24LC32A-I/MS16KVAO

Memory IC Overview

The Microchip Technology 24LC32A-I/MS16KVAO 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 low-power CMOS technology. Key electrical characteristics include a typical standby current of 1 µA and active current of 1 mA. It incorporates hardware write protection via the WP pin and supports page writes of up to 32 bytes.

Memory IC Procurement Notes

Verify that the specific suffix '16KVAO' aligns with official Microchip documentation regarding automotive qualification or specific variant configurations. Confirm package type matches the MSOP-8 specification. Ensure compatibility with system voltage requirements of 2.5V to 5.5V. Check for RoHS compliance status if required by project specifications. Validate temperature range suitability for the intended operational environment.

Memory IC Selection Notes

Select this component when a 32-Kbit EEPROM with I2C interface is required for industrial temperature ranges. Consider the MSOP-8 package for surface-mount applications where space is limited. Evaluate the need for hardware write protection and acknowledge polling capabilities. Compare power consumption metrics against other EEPROM families if battery life is critical. Ensure the host controller supports the necessary I2C timing constraints.

Memory IC Part Context

This part belongs to the 24XX32A family of serial EEPROMs from Microchip Technology. The family includes variants like the 24AA32A which supports lower voltages down to 1.7V. The 24LC32A series is specifically designed for operation starting at 2.5V. These devices share common functional architectures but differ in voltage ranges and specific package options available for different form factors.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24AA32A-I/MS, noting the voltage difference. Other packages in the 24LC32A line such as SOIC or TSSOP may serve as physical alternatives if pinout compatibility allows.
