Frequently Asked Questions
What is the storage capacity of the 24AA512-I/SM?
The 24AA512-I/SM provides 512Kbit (64KB) of EEPROM storage organized as 65,536 x 8 bits, offering sufficient capacity for firmware configuration tables, event logs, calibration data, and user settings in embedded applications.
What I2C bus speed does the 24AA512-I/SM support?
The 24AA512-I/SM supports standard mode (100 kHz) and Fast Mode (400 kHz) I2C operation. The I2C control byte is 1010DDDx, where the D bits are hardware-selectable device address pins enabling up to eight devices on one bus.
How many write cycles does the 24AA512-I/SM support and how long is data retained?
The 24AA512-I/SM guarantees 1,000,000 write/erase cycles per page location, combined with a minimum 200-year data retention time, ensuring robust and long-lasting non-volatile storage for mission-critical embedded systems.
Does the 24AA512-I/SM have write protection?
Yes, the 24AA512-I/SM includes a hardware write-protect (WP) pin that, when asserted, prevents all write operations to the entire memory array, protecting stored data from accidental writes during normal system operation.
What package is used for the 24AA512-I/SM?
The 24AA512-I/SM uses an 8-pin SOIJ package (JEDEC R-PDSO-G8), which features J-bend gull-wing leads compatible with standard SOIC-8 PCB footprints, enabling easy automated surface-mount assembly.
