The ultimate Swissbit product naming guide

A small guide through the designation of our product families
S-45, U-50, X-600, G-26? Anyone familiar with Swissbit knows that these letter-number combinations are the names of our products and product families. But why are the series called this way, what is the meaning of the numbers and what can be read from them? Time for a short introduction!
Let's start with the letters. Of course, these stand for the different product categories of our NAND flash solutions, depending on form factor or interface:
- C: To this day, CompactFlash cards are still a very popular flash-based storage solution and widely used in the embedded and industrial markets (e.g. C-500).
- F: The CFast cards combine the CompactFlash form factor and the SATA interface into a memory card. Swissbit’s CFast cards provide rugged and easy replaceable storage for embedded and industrial systems (e.g. F-800).
- G: Our brand new CFexpress cards. Originally developed for high-end photography and other consumer applications, it combines the super-fast PCIe/NVMe interface with removable memory. Swissbit makes this available to most demanding industrial applications (e.g. G-20).
- S: This includes our SD Memory Cards and microSD Memory Cards. A microSD Memory Card can be easily identified by the “u” at the end of its name, a simplified version of the Greek character μ for the prefix micro (e.g. S-45u).
- N: These are our PCIe SSD modules using the NVMe Based on the M.2 standard every product name includes the m2 in its name (e.g. N-16m2) and series based upon the U.2 standard includes the u2 in its name (e.g. N-30u2). Since the M.2 form factor is available in different lengths, we also suffix the length (e.g. N-26m2 2230).
- X: Our SATA portfolio, covering 2.5", M.2, mSATA and slim SATA modules are suited for all kind of embedded computing applications, and can be easily distinguished by the “m2”, “s” or “m” in the end. Since the M.2 form factor is available in different lengths, we also suffix the length (e.g. X-75m2 2280).
- E: Our Managed NAND BGAs are our solder down form factors and incorporate reliable and easy to implement storage in an electronic system. Available as MMC (e.g. EM-20, EM-30) and M.2 PCIe BGA featuring NVMe 1.3 (e.g. EN-20, EN26).
- U: Easy to spot the U stands for our USB solutions, including USB Drives and embedded USB flash modules in versions 2.0 and 3.1.
- P: Our hardware based security solutions available in USB, SD, and microSD form factors all start with a P for Protection followed by the letter for the respective form factor / series (e.g. PS-450, PU-50n or PS-46u).
Now let's have a look at the numbers. Based on the two or three digits, you can easily get an idea on what flash technology and generation is used in each product.
The first number after the letter indicates the product generation of a series, see the S-50 was introduced after the S-30. But there is much more to find out.
All products with two digits are based on MLC or TLC technology (e.g. S-45, U-50) and in case the last number is a 6 or an 8, than the product is configured in so-called pSLC mode (e.g. S-46, U-48, X-76).
If the series designation contains three digits, then the product utilizes SLC flash memory (e.g. S-455, X-600).
One final note: The series name is only a first indication and logically divides the Swissbit product portfolio into categories. Each series and its associated products are available in a wide variety of feature sets, densities and many different parameters. The detailed specifications of each product is set in the individual Part Number. The Swissbit Product Finder helps you to navigate through our portfolio and identify exactly the part you need.
Now you are clued up on how our series are made up, you might want to have a look on how our part codes are composed. Have a look on the Swissbit Partnumber Decoder.
