Frequently Asked Questions
What is the memory capacity of the 24FC515-I/SM?
The 24FC515-I/SM provides 512Kbit (64KB) of EEPROM storage. This relatively large capacity for a serial EEPROM allows it to hold substantial configuration tables, event logs, calibration datasets, or firmware parameter blocks in embedded systems where internal microcontroller flash is insufficient or unsuitable for frequent rewriting.
What interface does the 24FC515-I/SM use and how fast is it?
The 24FC515-I/SM uses the standard I2C (two-wire) serial interface with an I2C control byte of 1010MDDR, supporting clock frequencies up to 1MHz (Fast-mode Plus). The I2C bus allows multiple EEPROM devices and other peripherals to share the same two-wire bus, reducing wiring complexity in systems with multiple non-volatile storage nodes.
How many write cycles does the 24FC515-I/SM support?
The 24FC515-I/SM is rated for 1 million write/erase cycles per memory cell. Combined with its 200-year data retention specification, this endurance makes the device suitable for applications where configuration parameters or event logs are updated frequently, such as industrial metering, data acquisition, and smart infrastructure endpoints.
What package does the 24FC515-I/SM use?
The 24FC515-I/SM comes in an SOIJ-8 (Small Outline Integrated Circuit, J-lead, 8-pin) surface-mount package with a 5.28mm body width. This RoHS-compliant package is compatible with standard SMT assembly processes, and the J-lead style provides reliable solder joints suitable for applications requiring mechanical robustness against vibration or thermal cycling.
What are typical applications for the 24FC515-I/SM?
The 24FC515-I/SM is commonly used in industrial automation, smart metering, networking equipment, medical devices, and consumer appliances requiring large-capacity non-volatile data storage. Its I2C bus sharing capability, high endurance, and 512Kbit capacity make it an excellent choice for event loggers, firmware parameter stores, calibration coefficient tables, and configuration data repositories in multi-node embedded systems.
