What are the key features of 24LC024H-I/SN?
- 1 MHz fast-mode I2C interface with 1010DDDR control byte allowing up to 4 devices on a single bus using address pins
- 1,000,000 write/erase endurance cycles with 200-year data retention rating for reliable long-term configuration storage
- Ultra-wide 1.7 V to 5.5 V supply range enabling use in 1.8 V, 3.3 V, and 5 V microcontroller systems without level shifting
What is 24LC024H-I/SN used for?
24LC024H-I/SN is used in embedded systems for storing non-volatile configuration parameters, calibration coefficients, and device serial numbers in a 2 Kbit capacity that suits most small-footprint IoT and industrial sensor nodes. Its 1 MHz I2C interface allows rapid firmware updates to stored settings during factory programming without a dedicated programming interface. Smart meter modules, wearable medical devices, and HVAC control boards rely on its 1,000,000-cycle endurance and 200-year retention to survive the product service lifetime.

Frequently Asked Questions
How many bytes can 24LC024H-I/SN store and how is the memory organized?
24LC024H-I/SN stores 2 Kbits (256 bytes) of data organized as a single 32-page array with 8 bytes per page. Page-write operations allow writing up to 8 bytes in a single I2C transaction, reducing the time to program the full 256-byte array to approximately 32 write cycles at a 5 ms typical write cycle time.
What I2C clock frequency and supply range does 24LC024H-I/SN support?
24LC024H-I/SN supports I2C clock frequencies up to 1 MHz in fast-mode plus, and operates from 1.7 V to 5.5 V supply. The wide supply range covers 1.8 V ARM Cortex-M0 systems through 5 V AVR microcontroller designs, eliminating the need for an external level-shifter IC and saving 1-2 components in the BOM.
How many 24LC024H-I/SN devices can share a single I2C bus in a multi-sensor node design?
24LC024H-I/SN provides 2 hardware address pins (A1, A0) that set the lower 2 bits of the 1010DDDR I2C control byte, allowing up to 4 devices on one bus. In a 4-node industrial sensor array each storing 256 bytes of calibration data, all 4 EEPROMs share the same 2-wire I2C bus with total communication overhead under 50 µs per read transaction at 1 MHz.
What write endurance and data retention specs make 24LC024H-I/SN suitable for a product with a 10-year service life?
24LC024H-I/SN is rated for 1,000,000 write/erase cycles per byte and 200-year data retention at 25°C. For a product updating its configuration once per day over a 10-year service life, total write count reaches approximately 3,650 cycles — well under the 1,000,000 cycle rating, providing a 274× endurance margin. The 200-year retention also means stored calibration data remains intact without battery backup.
