24AA16HT-I/MS

Memory IC Overview

The Microchip Technology 24AA16HT-I/MS is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. 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 lower voltages. The device features a 16-byte page write buffer, hardware write-protect for the upper half-array (400h-7FFh), and Schmitt trigger inputs for noise suppression. It supports I2C compatible two-wire serial interface protocols.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Low-power CMOS technology with standby current as low as 1 μA
• Integrated 16-byte page write buffer for efficient data transfer
• Schmitt trigger inputs and output slope control for enhanced noise immunity

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices with low power constraints
• Industrial control applications needing hardware write protection
• Embedded systems utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) and 'MS' specifies the 8-Lead MSOP package. Confirm the 'T' indicates tape and reel packaging if applicable to your specific sub-part number variant. Ensure compatibility with 1.7V to 5.5V supply rails before integration.

Memory IC Selection Notes

Select this component when a 16-Kbit EEPROM with hardware write-protect functionality is required. It is suitable for designs operating down to 1.7V, unlike the 24LC16BH which requires 2.5V minimum. Choose this over the 24FC16H if 400 kHz speed is sufficient and cost or availability favors the AA series.

Memory IC Part Context

This part belongs to the 24XX16H family, which includes the 24AA16H, 24LC16BH, and 24FC16H variants. These devices share similar physical layouts and I2C interfaces but differ in minimum operating voltage and maximum clock frequency specifications based on the manufacturer's technology node.

Memory IC Replacement Considerations

Direct substitutes within the same family include 24AA16H-I/MS (same specs, different packaging suffix potentially). Cross-family replacements like 24AA16-I/MS lack the half-array write-protect feature.
