6. Others
- Data Center Management Software/Tools: For monitoring and managing Broadcom hardware.
- Application-Specific Chips: Such as chips for industrial, automotive, and server management.
II. Part Number Decoding
Although Broadcom’s part number system has minor variations across product lines, it follows a relatively universal pattern. A typical Broadcom part number structure is as follows:
[Prefix][Base Model][Revision][Temperature Range/Environmental Grade][Package Type][Packaging Form][Lead-Free/Lead-Containing][Optional Suffix]
1. Prefix
- BCM: The most common prefix, standing for Broadcom Communication/Connectivity/Mixed-Signal. Used for most networking, wireless, broadband, storage connectivity, and controller chips (e.g., BCM53134, BCM43684).
- BRCM: An older prefix, now mostly unified as BCM.
- Other Specific Prefixes: Some special product lines (especially those from acquired companies, such as former Broadcom Fibre Channel products) may have their own prefixes, but they will eventually be integrated or linked to the BCM main model.
2. Base Part Number
The core part of the part number, usually consisting of 3-6 digits (sometimes with letters), indicating the product’s specific function and series.
The first few digits often represent the product category/series:
- 53xxx: Mid-to-low-end Ethernet switch chips (StrataLite).
- 56xxx: Mid-to-high-end Ethernet switch chips (StrataXGS).
- 88Exxxx: High-end/carrier-grade Ethernet switching/routing chips (e.g., Trident, Tomahawk, Jericho—usually in forms like 88E6xxx, 88E7xxx).
- 57xx: 4-port/2-port server-grade Ethernet controllers (NICs).
- 43xxx: Wi-Fi and Bluetooth combo chips (especially Wi-Fi 6/6E/7).
- 20xxx: Earlier Bluetooth chips.
- 68xxx: Broadband access chips (e.g., PON).
- 7xxxx: Set-top box/home gateway processors.
- 89xxx: SAS/SATA RAID controllers and expanders.
3. Revision
Typically a letter (A, B, C, D...) or a number plus a letter (1A, 1B...), indicating silicon version updates, which may fix bugs or make minor optimizations.
4. Temperature Range/Environmental Grade
- Temperature Range:
- I or Industrial: Industrial temperature range (usually -40°C to +85°C).
- C or Commercial: Commercial temperature range (usually 0°C to +70°C).
- A or Automotive: Automotive-grade temperature range (usually wider, e.g., -40°C to +105/125°C).
- E: Extended temperature range (check datasheet for details).
- Environmental Grade (RoHS):
- G: RoHS-compliant (lead-free).
- GF: RoHS-compliant and halogen-free.
5. Package Type
Represented by letter codes for the physical package form, including:
- PBGA (Plastic Ball Grid Array)
- FBGA (Fine-pitch BGA)
- QFP (Quad Flat Package)
- QFN (Quad Flat No-leads)
- Etc.
The code is usually followed by a number indicating pin count (e.g., PBGA256, QFN88).
6. Packaging Form
- TRAY: Tray packaging.
- REEL/T&R: Tape and reel (suitable for SMT production).
- BOX/BULK: Tube or bulk packaging (less common).
7. Lead-Free/Lead-Containing
Usually indicated with the temperature/environmental grade (e.g., G for lead-free RoHS) or separately as LF (Lead-Free).
8. Optional Suffix
May include customer-specific codes, special certification marks (e.g., AEC-Q100 for automotive grade), speed grades, or internal codes.
III. Examples of Part Number Decoding
-
BCM53134KFSBG:
- BCM: Standard Broadcom prefix.
- 53134: Base model, indicating a 53xxx series Ethernet switch chip (24+2 port GbE).
- K: Revision (Rev K).
- FS: Combined code for temperature/environment/package (check spec sheet for details).
- B: Package type code.
- G: RoHS-compliant (lead-free).
-
BCM43684KFFBG:
- BCM: Standard prefix.
- 43684: Base model, a 43xxx series Wi-Fi 6E (802.11ax) 4x4 combo chip.
- K: Revision (Rev K).
- FF: Combined code for temperature/environment/package.
- B: Package code.
- G: RoHS-compliant.
IV. Notes
Different suffixes may correspond to different temperature grades, packages, packaging, or revisions, directly affecting device availability, price, and design compatibility. For example, BCM53134KFSBG and BCM53134AFSBG may be completely different components.
The above rules are general summaries; the most accurate information should be found in Broadcom’s official datasheets, product briefs, and ordering information. Details may vary slightly across product lines.
Broadcom may change part numbers due to product lifecycle management, with replacement recommendations usually provided on its official website.
