So I think when you look at an embedded control system, a microcontroller-based system, it has a large number of components around it. And over the years, the number of components have increased. Now even go back 10, 15, 20 years ago, it will usually have some sort of power management, A to D converters, reference devices, maybe some discrete devices, some study grams, some memory, flash memory, nonvolatile memory. It will have those kind of things.
But over the years, the amount that goes around that microcontroller has increased substantially, and it increased substantially with connectivity. So today, you need a USB, Ethernet, WiFi, Bluetooth, display driver, touch functionality, so just high-voltage sensors and others. So the number of components that go into an embedded control system have really multiplied in the last 20 years.
And we began our journey of really selling things around the microcontroller beginning in about '99, 2000, and then we did a small analog acquisition of TelCom Semiconductor in 2001. And with those resources and adding to it, we started building our analog franchise. And then we didn't really start doing the drumroll of acquisitions until about 2010. But the results have been that we have added all those products now available from Microchip, you can buy them as a kit or you can buy them separately. But if you now look at a reference design for an application and almost find any embedded control application in home, in industry, in car and in any place, open an appliance and look at its printed circuit board, you can essentially have everything on that from Microchip today, a microcontroller, a memory, analog, converters, opt-ins, some sensors, power management, drivers, connectivity, Bluetooth, Ethernet, WiFi, 802.11, anything else.
And so we feel that we have done all that, and now we have a powerful franchise to be able to sell that entire solution. And the challenge in the last couple of years has been now training the sales force to really be able to take that kind of message to the market, and they're doing very well at it. So at this point in time, we do not really feel a burning desire to have to do another acquisition. The valuations are sky-high, will never meet our taste. And number two, we still have high leverage and we're paying down debt. And we have clearly signaled to The Street that when our leverage goes down and then we're still producing a large amount of free cash flow, a more likely use of that free cash flow is the increasing dividend and stock buyback and all that and not the new set of acquisitions. So I think that's where we are because we feel we have completed the solution, we have an enormous scale and do not have the scale disadvantage anymore. And with that, we are going to grow the business organically.
