24LC64 Overview

What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.

Key Features

Footprint / package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), 8-TSSOP (0.173", 4.40mm Width), 8-SOIC (0.154", 3.90mm Width)Land pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
18 distinct suffix patternsExamples: E/P, I/SN, I/ST, F-I/MS, F-I/SN (+13 more). Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Microcontrollers — design-in and field replacement
BOM scrub where only the base prefix is known but suffix is TBD
Second-source checks when the original MPN is constrained

How to Choose the Right 24LC64 Microcontrollers

📦

Match the footprint first

Packages here: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), 8-TSSOP (0.173", 4.40mm Width), 8-SOIC (0.154", 3.90mm Width). Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For 24LC64, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "24LC64" — include the full suffix (e.g. E/P, I/SN, I/ST). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the 24LC64 product family.

Is 24LC64 a single part I can order, or a family prefix?

24LC64 is a base / family code from Microchip Technology. You order a full MPN such as 24LC64-E/P, 24LC64-I/SN, 24LC64-I/ST. The variant table lists 18 orderable lines with different suffixes.

What do the suffix letters on 24LC64 part numbers mean?

Listed suffix fragments include: E/P, I/SN, I/ST, F-I/MS, F-I/SN, F-I/ST. Typically they encode package (8-TSSOP, 8-MSOP (0.118", 3.00mm Width), 8-TSSOP (0.173", 4.40mm Width), 8-SOIC (0.154", 3.90mm Width)), temperature grade, and tape/reel option. Always decode on the Microchip Technology datasheet ordering guide — do not guess from pattern alone.

Which specs actually differ between 24LC64 variants here?

On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.

Can I swap between 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), 8-TSSOP (0.173", 4.40mm Width), 8-SOIC (0.154", 3.90mm Width) packages in the same 24LC64 family?

Only after footprint and thermal review. Packages listed here (8-TSSOP, 8-MSOP (0.118", 3.00mm Width), 8-TSSOP (0.173", 4.40mm Width), 8-SOIC (0.154", 3.90mm Width)) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.

What is the lifecycle status of 24LC64 variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on 24LC64?

Full manufacturer MPN (not just 24LC64), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.

Where is the 24LC64 datasheet?

Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
