24AA00T/SN

Memory IC Overview

The Microchip Technology 24AA00T/SN is a 128-bit (16 x 8) serial EEPROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.8V to 5.5V. The device supports clock frequencies of 100 kHz and 400 kHz, with a typical access time of 3500 ns at the lower frequency range. It utilizes low-power CMOS technology, ensuring standby current remains below 1 µA. The component is housed in an 8-lead SOIC package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Low-voltage operation down to 1.8V with minimal power consumption
• I²C compatible bidirectional 2-wire serial data transfer
• Schmitt trigger inputs and noise filtering for signal integrity
• Self-timed erase/write cycles with acknowledge polling support

Memory IC Applications

• Storage of calibration values
• Identification number storage
• Manufacturing information recording

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-lead SOIC package variant. Confirm the temperature grade 'I' matches the required -40°C to +85°C operational range. Ensure the device version aligns with the 1.8V minimum supply requirement distinct from other family members. Cross-reference the datasheet revision to confirm pinout compatibility.

Memory IC Selection Notes

Select this part when a small memory capacity is sufficient for non-volatile data retention. It is suitable for systems requiring low active and standby currents. The 1.8V operating range makes it appropriate for battery-powered or low-voltage logic applications. Verify that the I²C bus speed requirements do not exceed the device's maximum clock frequency limits.

Memory IC Part Context

This component belongs to the 24AA00/24LC00/24C00 family of serial EEPROMs. While sharing the same interface and architecture, the 24AA00 is distinguished by its ability to operate at voltages as low as 1.8V, whereas other variants may require higher minimum supply levels. The 'T' suffix indicates tape and reel packaging, while 'SN' denotes the specific surface-mount package type.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC00T-I/SN and 24C00T-I/SN. Note that these alternatives may have different minimum supply voltage specifications compared to the 24AA00.
