24AA32A/P

Memory IC Overview

The Microchip Technology 24AA32A/P 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™ standards, supporting clock frequencies up to 400 kHz for VCC ≥ 2.5V and 100 kHz for lower voltages. The device operates on a single supply ranging from 1.7V to 5.5V. It includes hardware write protection via the WP pin, a 32-byte page write buffer, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead PDIP package and supports industrial temperature ranges.

Memory IC Feature Summary

• Supports bidirectional data transfer using a standard two-wire serial interface protocol.
• Includes hardware write protection capability controlled by the WP pin state.
• Features a 32-byte page write buffer to optimize sequential data writing operations.
• Incorporates Schmitt trigger inputs on SDA and SCL pins to suppress noise spikes.

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I2C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix '/P' corresponds specifically to the 8-lead PDIP package type. Confirm the voltage range requirements align with the 1.7V to 5.5V specification for the 24AA32A variant. Ensure compatibility with the I2C bus timing parameters, particularly regarding clock frequency limitations at different supply voltages. Check for RoHS compliance status if required by specific manufacturing regulations.

Memory IC Selection Notes

Select this component when a 32-Kbit EEPROM with I2C compatibility is required. The 24AA32A variant is suitable for applications operating down to 1.7V, unlike the 24LC32A which requires a minimum of 2.5V. Consider the 8-lead PDIP package for through-hole mounting needs. Verify that the industrial temperature range meets the environmental conditions of the target application.

Memory IC Part Context

The 24AA32A/P belongs to the 24XX32A family of serial EEPROMs manufactured by Microchip Technology. This family shares common architectural features including the 4K x 8 memory organization and I2C interface. The 'AA' designation indicates the low-voltage operation capability starting at 1.7V. The '/P' suffix identifies the specific physical packaging format used for this part number within the broader product line.
