24AA044-I/P

Memory IC Overview

The Microchip Technology 24AA044-I/P is a 4-Kbit Serial Electrically Erasable PROM organized as two blocks of 256 x 8-bit memory. It operates within a voltage range of 1.7 V to 5.5 V and supports I2C interface communication with a maximum clock frequency of 1 MHz. The device features an access time of 400 ns and is housed in an 8-pin PDIP package. It is rated for industrial temperatures from -40°C to +85°C, ensuring reliable performance in demanding environments.

Memory IC Feature Summary

• Supports high-speed I2C communication up to 1 MHz
• Operates across a wide supply voltage range from 1.7 V to 5.5 V
• Provides long-term data retention capabilities
• Compatible with standard I2C bus protocols

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics utilizing low-voltage operation
• Embedded systems needing parameter configuration storage
• Automotive applications within specified temperature ranges

Memory IC Procurement Notes

Verify the specific suffix 'I/P' confirms the industrial temperature grade (-40°C to +85°C) and PDIP-8 through-hole package. Ensure compatibility with the target system's I2C voltage levels, as the device supports 1.7V to 5.5V. Confirm that the required memory organization of two 256x8 blocks meets the application's addressing needs before procurement.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is sufficient for storing calibration data or user settings. The 1 MHz clock speed offers faster write cycles compared to standard 400 kHz EEPROMs. Choose the PDIP package for prototyping or through-hole manufacturing processes. Ensure the design accommodates the dual-block memory structure for optimal address mapping.

Memory IC Part Context

This part belongs to the 24AA04 series of 4-Kbit I2C Serial EEPROMs from Microchip Technology. It shares architectural similarities with other devices in the family but is distinguished by its specific voltage range and package type. The series is designed for cost-effective, space-constrained applications requiring reliable non-volatile memory solutions.

Memory IC Replacement Considerations

Direct substitutes include the 24AA044-I/ST (TSSOP-8 package) for surface mount requirements. The 24LC04BH-I/P may serve as an alternative if lower voltage operation below 1.7V is not required, though it typically supports only 400 kHz. Verify pinout compatibility and electrical specifications before substitution.
