24AA02HT-I/MS

Memory IC Overview

The Microchip Technology 24AA02HT-I/MS is a 2 Kbit Electrically Erasable PROM organized as 256 x 8-bit memory. It operates with a single supply voltage ranging from 1.7 V to 5.5 V and supports a maximum clock frequency of 400 kHz via a 2-Wire I2C compatible serial interface. The device features an 8-byte page write buffer, hardware write-protect for the half-array (addresses 80h-FFh), and Schmitt trigger inputs for noise suppression. 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

• Hardware write-protect capability for the upper half of the memory array
• Low-power CMOS technology with minimal active and standby currents
• Integrated Schmitt trigger inputs and output slope control for signal integrity

Memory IC Applications

• Personal communications devices requiring low power consumption
• Data acquisition systems needing non-volatile storage
• Industrial control applications operating in harsh electrical environments

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the MSOP package type and Industrial temperature grade. Confirm RoHS compliance status and ensure the specific revision of the datasheet matches the production lot requirements. Check for any automotive AEC-Q100 qualification needs if applicable to the target system environment.

Memory IC Selection Notes

Select this component when a small form factor surface-mount EEPROM is required with hardware-level write protection. It is suitable for designs operating at voltages as low as 1.7 V. Ensure the application does not require more than 2 Kbit of storage or faster clock speeds than 400 kHz.

Memory IC Part Context

This part belongs to the 24AA02H series of 2-Kbit I2C Serial EEPROMs. It shares functional characteristics with the 24LC02BH but differs in minimum operating voltage. The 'HT' suffix indicates a tape and reel packaging option, while 'I' denotes the industrial temperature range.

Memory IC Replacement Considerations

Direct substitutes include other 24AA02H variants in different packages such as PDIP or SOIC. Cross-family replacements like the 24LC02BH are available but require a minimum supply voltage of 2.5 V.
