Frequently Asked Questions
What is the storage capacity and maximum I2C clock speed of the 24LC128T-I/MS?
The 24LC128T-I/MS provides 128Kbit of non-volatile EEPROM storage accessible via I2C at up to 400kHz in fast-mode operation. This combination enables rapid read and write transactions for configuration and calibration data in microcontroller-based designs.
How many write cycles and how long can the 24LC128T-I/MS retain stored data?
The 24LC128T-I/MS is rated for at least 1 million write/erase cycles and guarantees a minimum data retention time of 200 years under standard storage conditions. This makes it suitable for applications with frequent configuration updates such as industrial parameter logging and firmware configuration storage.
How many 24LC128T-I/MS devices can be connected on a single I2C bus and how is addressing configured?
Up to 8 devices with address code 1010DDDR can share a single 2-wire I2C bus by configuring the 3 address pins (A0, A1, A2) uniquely per device. This allows up to 1Mbit of total non-volatile storage on a single I2C bus without additional interface hardware.
What lead time should designers plan for when procuring the 24LC128T-I/MS in volume?
The 24LC128T-I/MS has a factory lead time of approximately 13 weeks in MSOP-8 package. Design teams should initiate procurement early during prototype-to-production transition and consider maintaining 6 to 8 weeks of safety stock to avoid supply disruptions during production ramp-up.
