24LC512T-E/MF

Memory IC Overview

The Microchip Technology 24LC512T-E/MF is a 512 Kbit (64K x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V with a maximum clock frequency of 400 kHz and a typical access time of 900 ns. The device supports page writes up to 128 bytes with a maximum cycle time of 5 ms. It is housed in an 8-lead UDFN package and rated for industrial temperatures from -40°C to +125°C.

Memory IC Feature Summary

• Hardware write-protect capability via the WP pin to inhibit array writes
• Schmitt trigger inputs on SDA and SCL lines for enhanced noise suppression
• Output slope control designed to eliminate ground bounce during operation
• Supports cascading up to eight devices on a single bus using A0-A2 address pins

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communication devices needing low-power memory
• Industrial controllers utilizing I²C bus architectures
• Embedded systems requiring hardware-level data protection

Memory IC Procurement Notes

Verify that the ordering suffix 'MF' corresponds to the specific 8-lead UDFN package configuration required for your PCB layout. Confirm the temperature grade 'E' meets the operational limits of your application environment. Ensure compatibility with the 2.5V minimum supply voltage before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 512 Kbit capacity is required alongside strict I²C protocol compliance. The Extended temperature range makes it suitable for harsh environments where standard industrial grades are insufficient. Consider the UDFN footprint constraints against available board space and thermal dissipation requirements for dense designs.

Memory IC Part Context

This part belongs to the 24LC512 family, which shares functional similarities with the 24AA512 and 24FC512 series. While these variants share the same memory organization and interface, they differ in operating voltage ranges and maximum clock frequencies. The 24LC512 specifically targets applications requiring a 2.5V minimum supply compared to the 1.7V support found in other family members.
