PIC12LF Overview

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

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
22 distinct suffix patternsExamples: 1552, 1840T39A, 1840T48A, 1501-E/SN, 1501-I/MC (+17 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 PIC12LF Microcontrollers

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For PIC12LF, 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 "PIC12LF" — include the full suffix (e.g. 1552, 1840T39A, 1840T48A). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the PIC12LF product family.

Is PIC12LF a single part I can order, or a family prefix?

PIC12LF is a base / family code from Microchip Technology. You order a full MPN such as PIC12LF1552, PIC12LF1840T39A, PIC12LF1840T48A. The variant table lists 22 orderable lines with different suffixes.

What do the suffix letters on PIC12LF part numbers mean?

Listed suffix fragments include: 1552, 1840T39A, 1840T48A, 1501-E/SN, 1501-I/MC, 1501-I/MS. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Microchip Technology datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of PIC12LF 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 PIC12LF?

Full manufacturer MPN (not just PIC12LF), 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 PIC12LF 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.
