24AA16H-I/ST

Memory IC Overview

The Microchip Technology 24AA16H-I/ST is a 16-Kbit (2K x 8) Electrically Erasable PROM featuring an I²C-compatible two-wire serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz at VCC ≥ 2.5V, and 100 kHz at VCC < 2.5V. The device includes hardware write-protect functionality for the upper half-array (addresses 400h-7FFh) via the WP pin. It supports page writes of up to 16 bytes and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array
• Low-power CMOS technology with standby current as low as 1 μA
• Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data logging in industrial environments
• Configuration storage in consumer electronics
• Parameter storage in automotive systems

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the 'ST' suffix indicates the 8-Lead TSSOP package. Ensure the specific part number matches the required voltage and speed specifications for your application design.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM with hardware write protection is required. It is suitable for applications needing operation down to 1.7V. Consider the 24LC16BH if a minimum 2.5V supply is mandatory, or the 24FC16H if 1 MHz operation is needed.

Memory IC Part Context

This device belongs to the 24XX16H family of 16-Kbit serial EEPROMs. It shares functional similarities with the 24LC16BH and 24FC16H but differs in minimum operating voltage and maximum clock frequency capabilities.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC16BH and 24FC16H, provided their respective voltage and speed constraints align with the system requirements.
