Key Features

  • 2 Kbit (256 × 8-bit) I2C EEPROM with 400 kHz fast-mode clock and hardware address pins supporting up to 8 devices on a single bus
  • Endurance of 1,000,000 write/erase cycles per byte with data retention exceeding 200 years for reliable non-volatile storage
  • Compact TSSOP-8 package with wide supply voltage range enabling easy integration in space-constrained and low-power embedded systems

Applications

The 24AA024H-I/ST is suited for storing calibration constants, configuration parameters, and serial number data in consumer electronics, industrial sensors, and medical instruments. Its I2C interface at up to 400 kHz allows efficient multi-device bus sharing, reducing pin count on tight board layouts. The high endurance of 1,000,000 cycles makes it reliable for frequently updated logs or trim values in mixed-signal designs.

Frequently Asked Questions

How many bytes can the 24AA024H-I/ST store and how is its memory organized?

The 24AA024H-I/ST provides 2 Kbit of non-volatile storage organized as 256 bytes, addressed over I2C using the control byte 1010DDDR. Up to 8 devices can share a single bus using the 3 hardware address pins, giving a combined capacity of 16 Kbit on one I2C line.

What is the maximum I2C clock frequency the 24AA024H-I/ST supports for fast communication?

The device supports I2C clock frequencies up to 400 kHz in fast mode, enabling rapid sequential reads and writes in data-logging or calibration applications. This allows a full 256-byte sequential read to complete in well under 10 ms at 400 kHz, keeping host MCU overhead low.

How does the write endurance of the 24AA024H-I/ST compare to standard EEPROM in high-update-rate systems?

With 1,000,000 guaranteed write/erase cycles per byte, the 24AA024H-I/ST outlasts many standard EEPROMs rated at only 100,000 cycles, making it a better fit for systems that update trim values or event counters dozens of times per day over a 10-year product life.
