24AA025-I/MS

Memory IC Overview

The Microchip Technology 24AA025-I/MS is a 2 Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device features a 16-byte page write buffer, self-timed erase/write cycles, and Schmitt trigger inputs for noise suppression. It supports hardware cascading of up to eight devices and includes ESD protection exceeding 4,000V. The component is housed in an 8-lead MSOP package and is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports high-speed 400 kHz I²C communication with 16-byte page write buffering capability.
• Features low-power CMOS technology ensuring minimal active and standby current consumption.
• Includes Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce.
• Provides robust reliability with over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Applications

• Industrial automation systems requiring non-volatile parameter storage
• Consumer electronics needing compact memory solutions
• Medical electronic devices demanding high reliability

Memory IC Procurement Notes

Verify the specific suffix 'I/MS' corresponds to the Industrial temperature range (-40°C to +85°C) and the 8-lead MSOP package configuration. Confirm that the application does not require hardware write protection, as this variant lacks the WP pin found in the 24AA024 model. Ensure power supply levels remain within the 1.7V to 5.5V operational limits during procurement validation.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is required alongside standard I²C connectivity. It is suitable for designs where hardware write protection is managed via software rather than a dedicated pin. Consider the MSOP package dimensions for PCB layout constraints. Verify compatibility with the system's voltage levels, noting the 100 kHz limit below 2.5V.

Memory IC Part Context

This part belongs to the 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares functional similarities with the 24AA024 but omits the hardware write-protect pin. It differs from the 24LC025 by supporting lower voltage operation down to 1.7V compared to the 2.5V minimum for the LC series.
