24LC32A/SM

Memory IC Overview

The Microchip Technology 24LC32A-I/SM is a 32-Kbit Electrically Erasable PROM 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 supply voltages between 2.5V and 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes low-power CMOS technology.

Memory IC Feature Summary

• Supports page write operations with a 32-byte buffer for efficient data handling
• 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 non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Embedded applications utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOIJ package type and Industrial temperature grade. Confirm voltage requirements align with the 2.5V to 5.5V operational range specified for the 24LC32A variant rather than the lower voltage 24AA32A series.

Memory IC Selection Notes

Select this component when a 32-Kbit EEPROM capacity is required with standard I2C compatibility. Ensure the application environment stays within the -40°C to +85°C temperature limits. Consider the 32-byte page write capability for optimizing write throughput in system designs.

Memory IC Part Context

This part belongs to the 24XX32A family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA32A which supports lower voltage operation down to 1.7V. The 24LC32A specifically targets applications requiring operation from 2.5V upwards.

Memory IC Replacement Considerations

Direct substitutes include the 24LC32AT-I/SM. Verify package compatibility and voltage specifications when considering alternative manufacturers or different suffixes within the same product line.
