24LC32AT/SM

Memory IC Overview

The Microchip Technology 24LC32AT/SM 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 surface-mount package.

Memory IC Feature Summary

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

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communication devices needing low-power memory
• Industrial control applications utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Industrial temperature grade. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation matching the manufacturer's part number specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 32-Kbit EEPROM with I2C compatibility is required for space-constrained designs. Ensure the system voltage remains above 2.5V to maintain 400 kHz clock operation. Consider the 32-byte page write buffer size for optimizing write cycle timing in application software.

Memory IC Part Context

This device belongs to the 24XX32A family of serial EEPROMs from Microchip Technology. The family shares common electrical characteristics and interface protocols but varies by supply voltage range and operating temperature grades. The 'LC' designation indicates the 2.5V minimum supply requirement distinct from the 'AA' variant.

Memory IC Replacement Considerations

Direct substitutes include other 24LC32A variants in different packages such as SOIC or TSSOP, provided the pinout and electrical specifications remain identical. Verify package dimensions and lead pitch compatibility during physical integration.
