24AA01H-I/MS

Memory IC Overview

The Microchip Technology 24AA01H-I/MS 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 functionality 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 MSOP package and rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Hardware Write-Protect: Enables protection of the upper half of the memory array via the WP pin.
• Low-Power Operation: Designed with low-power CMOS technology for minimal active and standby current consumption.
• Noise Suppression: Features Schmitt trigger inputs and output slope control to ensure stable operation in noisy environments.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets RoHS compliance standards if applicable to your manufacturing process. Ensure that the voltage supply levels in your design align with the specified operational range to maintain reliable performance.

Memory IC Selection Notes

Select this component when a small capacity EEPROM with I²C interface is needed. The 1.7V minimum operating voltage makes it suitable for low-voltage battery-powered designs. Consider the MSOP package dimensions for space-constrained PCB layouts.

Memory IC Part Context

This part belongs to the 24AA01H family of 1 Kbit serial EEPROMs. It shares functional similarities with other devices in the series but is distinguished by its specific voltage range and package configuration. The 'I' suffix indicates the industrial temperature rating.

Memory IC Replacement Considerations

Compatible substitutes include the 24LC01BH, which offers similar functionality but requires a higher minimum operating voltage of 2.5V. Other variants within the 24XX01 series may serve as alternatives depending on package and voltage requirements.
