24AA08T-I/MS

Memory IC Overview

The Microchip Technology 24AA08T-I/MS is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz when VCC is between 2.5V and 5.5V, or 100 kHz when VCC is between 1.7V and 2.5V. It utilizes low-power CMOS technology with maximum standby current of 1 µA and read current of 1 mA. The component includes hardware write-protect functionality via the WP pin and offers data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol
• Includes hardware write-protect capability for memory security
• Features Schmitt trigger inputs for noise suppression
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Data logging in industrial environments
• Configuration storage for embedded systems
• Parameter storage in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the 'MS' suffix indicates the 8-Lead MSOP package type. Ensure the 'T' suffix matches the required tape and reel packaging format rather than tube or cut tape. Cross-reference the specific revision level in the datasheet to confirm compatibility with your system requirements.

Memory IC Selection Notes

Select this part if your design requires operation down to 1.7V, as the 24LC08B variant requires a minimum of 2.5V. Choose this component over the 24FC08 if a lower maximum clock frequency of 400 kHz is acceptable, as the 24FC08 supports 1 MHz. Verify that the 8-MSOP package dimensions fit your PCB layout constraints compared to other available packages like SOIC or TSSOP.

Memory IC Part Context

This component belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24LC08B and 24FC08 devices but differs in operating voltage ranges and maximum clock speeds. The 24AA08 series is specifically designed for applications requiring low-voltage operation starting at 1.7V, distinguishing it from the standard 2.5V minimum requirement of the 24LC08B.

Memory IC Replacement Considerations

The 24LC08BT-I/MS serves as a functional substitute within the same package, though it requires a minimum supply voltage of 2.5V instead of 1.7V. The 24AA08T-I/SN is an alternative in the SOIC-8 package. Ensure voltage thresholds and clock speed limitations are evaluated before substituting.
