24AA01T-I/OT16KVAO

Memory IC Overview

The Microchip Technology 24AA01T-I/OT16KVAO is a 1 Kbit Electrically Erasable PROM (EEPROM) organized as one block of 128 x 8-bit memory. It features a 2-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 400 kHz at VCC levels between 2.5V and 5.5V, or 100 kHz when operating below 2.5V. The device operates on a single supply voltage ranging from 1.7V to 5.5V. It includes an 8-byte page write buffer, hardware write-protect capabilities via the WP pin, and Schmitt trigger inputs for noise suppression. The component is qualified for automotive applications under AEC-Q100 standards.

Memory IC Feature Summary

• Supports bidirectional data transmission over a 2-wire serial bus using standard I2C protocol.
• Includes an 8-byte page write buffer to optimize write operations within physical page boundaries.
• Features hardware write protection that inhibits all memory writes when the WP pin is tied to VCC.
• Incorporates Schmitt trigger inputs and filter circuits to suppress noise spikes on the SCL and SDA lines.

Memory IC Applications

• Automotive electronic systems requiring AEC-Q100 qualified non-volatile storage
• Industrial control devices needing low-power data retention
• Consumer electronics utilizing I2C-based configuration storage

Memory IC Procurement Notes

Verify the specific suffix '16KVAO' against official Microchip documentation to confirm if it denotes a specific tape-and-reel quantity, lead-free status, or automotive grade variant distinct from the standard datasheet listing. Ensure the ordering code matches the required package type and temperature range specifications before finalizing procurement.

Memory IC Selection Notes

Select this component for designs requiring a compact 1 Kbit EEPROM solution with I2C compatibility. It is suitable for applications demanding operation down to 1.7V and robust noise immunity through Schmitt triggers. Consider the 8-byte page buffer size when designing write algorithms to prevent data rollover across page boundaries.

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 differ primarily in minimum operating voltage and maximum clock frequency. The 24AA01 series specifically supports operation down to 1.7V, making it distinct from the 2.5V minimum requirement of the 24LC01B.

Memory IC Replacement Considerations

Direct substitutes include other parts within the 24AA01 family such as 24AA01T-I/OT or 24AA01-I/SN, provided the package and temperature grades match. Cross-family replacements like the 24LC01B require verification of the minimum supply voltage constraints.
