Frequently Asked Questions
How is the 24LC08B-I/P memory organized and what page size does it support for burst writes?
The 24LC08B-I/P organizes its 8 kbit capacity as 4 blocks of 256 bytes, and supports 16-byte page writes in a single I2C transaction. This page-write capability speeds up bulk updates of configuration or calibration data stored in non-volatile memory.
What supply voltage range does the 24LC08B-I/P support and how does it aid mixed-voltage designs?
The device operates from 2.5 V to 5.5 V, covering both 3.3 V low-power microcontrollers and 5 V legacy systems without a level shifter in many cases. This wide range simplifies BOM and PCB layout in mixed-voltage designs such as industrial sensors or consumer appliances.
How long can the 24LC08B-I/P retain stored data and how many write cycles does it support?
The 24LC08B-I/P guarantees data retention greater than 40 years at room temperature, with endurance rated at 1,000,000 write/erase cycles minimum. This combination makes it suitable for applications that update EEPROM infrequently but demand extremely long product lifetimes.
For a prototype requiring through-hole assembly, why choose the 24LC08B-I/P DIP-8 package over an SMD variant?
The 8-pin PDIP package with 2.54 mm pitch allows direct insertion into breadboards and standard sockets, making it ideal for rapid prototyping and lab evaluation without SMD soldering tools. Once design is validated, the same I2C firmware works seamlessly if migrated to the SOT-23 or SOIC variant.
