24LC512T-I/ST16KVAO

Memory IC Overview

The Microchip Technology 24LC512T-I/ST16KVAO is a 512 Kbit Electrically Erasable PROM organized as one block of 64K x 8-bit memory. It operates on a single supply with a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a two-wire I2C compatible serial interface. The device features a 128-byte page write buffer, self-timed erase/write cycles with a maximum duration of 5 ms, and hardware write protection. It is designed for industrial applications within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using functional address lines A0, A1, and A2.
• Includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Provides hardware write protection by tying the WP pin to VCC to inhibit write operations while maintaining read access.

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the ordering suffix ST16KVAO corresponds to the specific tape-and-reel packaging configuration required for automated assembly. Confirm that the 'I' designation matches the intended industrial temperature range (-40°C to +85°C) for your application environment. Ensure compatibility with the 2.5V to 5.5V operating voltage range specified for the LC series.

Memory IC Selection Notes

Select this component when a 512 Kbit non-volatile storage solution is required with I2C interface compatibility. The 24LC512 variant is appropriate for designs requiring operation down to 2.5V, distinguishing it from the AA and FC variants which support lower voltages or higher speeds. Consider the 128-byte page write capability for efficient data logging applications.

Memory IC Part Context

This part belongs to the 24XX512 family of 512 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes the 24AA512, 24LC512, and 24FC512, which share similar architectural features but differ in operating voltage ranges and maximum clock frequencies. The 24LC512 specifically targets standard voltage applications within the industrial temperature grade.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC512T-I/SN and 24LC512-I/SN.
