24AA32AX-I/ST

Memory IC Overview

The Microchip Technology 24AA32AX-I/ST is a 32-Kbit Electrically Erasable PROM organized as a single block of 4K x 8-bit memory. It operates on a single supply voltage ranging from 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 I2C compatible two-wire serial interface with Schmitt trigger inputs. It includes hardware write protection, a 32-byte page write buffer, and output slope control. The industrial temperature range is -40°C to +85°C, housed in an 8-lead X-Rotated TSSOP package.

Memory IC Feature Summary

• Supports up to eight devices on the same bus using functional address lines A0, A1, and A2.
• Includes a 32-byte page write buffer to optimize data transfer efficiency.
• Features hardware write protection via the WP pin to inhibit array writes.

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Low-power embedded memory storage

Memory IC Procurement Notes

Verify the specific ordering suffix 'X/ST' corresponds to the X-Rotated TSSOP package configuration. Confirm that the Industrial temperature grade (I) meets the operational requirements of -40°C to +85°C. Ensure the voltage supply aligns with the 1.7V to 5.5V specification for the 24AA32A series.

Memory IC Selection Notes

Select this component for designs requiring low-voltage operation down to 1.7V. The X-Rotated TSSOP package offers a compact footprint suitable for space-constrained surface mount applications. Consider the 400 kHz clock speed capability when designing high-throughput I2C bus architectures.

Memory IC Part Context

This part belongs to the 24XX32A family of 32-Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares core electrical characteristics but varies by package type and operating voltage ranges. The 24AA32A variant specifically supports lower voltage operation compared to the 24LC32A counterpart.

Memory IC Replacement Considerations

The 24AA32AT-I/ST is a confirmed substitute within the same product family, sharing identical electrical specifications and memory organization.
