Frequently Asked Questions
How many write/erase cycles does the 24LC65-I/P support, and what is its data retention rating?
The 24LC65-I/P guarantees 100,000 write/erase cycles and provides data retention exceeding 200 years under normal operating conditions, making it suitable for applications that require frequent configuration updates as well as long-term archival storage.
At what maximum clock frequency can the 24LC65-I/P communicate over I2C?
The 24LC65-I/P supports I2C clock frequencies up to 100 kHz in standard mode. This 8-pin PDIP device operates from a 2.5 V to 5.5 V supply and uses the 7-bit address scheme 1010DDDR, allowing up to 8 devices on a single bus.
Which applications benefit most from using the 24LC65-I/P instead of a larger EEPROM?
Applications that require 64 Kbits (8K x 8 bytes) of non-volatile storage, such as storing device calibration tables, serial numbers, and small firmware patches, benefit from the 24LC65-I/P. Its -40°C to +85°C industrial temperature range also suits field-deployed equipment like smart meters and HVAC controllers.
