24AA16H-I/P

Memory IC Overview

The Microchip Technology 24AA16H-I/P is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates on a single supply ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz at voltages above 2.5V, and 100 kHz below 2.5V. The device features a 16-byte page write buffer, hardware write-protect for the upper half-array (addresses 400h-7FFh), and Schmitt trigger inputs for noise suppression. It supports industrial temperature ranges from -40°C to +85°C and is housed in an 8-Lead PDIP package.

Memory IC Feature Summary

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

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• IoT devices utilizing low-voltage operation
• Automotive applications meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'P' indicates the 8-Lead PDIP package. Confirm the specific voltage requirements align with the 1.7V to 5.5V operational range. Ensure compatibility with the I2C interface protocol before integration into existing designs.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is required with hardware write-protection for critical data segments. The 24AA16H variant is suitable for applications operating down to 1.7V, unlike the 24LC16BH which requires a minimum of 2.5V. Consider the PDIP package only if through-hole mounting is necessary for the specific PCB layout constraints.

Memory IC Part Context

This part belongs to the 24XX16H family, which includes variants like the 24LC16BH and 24FC16H. While sharing the same core architecture and 16-Kbit capacity, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24AA16H specifically targets low-voltage industrial environments.

Memory IC Replacement Considerations

Direct substitutes include other 24AA16H variants with different packages such as 24AA16H-I/SN or 24AA16H-I/MS. Cross-family replacements like the 24LC16H require verification of the minimum supply voltage compatibility.
