What are the key features of 24LC1024-E/SN?
- 1 Mbit (128K x 8) I2C serial EEPROM with 400 kHz and 1 MHz bus speed modes
- Wide supply voltage range of 2.5 V to 5.5 V suits 3.3 V and 5 V systems
- 256-byte page write buffer reduces write cycles; 1 million erase/write cycle endurance
- Hardware write-protect pin for full array protection
What is 24LC1024-E/SN used for?
The 24LC1024-E/SN is used to store calibration data, configuration parameters, and firmware images in industrial controllers, smart meters, and medical devices. Its I2C interface and wide voltage range make it a natural fit for microcontroller-based designs where non-volatile byte-addressable storage up to 128 KB is required. The device is also deployed in automotive infotainment modules and IoT edge nodes that need reliable data retention beyond 200 years at 25°C.

Frequently Asked Questions
What is the maximum clock frequency supported by the 24LC1024-E/SN?
The 24LC1024-E/SN supports a maximum I2C clock frequency of 1 MHz in Fast-Mode Plus operation, and is backward compatible with 100 kHz standard-mode and 400 kHz fast-mode buses. This makes it usable across a wide range of microcontrollers without changing firmware.
How much data can be written in a single page write operation on the 24LC1024-E/SN?
A single page write operation can buffer up to 256 bytes at once, which reduces the number of write cycles needed for large data blocks. The device guarantees at least 1 million erase/write cycles per page and retains data for more than 200 years at 25°C.
Can the 24LC1024-E/SN operate in a 3.3 V microcontroller design?
Yes. The 24LC1024-E/SN operates over a supply range of 2.5 V to 5.5 V, making it fully compatible with 3.3 V systems. The device draws a maximum active current of 3 mA during write operations and as little as 1 µA in standby, which suits battery-powered IoT designs.
When would a designer choose 24LC1024-E/SN over a smaller 24LC512 device?
A designer would choose the 24LC1024-E/SN when the application requires 1 Mbit (128 KB) of non-volatile storage rather than 512 Kbit (64 KB). Both devices share the same SOIC-8 footprint and I2C protocol, so migration requires only a one-bit address change with no PCB redesign. Typical upgrade scenarios include firmware image backup storage and large lookup tables in industrial sensors.
