24LC32A-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC32A-E/SN16KVAO is a 32-Kbit (4K x 8) serial EEPROM utilizing an I2C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V with a maximum clock frequency of 400 kHz and a typical access time of 900 ns. The device features a 32-byte page write buffer, hardware write protection via the WP pin, and supports up to eight devices on a single bus. It is qualified under AEC-Q100 standards for automotive applications and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Hardware write-protect capability via dedicated control pin
• Integrated 32-byte page write buffer for efficient data handling
• Schmitt trigger inputs designed for enhanced noise suppression

Memory IC Applications

• Automotive electronic systems requiring durable non-volatile storage
• Industrial equipment needing reliable parameter logging
• Consumer electronics storing configuration settings
• IoT devices managing low-power operational data

Memory IC Procurement Notes

Verify that the specific suffix '16KVAO' corresponds to the required automotive qualification and packaging specifications. Confirm compatibility with the target system's I2C bus voltage levels and address pin configurations. Ensure the extended temperature range meets environmental requirements. Cross-reference the datasheet revision to confirm current manufacturing status and any potential obsolescence notices.

Memory IC Selection Notes

Select this component when automotive certification is mandatory for memory applications. Choose this part for designs requiring robust write protection and high endurance in harsh environments. Consider this option if the system architecture benefits from the specific 8-lead SOIC package dimensions. Evaluate against standard industrial variants only if automotive qualification is not strictly required by the final product specification.

Memory IC Part Context

This device belongs to the 24LC32A family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other members of the series but is distinguished by its specific automotive qualification and extended temperature rating. The 'SN' designation indicates an 8-lead Small Outline Integrated Circuit package, while the 'E' suffix denotes the extended temperature operating range.

Memory IC Replacement Considerations

Direct substitutes include other AEC-Q100 qualified 32Kbit I2C EEPROMs from Microchip such as the 24AA32A series or equivalent parts from other manufacturers meeting identical voltage and interface specifications. Verify pinout compatibility and electrical characteristics before substitution.
