24AA02T-I/OT16KVAO

Memory IC Overview

The Microchip Technology 24AA02T-I/OT16KVAO is a 2-Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V, with a maximum clock frequency of 400 kHz at voltages above 2.5V and 100 kHz below that threshold. The device features a maximum active read current of 1 mA and standby current of 1 µA. It supports page writes of up to 8 bytes with a maximum cycle time of 5 ms. The component is housed in a 5-lead SOT-23 package and is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional data transmission via a standard two-wire serial bus protocol compatible with I²C.
• Includes hardware write protection controlled by the WP pin to inhibit memory writes when tied to VCC.
• Features Schmitt trigger inputs and noise suppression filters to ensure reliable operation on noisy buses.
• Provides output slope control mechanisms designed to eliminate ground bounce during switching.

Memory IC Applications

• Non-volatile data storage for system configuration parameters
• Calibration value retention in embedded sensors
• Device identification and serial number storage

Memory IC Procurement Notes

Verify the specific ordering suffix '16KVAO' against official Microchip documentation to confirm packaging and qualification details. Standard datasheets list 'I/OT' as Industrial temperature SOT-23. Confirm if '16KVAO' denotes a specific automotive or volume packaging variant requiring AEC-Q100 validation. Request manufacturer confirmation for lead times and availability prior to finalizing procurement plans.

Memory IC Selection Notes

Select this component for applications requiring low-power non-volatile memory with minimal pin count. Ensure the operating voltage remains within the 1.7V to 5.5V range to maintain the specified 400 kHz clock speed. Verify that the host controller supports the required I²C start/stop conditions and acknowledge polling. Consider the 8-byte page buffer size when designing write algorithms to optimize bus throughput.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs, which also includes the 24LC02B and 24FC02 variants. While sharing similar memory architecture and interface protocols, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24AA02 specifically supports operation down to 1.7V, distinguishing it from the 2.5V minimum requirement of the 24LC02B.

Memory IC Replacement Considerations

Direct replacements include other 24AA02 variants in different packages such as 24AA02-I/SN or 24AA02-I/MC. Cross-family substitutes like 24LC02B require verification of the 2.5V minimum voltage constraint. Ensure any replacement maintains the 5-lead SOT-23 footprint or utilizes an adapter if pin compatibility differs.
