24AA08T-I/SN

Memory IC Overview

The Microchip Technology 24AA08T-I/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 and supports clock frequencies up to 400 kHz at voltages above 2.5V, or 100 kHz below that threshold. It utilizes low-power CMOS technology with maximum standby current of 1 µA and active read current of 1 mA. The component includes hardware write protection via the WP pin and offers data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol for efficient bus utilization
• Includes hardware write-protect capability to secure memory arrays against unauthorized modifications
• Integrates Schmitt trigger inputs and noise filtering circuits to ensure signal integrity in noisy environments
• Features self-timed erase/write cycles with automatic page buffer management for streamlined data operations

Memory IC Applications

• Data logging systems requiring non-volatile storage for sensor readings
• Configuration parameter storage in embedded controllers
• Calibration data retention for industrial instrumentation
• Device identification and serial number storage in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms Industrial temperature range operation (-40°C to +85°C). Confirm 'SN' indicates the 8-Lead SOIC package type. Ensure the 'T' suffix matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the datasheet revision to confirm compatibility with your system's voltage levels and interface timing requirements.

Memory IC Selection Notes

Select this component when low-voltage operation down to 1.7V is required alongside standard I²C compatibility. Consider the 16-byte page write buffer for applications needing moderate throughput without complex controller logic. Evaluate the hardware write-protect feature if physical security of stored data is critical. Compare against the 24LC08B variant if the system strictly operates above 2.5V and requires extended temperature options.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs, which shares architectural similarities with the 24LC08B and 24FC08 devices. While the 24LC08B requires a minimum 2.5V supply and the 24FC08 supports higher 1 MHz speeds, the 24AA08 provides a balanced solution for general-purpose low-voltage applications. The family standardizes the I²C interface and memory organization across different performance tiers.

Memory IC Replacement Considerations

The 24AA08-I/SN serves as a direct functional substitute for other 24AA08 variants in the SOIC-8 package, such as the 24AA08-SN, provided temperature grades align. Verify that any replacement maintains the same 1.7V-5.5V operating range and 400 kHz clock speed limitations.
