Frequently Asked Questions
What is the memory capacity and organization of the 24LC64T-I/OT?
The 24LC64T-I/OT provides 64Kbit of memory organized as 8,192 bytes (8Kx8). This capacity is ideal for storing firmware configuration data, calibration constants, serial numbers, and user settings in embedded microcontroller applications requiring compact non-volatile storage.
What interface and clock speed does the 24LC64T-I/OT support?
The 24LC64T-I/OT uses the I2C (two-wire) serial interface with a maximum clock frequency of 400 kHz (Fast Mode). The I2C control byte is 1010XXXR, allowing up to 8 devices to be addressed on the same bus using the three address pins, enabling flexible multi-device memory expansion.
How reliable is the 24LC64T-I/OT in terms of endurance and data retention?
The 24LC64T-I/OT is rated for 1,000,000 write/erase cycles with a minimum data retention of 200 years. These specifications exceed those of many competing EEPROMs, making it suitable for applications requiring frequent data updates, such as industrial data loggers, energy meters, and configuration storage in embedded systems.
What package does the 24LC64T-I/OT use?
The 24LC64T-I/OT is housed in an SOT-23-5 (5-pin Small Outline Transistor) package, one of the smallest surface-mount IC packages available. This makes it ideal for compact PCB designs in wearables, handheld instruments, and IoT sensor nodes where board space is at a premium.
Is the 24LC64T-I/OT suitable for industrial applications?
Yes, the 24LC64T-I/OT is designated with an 'I' suffix indicating an industrial temperature range, making it suitable for operation in demanding environments.
