24AA08T/SN

Memory IC Overview

The Microchip Technology 24AA08T/SN 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, supporting maximum clock frequencies of 400 kHz at voltages above 2.5V and 100 kHz below that threshold. It utilizes low-power CMOS technology with standby currents as low as 1 µA. The component is housed in an 8-lead SOIC package and supports industrial temperature ranges.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial bus protocol
• Includes hardware write-protect functionality controlled by the WP pin
• Features Schmitt trigger inputs for noise suppression on SDA and SCL lines
• Provides self-timed erase/write cycles with automatic termination

Memory IC Applications

• Data storage in battery-powered portable devices
• Configuration parameter retention in embedded systems
• Calibration data logging for sensor interfaces
• Device identification and tracking information storage

Memory IC Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-lead SOIC package variant when sourcing. Confirm the temperature grade matches the required operational environment, as industrial ratings differ from extended grades. Ensure the ordering code includes the correct tape and reel designation if automated surface-mount assembly is planned. Cross-reference the manufacturer datasheet revision to confirm pinout consistency with existing designs.

Memory IC Selection Notes

Select this component for applications requiring low-voltage operation down to 1.7V where power consumption is critical. The 8-Kbit capacity suits small data storage needs without excessive address complexity. Consider the 100 kHz limit at lower voltages when designing high-speed communication buses. The SOIC package offers standard footprint compatibility for general-purpose PCB layouts.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including page write capabilities and acknowledge polling functions. Variants within the series differ primarily in operating voltage ranges, maximum clock speeds, and available package types. The 24AA08 specifically targets low-voltage industrial applications.

Memory IC Replacement Considerations

Direct substitutes include other 24AA08 variants with different package suffixes such as ST or MC. Cross-family replacements like 24LC08B require verification of minimum voltage thresholds. Ensure any alternative maintains I2C compatibility and similar page buffer sizes for seamless integration.
