Frequently Asked Questions
What is the memory density and organization of the 24LC128-I/SM?
The 24LC128-I/SM provides 128Kbits of EEPROM organized as 16,384 bytes (16K x 8), allowing storage of substantial configuration data, lookup tables, or calibration coefficients in a single compact IC.
What is the maximum I2C clock frequency supported by the 24LC128-I/SM?
The device supports the I2C fast mode with a maximum clock frequency of 400kHz (0.4MHz), enabling faster data transfers compared to standard 100kHz mode and reducing bus transaction latency.
How many devices can share one I2C bus with the 24LC128-I/SM?
Up to eight 24LC128 devices can coexist on a single I2C bus by configuring the three hardware address pins (A0, A1, A2), allowing up to 1Mbit of total EEPROM capacity without additional bus components.
What is the write endurance and data retention of the 24LC128-I/SM?
The 24LC128-I/SM guarantees a minimum endurance of 1,000,000 write/erase cycles per byte and a data retention of at least 200 years, making it suitable for applications with frequent data updates and long product lifetimes.
Is the 24LC128-I/SM available in a lead-free package?
Yes, the 24LC128-I/SM carries JESD-609 code e3, confirming it is manufactured with a lead-free (Pb-free) process and is fully RoHS compliant for use in environmentally regulated markets worldwide.
