24AA32AFT-I/MS

Memory IC Overview

The Microchip Technology 24AA32AFT-I/MS is a 32 Kbit Electrically Erasable PROM organized as a single block of 4K x 8-bit memory. It operates with a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 400 kHz on its I²C compatible 2-wire serial interface. The device features an access time of 900 ns at VCC ≥ 2.5V, a page write buffer for up to 32 bytes, and hardware write-protect capability for the upper quarter of the array. It is housed in an 8-lead MSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.7V with minimal standby and active currents.
• I²C compatible 2-wire serial interface supporting 100 kHz and 400 kHz clock frequencies.
• Hardware write-protect pin allows inhibition of write operations for the upper quarter of the memory array.
• Schmitt trigger inputs provide noise suppression while output slope control eliminates ground bounce.

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage.
• Data acquisition systems needing reliable parameter retention.
• Industrial applications utilizing I²C bus communication protocols.

Memory IC Procurement Notes

Verify that the specific suffix 'FT' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the 'I' designation aligns with the specified industrial temperature range requirements for your operational environment. Ensure compatibility with the 8-lead MSOP footprint during PCB layout verification.

Memory IC Selection Notes

Select this component when a 32 Kbit EEPROM capacity is required alongside strict low-voltage operation capabilities starting at 1.7V. The MSOP package offers a compact surface-mount solution suitable for space-constrained designs. Consider the hardware write-protect feature if protecting critical configuration data in the upper memory regions is necessary for system integrity.

Memory IC Part Context

This part belongs to the 24AA32AF series of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC32AF variant but differs in minimum operating voltage specifications. The series provides a standardized I²C interface for easy integration into existing embedded systems requiring non-volatile data storage.

Memory IC Replacement Considerations

The 24AA32AT-I/MS is a documented substitute within the same product family, offering identical electrical characteristics and pinout compatibility.
