24AA16T-I/ST

Memory IC Overview

The Microchip Technology 24AA16T-I/ST is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 1.7V to 5.5V and supports I2C compatible two-wire serial interface communication. The device features a maximum clock frequency of 400 kHz at voltages above 2.5V, reducing to 100 kHz below 2.5V. It includes a 16-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression. The component is available in an 8-lead TSSOP package and meets Industrial temperature specifications.

Memory IC Feature Summary

• Supports low-voltage operation down to 1.7V with minimal standby current consumption
• Includes a 16-byte page write buffer to enhance data transfer efficiency
• Features hardware write protection controlled by the dedicated WP pin
• Incorporates Schmitt trigger inputs and filter circuits for improved noise immunity

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices needing compact memory solutions
• Industrial control applications operating within specified temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'ST' indicates the TSSOP package. Confirm the specific revision level matches the design requirements. Ensure the system voltage remains within the 1.7V to 5.5V operational limits to maintain performance specifications.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity is required with I2C interface compatibility. It is suitable for designs needing hardware write protection and low power consumption. Consider the 400 kHz clock speed limit at higher voltages and the reduced speed at lower voltages when designing the bus timing.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs, which also includes the 24LC16B and 24FC16 variants. While sharing similar memory organization and interface protocols, differences exist in minimum operating voltage and maximum clock frequency among the family members.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA16 without the tape-and-reel suffix or other package variations like the SOIC version. Cross-family replacements such as the 24LC16B require verification of the minimum supply voltage compatibility.
