24AA01T-I/LT

Memory IC Overview

The Microchip Technology 24AA01T-I/LT is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes low-power CMOS technology, drawing a maximum standby current of 1 µA and an active read current of 1 mA. It supports page writes of up to 8 bytes with a maximum write cycle time of 5 ms. The component is housed in a 5-lead SC-70 package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Low-voltage design enabling operation down to 1.7V with minimal power consumption
• Integrated hardware write-protect capability via the WP pin
• Schmitt trigger inputs and noise filtering for reliable data transmission on noisy buses
• Self-timed erase/write cycles with automatic acknowledge polling support

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communication devices needing low-power memory
• Industrial control applications with strict environmental constraints

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage range requirements align with the 1.7V minimum specification for the 24AA01 series. Ensure compatibility with the host controller's I2C bus timing parameters before finalizing procurement.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small capacity non-volatile storage. The SC-70 package offers space efficiency compared to standard SOIC or PDIP options. Consider the 1.7V operating limit if designing for ultra-low voltage environments where other EEPROMs may require higher voltages.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24LC01B and 24FC01, which share similar interfaces but differ in voltage ranges and clock speeds. The 24AA01 variant specifically supports the lower 1.7V operating threshold.

Memory IC Replacement Considerations

The 24LC01B serves as a functional substitute within the same family, though it requires a minimum supply voltage of 2.5V rather than 1.7V. Verify that the application circuit can accommodate the higher voltage requirement if substituting.
