Frequently Asked Questions
What storage capacity and page write size does the 24LC08B/P provide for embedded data logging?
The 24LC08B/P provides 8 Kbit (1024 bytes) of I2C EEPROM storage with a 16-byte page write buffer. This capacity is well-suited for storing configuration tables, sensor calibration data, and small event logs in embedded systems operating from 2.5V to 5.5V supply rails.
How does the 24LC08B/P endurance compare to flash-based storage for write-intensive industrial sensor applications?
The 24LC08B/P guarantees 1,000,000 write/erase cycles per byte and a minimum 200-year data retention, which is significantly higher endurance than many parallel flash devices for byte-level writes. This makes it preferable for industrial sensor nodes that update small configuration or calibration registers thousands of times over a product lifetime.
Can the 24LC08B/P operate in a 3.3V microcontroller system, and what I2C clock rate does it support?
Yes, the 24LC08B/P operates across a 2.5V to 5.5V supply range, covering both 3.3V and 5V microcontroller systems. It supports a maximum I2C clock frequency of 400 kHz (Fast Mode), allowing efficient data transfers when reading or writing across its 8 Kbit address space via the I2C control byte 1010XMMR.
What is the factory lead time for the 24LC08B/P, and is it RoHS compliant?
The 24LC08B/P has a factory lead time of 8 weeks and carries a Pb-free (RoHS compliant) designation with a JESD-609 e3 rating. It is available in an 8-pin PDIP through-hole package, making it straightforward to source for both prototyping runs and volume production across global supply chains.
