The D6840 is a programmable timer module, compatible with the 6840 industry standard. It was designed to be used in a peripheral device for D68xx processors. Moreover, our proprietary IP Core works perfectly as a separate module in applications, where 6840 timer features are useful. The D6840 has three separate 16-bit timers, with individual control and common status registers. The timers may be used for square wave generation with duty cycle regulation. The signal may then be generated as a continuous wave or a single-shot mode. But this is not all - our unique module can be used for frequency or pulse width measurement and comparison. The D6840 has an interrupt, which is useful in a controlling module by the CPU.
As all of our solutions, the D6840 is a technology independent design, that can be implemented in a variety of process technologies.
