24AA32A-I/MS

Memory IC Overview

The Microchip Technology 24AA32A-I/MS is a 32-Kbit Electrically Erasable PROM organized as a single block of 4K x 8-bit memory. It operates with a supply voltage range of 1.7V to 5.5V and supports a maximum clock frequency of 400 kHz for VCC ≥ 2.5V, or 100 kHz for VCC < 2.5V. The device features an industrial temperature range of -40°C to +85°C and is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.7V with typical standby current of 1 µA
• I2C compatible two-wire serial interface with Schmitt trigger inputs for noise suppression
• Hardware write-protect capability via the WP pin to inhibit write operations
• High reliability specifications including over one million erase/write cycles and data retention exceeding 200 years

Memory IC Applications

• Personal communications devices requiring low power consumption
• Data acquisition systems needing non-volatile storage
• Embedded applications utilizing I2C bus architecture

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 component matches the exact datasheet revision DS20001713P. Cross-reference the manufacturer part number to avoid confusion with similar variants like the 24LC32A which has different voltage requirements.

Memory IC Selection Notes

Select this component when a 32-Kbit EEPROM is required with a wide 1.7V to 5.5V operating voltage range. It is suitable for designs where space is limited due to the compact 8-lead MSOP surface mount package. Ensure the application environment stays within the specified -40°C to +85°C industrial temperature limits.

Memory IC Part Context

This device belongs to the 24XX32A family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24LC32A but differs primarily in its minimum operating voltage, allowing the 24AA32A to function at lower voltages. The family supports multiple package options including PDIP, SOIC, and DFN.

Memory IC Replacement Considerations

The 24LC32A is a related device within the same family; however, it requires a minimum supply voltage of 2.5V compared to the 1.7V minimum of the 24AA32A. Verify voltage compatibility before substitution.
