum data retention in compact TSSOP-8 package for cost-effective configuration and calibration storage
What is 24AA014H-I/ST used for?
The 24AA014H-I/ST is designed for non-volatile storage of device configuration, calibration coefficients, and small parameter tables in microcontroller-based systems operating from 1.8 V supply rails. Its 400 kHz I2C interface with configurable device address allows up to 8 independent EEPROMs to share a single 2-wire bus, which is useful in multi-sensor arrays and module identification applications. The 1 Mbit endurance rating and 200-year data retention also make it suitable for firmware versioning, user preference storage, and security key backup in IoT edge devices, wearable electronics, and smart sensor modules.

Frequently Asked Questions
How many write cycles does the 24AA014H-I/ST support, and does this limit its use in logging applications?
The 24AA014H-I/ST is rated for 1,000,000 write/erase cycles per memory location. For a data logging application that writes one byte to the same address every second, this endurance corresponds to over 11 days of continuous operation before wear-out at that address. However, for typical configuration and calibration storage where writes occur once or a few times during device lifetime, the 1,000,000 cycle rating is far more than sufficient. Address wear-leveling algorithms can further extend effective lifespan if frequent writes across the 128-byte address space are required.
What minimum supply voltage does the 24AA014H-I/ST support, and how does this benefit 1.8 V MCU designs?
The 24AA014H-I/ST operates from a supply voltage as low as 1.8 V, making it directly compatible with low-voltage MCUs and SoCs that operate from single-cell lithium-ion batteries or 1.8 V regulated rails. Unlike 2.5 V or 3.3 V EEPROMs that require level shifters or boost regulators when paired with a 1.8 V processor, the 24AA014H connects directly to the MCU's I2C pins without additional voltage translation, saving one or two external components and reducing the power budget by eliminating level-shifter quiescent current.
How many 24AA014H-I/ST devices can be connected on a single I2C bus, and how are they addressed?
Up to 8 individual 24AA014H-I/ST devices can share a single I2C bus by using the 3 configurable address bits in the I2C control byte (1010DDDR format), where the D bits are set by the hardware address pins A0, A1, and A2 on the device. Each combination of 3 address pin states creates a unique 7-bit I2C address, allowing 8 independent 1 Kbit EEPROMs totaling 8 Kbits on one 2-wire bus. This feature is valuable in multi-channel sensor calibration systems and modular hardware designs where each module carries its own identification EEPROM.
What is the procurement lead time for 24AA014H-I/ST, and how does its TSSOP-8 package support automated assembly?
The 24AA014H-I/ST has a factory lead time of 5 weeks, which is among the shortest available for EEPROM devices and allows responsive replenishment without large safety stock. The TSSOP-8 package (1.75 mm pitch, 3 mm body width) is a standard form factor handled by common pick-and-place equipment and is compatible with lead-free reflow profiles per IPC-7711. The tape-and-reel format (ST suffix) supports high-volume automated SMT assembly, and the RoHS Pb-free e3 finish meets European and Asian environmental regulations for consumer and industrial product certifications.
