CPLDs can deliver. For example,
prepared for portable consumer applications, such as cell phones and PDAs.
For the same market we also supply application notes for using the inherent low power
characteristics and features of the CoolRunner CPLD .
Microcontrollers don’t make the world go round, but they most certainly help us get
around in the world. You can find microcontrollers in automobiles, microwave ovens,
automatic teller machines, VCRs, point-of-sale terminals, robotic devices, wireless
telephones, home security systems, and satellites, to name just a few applications.
In the never-ending quest for faster, better, and cheaper products, advanced designers are
now pairing CPLDs with microcontrollers to take advantage of the strengths of each.
Microcontrollers are naturally good at sequential processes and computationally intensive
tasks, as well as a host of non-time-critical tasks. CPLDs such as Xilinx CoolRunner devices
are ideal for parallel processing, high-speed operations, and applications where lots of
inputs and outputs are required.
Although faster and more powerful microcontrollers do exist, 8-bit microcontrollers own
much of the market because of their low cost and low power characteristics. The typical
operational speed is around 20 MHz, but some microcontroller cores divide clock
frequency internally and use multiple clock cycles per instruction (operations often
include fetch-and-execute instruction cycles). Thus, with a clock division of 2 – with each
