24AA00-I/P

Memory IC Overview

The Microchip Technology 24AA00-I/P is a 128-bit (16 x 8) Electrically Erasable PROM featuring a 2-wire I2C serial interface. It operates on a single supply voltage ranging from 1.8V to 5.5V with typical active current of 500 µA and standby current of 1 µA. The device supports clock frequencies up to 400 kHz, offers data retention exceeding 200 years, and withstands over one million erase/write cycles. It includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.8V with minimal active and standby currents
• I2C compatible 2-wire serial interface with Schmitt trigger inputs for enhanced noise suppression
• Self-timed erase/write cycle with acknowledge polling capability to maximize bus throughput
• High reliability characterized by over one million write cycles and extended data retention

Memory IC Applications

• Storage of calibration values in electronic systems
• Retention of unique ID numbers for device identification
• Recording manufacturing information during production processes

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range of -40°C to +85°C. Confirm the '/P' designation indicates an 8-lead PDIP package. Ensure the source documentation explicitly lists this part number as active or available for order, as availability status can change without notice. Cross-reference the datasheet revision to ensure compatibility with current design requirements.

Memory IC Selection Notes

Select this component when a small amount of non-volatile memory is required for storing configuration data or identifiers. The 1.8V minimum operating voltage makes it suitable for low-voltage applications where other EEPROMs requiring higher voltages are unsuitable. The I2C interface simplifies connectivity with microcontrollers that support standard two-wire protocols.

Memory IC Part Context

This device belongs to the 24AA00/24LC00/24C00 family of 128-bit serial EEPROMs. While sharing similar functional characteristics, the 24AA00 variant is distinguished by its ability to operate at lower supply voltages starting at 1.8V, compared to the 2.5V minimum for the 24LC00 and 4.5V for the 24C00. All variants utilize the same pinout and I2C protocol.

Memory IC Replacement Considerations

The 24LC00-I/P is a direct functional substitute within the same package, though it requires a minimum supply voltage of 2.5V instead of 1.8V. Designers must verify that their system's VCC rail remains above 2.5V to ensure reliable operation if substituting this part.
