Frequently Asked Questions

How much data can the 24CS512T-I/MS store and how fast can it be accessed?

The 24CS512T-I/MS provides 512 Kbit (64 KB) of non-volatile storage accessible over an I2C bus at up to 3.4 MHz in Fast-mode Plus, enabling rapid read and write cycles in data-intensive embedded applications.

For how many write cycles is the 24CS512T-I/MS rated before wear-out?

The device is rated for a minimum of 1,000,000 write/erase cycles per byte location, with a data retention time of at least 200 years, making it reliable for frequent-update logging or configuration storage in industrial systems.

Which supply voltage range does the 24CS512T-I/MS support, and how does this affect system design?

The 24CS512T-I/MS operates from 1.7 V to 5.5 V, allowing direct connection to both 3.3 V and 5 V microcontrollers without level-shifting circuitry, simplifying BOM and reducing design complexity in mixed-voltage systems.

When would a designer choose the 24CS512T-I/MS over a larger EEPROM such as 24CS1025?

The 24CS512T-I/MS is preferred when 64 KB capacity is sufficient, as it costs less and occupies the same 8-pin MSOP footprint, avoiding over-provisioning while still delivering 3.4 MHz I2C speed and 1,000,000 cycle endurance.
