24AA01H-I/P

Memory IC Overview

The Microchip Technology 24AA01H-I/P is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-Wire I²C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write-protect capabilities for half the array, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce. It is housed in an 8-lead PDIP package and rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Hardware write-protect functionality allows locking the upper half of the memory array against modification.
• Schmitt trigger inputs provide enhanced noise suppression for reliable data transmission.
• Output slope control minimizes ground bounce effects during signal transitions.
• Low-power CMOS technology ensures minimal active and standby current consumption.

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C). Confirm the 'P' suffix indicates the 8-lead PDIP package type. Ensure the design utilizes a 2-wire I²C bus with appropriate pull-up resistors for the selected clock speed.

Memory IC Selection Notes

Select this component when low-voltage operation down to 1.7V is required. Choose this part over the 24LC01BH if the application demands operation below 2.5V. Verify that the 1 Kbit capacity meets the system's storage needs without requiring larger density devices.

Memory IC Part Context

This device belongs to the 24AA01H/24LC01B family of 1 Kbit serial EEPROMs. It shares functional similarities with other members of the series but differs in minimum operating voltage specifications. The 24AA01H variant specifically supports lower voltage ranges compared to its 24LC01BH counterpart.

Memory IC Replacement Considerations

The 24LC01BH serves as a functional alternative within the same datasheet, though it requires a minimum supply voltage of 2.5V. Other 1 Kbit I²C EEPROMs may be considered if pin compatibility and voltage requirements align.
