24AA01HT-I/MS

Memory IC Overview

The Microchip Technology 24AA01HT-I/MS is a 1 Kbit Electrically Erasable PROM organized as 128 x 8-bit memory. It features a 2-Wire I2C compatible serial interface with a maximum clock frequency of 400 kHz and an access time of 900 ns. The device operates on a single supply voltage ranging from 1.7 V to 5.5 V, drawing a maximum active current of 3 mA and standby current of 1 μA. It supports page writes of up to 8 bytes and includes hardware write-protect for half the array. The component is housed in an MSOP-8 package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability inhibits write operations to the upper half of the memory array when the WP pin is tied high.
• Schmitt trigger inputs and output slope control provide noise suppression and eliminate ground bounce during operation.
• Supports acknowledge polling to maximize bus throughput by allowing the master to detect when internal write cycles are complete.

Memory IC Applications

• Low-power embedded systems requiring non-volatile data storage
• Industrial control applications operating in noisy environments
• Battery-powered devices utilizing low standby current modes

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design specifications align with the absolute maximum ratings to prevent permanent damage. Validate that the supply voltage remains within the operational limits defined in the datasheet electrical characteristics tables.

Memory IC Selection Notes

Select this component for designs requiring low-voltage operation down to 1.7 V and compact surface-mount packaging. The 24AA01HT variant specifically denotes the tape and reel packaging format suitable for automated assembly processes. Consider the hardware write-protect feature if partial memory security is required without software overhead. Verify compatibility with the system's I2C bus timing requirements at the target operating voltage.

Memory IC Part Context

This part belongs to the 24AA01H series of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The 'HT' suffix indicates the device is supplied in a tape and reel configuration for high-volume manufacturing. The 'I' designation specifies the industrial temperature rating. It shares functional similarities with the 24LC01BH series but differs in minimum operating voltage specifications.

Memory IC Replacement Considerations

The 24AA01H-I/MS is a direct equivalent regarding function and package. Other variants within the 24AA01 family may serve as substitutes if voltage or packaging differences are acceptable.
