It covers other important issues about these applications, and is highly recommended. 1 - background There's a sleep current war raging between mcu vendors. Marketing glitz and web pages are the guns; white papers are the ammo, which is being broadsided with increasing frequency. Much of what is claimed is probably true, but more than a little of it is misleading and/or irrelevant. It's truly remarkable just how little current is needed to keep a processor alive today. In the deepest sleep modes even some arm parts claim just 20 nA (nanoamp) of consumption. That's a mere.02 microamp, a number that boggles the mind. In the desktop world cpus suck over 100 amps while active, so i salute the mcu community for achieving such astonishingly-low figures.

Alas, the usual fixes create more problems than they solve. Ul coin Cell Requirements - ul is very strict about using coin cells. Here are the rules, and their implications. Battery Droop over Time - with a load on a coin cell the voltage decays for a while. And then, oddly, stops. Figure on another 10 loss of capacity due to droop. Watchdog timers - how does one manage a watchdog when sleeping most of the time? Summary reviews of tools to profile low-power systems. This isn't really in this report; this is a link to my web site's reviews. Another great resource on these issues is Low Power Design by cmicrotek.


This section is important for firmware designers. Dropping Vdd to cut Current and Increase battery life - you might get some the benefits by reducing Vdd to the mcu, but there are some caveats. Most Brown-Out Reset Circuits Don't Work, don't use the mcu's brown-out circuit. It will not perform as you would expect in most cases. An alternative is presented. Firmware people take note. Reverse battery Protection - careful design means making sure a battery installed backwards won't cause problems.

Leaks and Drains - the business mcu is not the only power consumer on a board. Even the capacitors leak - a lot. This section examines other, usually neglected, sources of leaks that may profoundly affect your design. Decoupling, and Using a capacitor to essays boost Vdd - pick the wrong decoupling capacitor and your system will discharge the battery in a short time. And, given that an ultra-low power system sleeps most of the time and wakes for only milliseconds, can we use a capacitor's time constant to keep Vdd high enough to power the system during the brief time it is awake? Hint: the answer. Running Fast to save power - the vendors recommend running the mcu as fast as possible to get back to sleep quickly, as the total power consumption will be less than running at a slow clock rate. While that is true, it is naïve. There are other factors to watch out for.

Dig into the datasheets and it's not uncommon to find these as "typical" specifications. I investigated what "typical" means. The result: never, ever, use a "typical" specification as design guidance. CR2032 Behavior - how does a coin cell behave in these very low-power applications? No one seems to know, so i took a ton of data. The results are surprising and bode ill for long-lived systems. You may find that less than half the battery's advertised capacity is actually available in a real system.

The idea is that these systems are nearly always in a deep sleep mode, waking bullet from time to time to do something before going back to sleep. Many vendors of microcontrollers (MCUs) claim their products can run like this for decades from a coin cell. These claims are mostly bogus. This report describes the hardware and firmware issues one must consider when designing very low-power coin-cell products. There are a lot of nuances; even decoupling capacitor selection can hugely influence battery life. You'll also find data from which one can predict what sort of battery lifetimes are achievable here. Because the report is very long and covers a number of related subjects, not everyone may need to read the entire thing.

Here's a roadmap so you can get to the sections important for your design efforts: Background - do read this. It gives a bit of information about coin cells, and then shows how the basic assumptions made by mcu vendors are completely off-base. They talk about how long a system can sleep; we care about how much work can be done when it is awake. Three critical points are made in this section: first, coin cells aren't good for more than ten years, second, mcu sleep currents are almost irrelevant, and third, a system running for ten years off a cr2032 battery can only consume.5 ua on average. On Typical Specifications - many mcu vendors make glorious claims about low current consumption and" astonishing numbers.

Unless you use the techniques outlined on this page you'll be lucky to get a year before the battery is discharged. After this was published a number of the vendors called to complain. But none could refute the evidence i provided. December 2014, rev 1: March 2015 - added new info about improved Freescale datasheets. Rev 2: may 2015 - added link to low Power Design article. Rev 3: may 2015 - added update in section 11 about electron pooling. Rev 4: March 2016 - added section 12 about watchdog timers. Today many of us are building ultra-low power embedded systems that must run for years off a battery.

Communication skills are also important since they must interact with hardware engineers, industrial designers, manufacturing operations personnel and end users to develop software products. An entry-level position, such as a computer support specialist or computer technician, can help prospective engineers develop these skills and obtain hands-on experience in the field. Success Tips: gain professional certification. Obtaining certification can demonstrate a certain level of competence and make job applicants more competitive. Product vendors, software firms and professional computing societies, such as the Institute for Certification of Computer Professionals (iccp offer certification programs. Those who seek certification from a product vendor or software firm may be required to work with the company's products, while certification from a professional computing society typically requires a series of examinations, maintenance of membership and periodical recertification. Continue education and training. Since takeaway technology is constantly changing, the job tasks performed by computer software engineers change often as well. Employers, colleges and universities, private training institutions, software vendors and professional computing societies offer continuing education and professional development seminars to help computer software engineers learn the skills necessary to keep up with changing technology.

structures, principles of programming languages, software engineering and computer architecture. Success Tip: Participate in an internship. Employers may prefer to hire those who have relevant experience in addition to a bachelor's degree. Students can participate in internships during their undergraduate education to enhance their employment prospects. Internships also enable students to gain hands-on experience and learn new skills from professionals in the industry. Step 3: gain Related Experience and skills. Since computer software engineers design new software programs, they should have a high degree of creativity. They should also have strong problem-solving, mathematical and analytical skills, as well as the ability to work with abstract concepts.

Long work hours are typical, and travel to meet with other members of design teams might be required. Since much of a computer software engineer's work is done on the computer, telecommuting is an option for this job. Step 1: learn About the career. Computer software engineering includes a variety of tasks and job descriptions, so aspiring software engineers may need to research the field before pursuing education and training that will the prepare them for a particular career path. The types of software that computer software engineers create, test and evaluate include business applications, network control systems, operating systems, databases, middleware and computer games. Software engineers may use a variety of different programming languages. Those who work primarily with computer systems may design and implement data assurance and system security, as well as customize computer systems to meet the needs of clients. They may also set up intranets, which are networks that allow different computers within an organization to communicate. Step 2: Earn a bachelor's Degree.
