Frequently Asked Questions
How much data can the 24LC1025-I/P hold, and how does write endurance affect long-term deployment?
The 24LC1025-I/P stores 1 Mbit (128,000 bytes) of data. With a write endurance of 1,000,000 cycles per byte location and a minimum data retention of 200 years, it suits applications that update settings infrequently, such as calibration records in industrial instruments or configuration storage in smart meters.
At what I2C clock speed does the 24LC1025-I/P operate, and does it support fast-mode I2C controllers?
The 24LC1025-I/P supports a maximum I2C clock frequency of 1 MHz, which is compatible with standard-mode (100 kHz) and fast-mode (400 kHz) I2C controllers. Many microcontrollers running fast-mode plus at 1 MHz can also interface directly, enabling faster bulk reads of the 128 KB address space.
Is the 24LC1025-I/P suitable for a 3.3 V microcontroller design, and what package options aid prototyping?
Yes. The 24LC1025-I/P operates from 2.5 V to 5.5 V, so it is fully compatible with 3.3 V microcontroller systems. The 8-pin PDIP package simplifies breadboard and through-hole prototyping, while the JESD-609 e3 compliance indicates RoHS-compliant, lead-free construction for production use.
