STMicroelectronics M24LR
M24LR variants from STMicroelectronics
M24LR 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.
- 6 distinct suffix patternsExamples: 04E-RMC6T/2, 16E-RDW6T/2, 16E-RMC6T/2, 16E-RMN6T/2, 64E-RDW6T/2 (+1 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 M24LR 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 M24LR, 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 "M24LR" — include the full suffix (e.g. 04E-RMC6T/2, 16E-RDW6T/2, 16E-RMC6T/2). RFQ with reel/tube preference and required date code.
