24LC32AT-I/OT

Memory IC Overview

The Microchip Technology 24LC32AT-I/OT 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 OT package.

Memory IC Feature Summary

• Supports page write operations with a 32-byte buffer for efficient data transfer
• Includes hardware write-protect functionality via the WP pin to secure array data
• Provides Schmitt trigger inputs on SDA and SCL pins for enhanced noise suppression

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Embedded controllers utilizing I2C bus architecture for configuration memory

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and temperature grade. Confirm voltage compatibility, as the LC series requires a minimum supply of 2.5V. Ensure the design accounts for the specific pinout associated with the OT package variant during schematic capture.

Memory IC Selection Notes

Select this component when a 32-Kbit capacity is sufficient for application requirements. The Industrial temperature rating suits standard commercial environments. Consider the 24AA32A variant if operation below 2.5V is necessary, as the LC series does not support voltages lower than 2.5V.

Memory IC Part Context

This part belongs to the 24XX32A family of serial EEPROMs from Microchip Technology. The family shares identical electrical characteristics and functional descriptions, differing primarily in operating voltage ranges and available package options. The 'I' designation indicates the industrial temperature range specification.

Memory IC Replacement Considerations

Direct replacements include other packages within the same family such as 24LC32AT-I/MS or 24LC32AT-I/MC, provided the physical footprint allows for adaptation.
