24AA08-I/MS

Memory IC Overview

The Microchip Technology 24AA08-I/MS is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 1.7V to 5.5V and features a two-wire serial interface compatible with I²C™ standards. The device supports clock frequencies up to 400 kHz at voltages above 2.5V, or 100 kHz when operating between 1.7V and 2.5V. It includes hardware write protection via the WP pin and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Low-voltage CMOS technology enabling operation down to 1.7V with minimal standby and active currents.
• I²C-compatible bidirectional two-wire serial interface with Schmitt trigger inputs for noise suppression.
• Hardware write-protect capability that inhibits all write operations across the entire memory array when the WP pin is tied high.
• Self-timed erase/write cycle with a page write buffer allowing sequential storage of up to 16 bytes.

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I²C bus communication

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the 'MS' designation corresponds to the 8-lead MSOP package. Ensure the source documentation explicitly lists the 24AA08 variant rather than the 24LC08B or 24FC08, as voltage ranges and clock speeds differ between these series members.

Memory IC Selection Notes

Select this component for designs requiring robust data retention and high endurance in space-constrained surface-mount applications. The 24AA08-I/MS is suitable for systems operating at lower supply voltages compared to standard 5V logic families. Consider the 16-byte page write buffer for efficient data handling in sequential write scenarios.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features but varies in voltage specifications and maximum clock frequencies depending on the specific model prefix (AA, LC, or FC). The 24AA08 is optimized for wide voltage operation starting at 1.7V.
