24LC32AT-I/SNG

Memory IC Overview

The Microchip Technology 24LC32AT-I/SNG is a 32-Kbit Electrically Erasable PROM (EEPROM) organized as a single block of 4K x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 400 kHz for VCC between 2.5V and 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes an 8-lead MSOP package.

Memory IC Feature Summary

• Supports page write operations with a 32-byte buffer to enhance data throughput efficiency.
• Includes hardware write protection via the WP pin to secure array data against unauthorized modifications.
• Features Schmitt trigger inputs on SDA and SCL lines to provide improved noise suppression and signal integrity.

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications operating in standard commercial environments

Memory IC Procurement Notes

Verify that the specific ordering suffix 'SNG' corresponds to the 8-lead MSOP package configuration as documented in the manufacturer's selection table. Confirm that the 'I' designation aligns with the required industrial temperature range specifications for your intended operational environment before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 32-Kbit capacity is required alongside I2C compatibility. Ensure the system voltage remains above 2.5V to maintain the specified 400 kHz maximum clock frequency. Consider the MSOP package dimensions if space-constrained surface mount assembly is necessary for the target application design.

Memory IC Part Context

This part belongs to the 24XX32A family of serial EEPROMs manufactured by Microchip Technology. The family includes variants such as 24AA32A and 24LC32A, distinguished primarily by their minimum operating voltage requirements and specific package options available for different form factor constraints.

Memory IC Replacement Considerations

Compatible substitutes include other 24LC32A variants in different packages, such as 24LC32AT-I/MS or 24LC32A-I/P, provided the physical footprint and pinout compatibility are verified for the existing circuit board layout.
