Within computer units, there are smaller systems that are designed to perform a single task. These smaller systems are called embedded modules. Embedded modules can perform many important functions within a larger system, but one of the most important kinds of embedded modules are embedded memory systems. As with any component of a system you are designing, it is essential to consider the design and datasheet of any kind of embedded module you select, so you can ensure that you are choosing one that meets the needs of your application most efficiently. Here is a closer look at what you need to know about embedded modules and choosing one for your device.
Embedded Module Basics
Embedded systems can have microprocessors or microcontrollers. With an embedded system built around a microprocessor, there is a memory component built into the embedded system. Complex embedded modules with microcontrollers tend to have separate embedded memory cards. Some embedded modules are plugged into a carrier board, though others work as independent processor cards. The connections used with embedded modules vary, but PCI bus is a common choice for board-to-board connections.
Reasons for Using Embedded Modules
There are several advantages to using embedded modules in designs. Many designers turn to embedded modules when they determine that they can perform tasks required by an application for less expense than building a customized solution. This is especially true for devices that will be manufactured in large quantities. Choosing embedded systems rather than purchasing individual components and investing time in designing and building something to perform the same task can save considerable time and money in the long run. Embedded modules are also reliable and easy to integrate into a number of different devices.
Embedded Modules for Memory
When choosing an embedded module to use for memory, there are several factors to consider. One is the amount of capacity you need, while another is the size of the form factor. You should also consider whether the memory will store sensitive or critical data, and if it will be used in environments with extended temperatures or other extreme operating conditions. Considering these factors will help you select the grade of memory that is best suited to your design.

When you have an idea to build a product to take to market, it&#;s a bit like that moment when racing cars position themselves at the starting line, engines revving, waiting for the flag to drop. You need to be ready for the race, and you need to have all components in place and firing on all cylinders, or you&#;re simply not going to win.We liken this analogy to the process of designing embedded products for several reasons. It points to how critical it is to clear away any obstacles to success. You don&#;t want anything to slow down your process for avoidable reasons, like not having a clear vision of your end goal, or not having the right resources to be successful. We&#;ll cover how critical that is in this article.Additionally, the racing car analogy is a reminder of how competitive the marketplace is. While it&#;s not always true, it&#;s very often the case that the first to market with a really keen technology is the one that&#;s going to win. No one ever said the best technology ever won!So let&#;s talk about the starting point for embedded designs, how to clear away the friction and get obstacles out of the way. Naturally, we have some recommendations for intelligent short-cuts you can make to ensure your success.
Developer teams have a critical decision to make immediately upon launching the planning and design process: Should you use a pre-made module or embark on a chip-down solution?
To answer this question, you need to review a number of important factors:
The following subsections cover each of these topics, with the key considerations.
It is important to seriously evaluate your staff resources, as this is one of the biggest miscalculations we see development teams make. The scope of the project is almost always larger than initially believed during that exciting ideation period when the project is identified as viable.
Why does this happen? We&#;ve found that the rough thumbnail sketch development teams make of the design, build and production cycle very often leaves out some key considerations. These include:
If there is no particular urgency for your team to complete your project, you can skip over reading this section. But you would be a rare breed. And we do want to provide a word of caution that projects without a defined timeline tend to be some of the most expensive, as they often involve developer teams working full time &#; but not at peak efficiency &#; for a lengthy period, instead of focusing their efforts effectively for a shorter period.
For most projects, getting to market sooner rather than later is important. Not only do you stand a better chance of gaining advantage over competitive products, but the sooner you get to market the sooner you realize revenue.
So, given the assumption that timely is better, let&#;s return to the racing car analogy. If you want to get on that track and race for the finish line, you&#;ll want to consider the best ways to build the fastest racing car in the shortest timeframe possible. You can get there much faster if you start with some pre-built, pre-tested components developed by a manufacturer that specializes in designing those components and has the long-term commitment to maintaining them.
As mentioned, it&#;s important to fully validate the assumption that building your own module is a less expensive proposition than starting with a pre-built module.
Another one of the pain points we repeatedly hear &#; in addition to miscalculating the engineering talent needed &#; is underestimating the resources needed to support the full product lifecycle. As developer teams complete their first prototypes and begin the process of testing and iterating on the design, it often becomes clear what a long journey is ahead to ensure its success. Taking a modular approach instead &#; and purchasing your SOM &#; can put you light years ahead on your design, therefore saving an enormous amount of cost in the development cycle.
Additionally, it&#;s important to remember that you are responsible for maintaining the product you deliver to customers. This means you will need to provide firmware updates and support ongoing enhancements, security and bug fixes, which will impact your company&#;s bottom line for years to come.
Not sold yet on starting with a module, instead of building from scratch? Here we will cover some additional key advantages.
With Digi embedded modules, you not only start with a well-tested device, but you have an entire development platform available to you. That includes sophisticated software, code libraries, development tools, programming compatibility tools, documentation and more.
In our white paper, we go into more depth into these topics to help teams perform the extensive evaluation needed to make the best build vs. buy decision &#; from describing some of the key disciplines required of development teams, to a discussion of the critical security considerations to important things to know as you prepare to productize your design and take it through manufacturing to mass production.
