24AA16HT-I/MNY

Memory IC Overview

The Microchip Technology 24AA16HT-I/MNY is a 16-Kbit (2K x 8) Electrically Erasable PROM featuring a two-wire I²C 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 utilizes low-power CMOS technology, drawing a maximum active read current of 1 mA and standby current of 1 μA in industrial temperature ranges (-40°C to +85°C). It includes hardware write-protect capabilities for half the array and supports page writes up to 16 bytes.

Memory IC Feature Summary

• Hardware write-protect pin enables protection of the upper half of the memory array
• Schmitt trigger inputs provide noise suppression on SDA and SCL lines
• Output slope control minimizes ground bounce during switching
• Self-timed erase/write cycles with automatic termination

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Low-voltage embedded controllers
• Consumer electronics with I²C bus constraints
• Automotive applications meeting AEC-Q100 standards

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'I' designation matches required industrial temperature range specifications. Ensure the MNY package type aligns with PCB footprint requirements. Cross-reference the datasheet revision date against manufacturing lot codes for compliance verification.

Memory IC Selection Notes

Select this component when operating voltages drop below 2.5V, as other variants may require higher minimums. Consider the TDFN-8 package for space-constrained surface-mount designs. Evaluate the 100 kHz speed limitation at lower voltages against system timing requirements. Verify write-protection needs match the half-array hardware capability.

Memory IC Part Context

This part belongs to the 24XX16H family of 16-Kbit serial EEPROMs. It shares architectural similarities with the 24LC16BH and 24FC16H but differs in voltage thresholds and clock speeds. The 24AA16H variant specifically supports operation down to 1.7V, distinguishing it from the 2.5V minimum requirement of the LC series.

Memory IC Replacement Considerations

Direct substitutes include other 24AA16H variants with different packages such as 24AA16H-I/MS or 24AA16H-I/SN. For identical functionality in alternative packages, verify pin compatibility and electrical characteristics against the original datasheet specifications.
